Yamaha S90

Weighted-action Keyboard Synth

Reviews : Keyboard
Yamaha have taken a weighted keyboard from their latest digital pianos, added high-quality piano samples and Motif sounds, and thrown in a playback sequencer and arpeggiator, and master-keyboard facilities. Left to simmer, the S90 is the result...

Yamaha S90-1.s

Just as one can count on Yamaha to continually revise and develop their core range of synthesizers and keyboard workstations, it's also no surprise to see the company repackaging their existing technology in the guise of a serious master keyboard.

Such was the case with the S80 (reviewed in SOS February 2000), which added a sober black casing, wood-effect end cheeks and an 88-note, weighted piano-action keyboard to a synth engine that was essentially a CS6X with additional piano and keyboard waveforms and voices, plus master-keyboard functions. Jump forward to December 2002, and SOS reviewed the S08, which amounted to a cut-down S80.

And here we are in December 2003, looking at the 64-voice polyphonic S90, which offers similar master-keyboard facilities to the S80, borrows sounds from the Motif range of synths, and adds a brand-new, three-layer stereo piano sample set, plus a variety of acoustic and electric keyboard samples. There is an 88-note instrument in the Motif range — the Motif 8 — and the S90 offers that instrument's Balanced Hammer Effect keyboard (itself based on the action supplied with Yamaha's dedicated digital pianos), but loses the Motif's sequencing and sampling functions. It does, however, retain the Motif's arpeggiator — more of a phrase generator than anything — and grows a number of new Voices and Performances based on the new waveforms.

Physically, the S90 is large, though not much larger than such a substantial keyboard action would warrant, and rather heavy, at 23kg. It's supplied with plenty of buttons and sliders, which enable the synth's operating system to be comprehensively accessed in conjunction with the large (240 x 64-dot) LCD. Rear-panel connectivity is a high point: the main stereo audio out is joined by a pair of assignable outputs and the headphone socket (why do few manufacturers apart from Korg appear to put headphone sockets on the front of their instruments?), four footswitch sockets and breath controller input, an audio input, MIDI In/Out/Thru connections, and a USB port, for linking to a Mac or PC. A blanking panel can also be removed to allow an mLAN high-speed audio and MIDI interface card to be installed. While currently a little expensive, this option is now more of a going concern since more third parties, and Yamaha themselves, are finally supporting the protocol with compatible products.

Optional PLG Boards
Up to three PLG 'modular synthesis' boards can be mounted inside the S90, adding extra sound-making facities, increasing polyphony and upping the multitimbrality of the Seq Play Mix mode, not to mention expanding a Performance to up to seven parts. The current range is as follows:
The PLG150DR: a stereo drum board.
The PLG150AN: an analogue-modelling board.
The PLG150PF: a 64-voice polyphonic piano board.
The PLG100XG: a 16-part multitimbral XG (extended General MIDI) board.
The PLG150PC: a Latin percussion board.
The PLG150DX: a six-operator FM synthesis board.
The PLG150VL: an acoustic-modelling board.
The PLG100VH: a three-part vocal harmony board. This isn't a synth as such, but can be used with a vocalist singing into a mic plugged into the S90's audio input for real-time harmony generation.

Synth & Synthesis

The S90's synth sound engine is based on Yamaha's S&S (sample and synthesis) standard, AWM2. Although basic waveforms are always being modified or improved and effects complements tinkered with, Yamaha's synth voice-generation system has tended to remain similar of late. That means that the basic architecture of the S90 is essentially that of the original Motif family (not the new Motif ES range, which is due any day now). The waveform collection on the S90 is identical (bar some extra acoustic and electric keyboard waves, of which more in a moment), and the factory voices are also similar, although again with new Voices and Performances taking advantage of the uprated data.

The S90 is structured in the usual hierarchical fashion. Synthesis starts with an Element, which contains all the basics for electronic sound production: an oscillator with one of 1347 sampled waveforms at its heart, tuning and pitch-envelope parameters, a resonant filter (available in no fewer than 21 types) with filter envelope, level and pan controls, and an amplitude EG and LFO that can be routed to the pitch envelope, filter envelope and amplitude envelope. Up to four Elements make up an S90 Voice, and those Elements can be given their own key and velocity ranges, making for a mini 'Performance'. However, if you use more than one Element in a Voice, the total polyphony drops accordingly.
Yamaha S90-2.s
S90 editing is via the standard combination of function and soft keys used in conjunction with the LCD, data wheel and Inc/Dec buttons (centre). Sounds are selected using the buttons on the right, while real-time control is afforded over them via the assignable sliders on the left.

In addition to standard Voices, there are Drum Voices, which are broadly similar in synthesis features, though a different waveform/synthesis pairing can be set for every key of the S90's 88-note range. In practice, the synthesis features are a little simpler, but filtering, pitch, tuning, the LFO and so on are all available.

Next, we have the Performance, whereby up to four Voices are layered, with or without velocity switching, and/or split across the keyboard. Performance creation is related somewhat to the S90's master-keyboard functions, which I'll address in a moment. Offsets can also be applied to significant synth parameters for Voices within a Performance (envelopes and filter response, for example), so you don't have to keep creating new Voices every time you'd like a Performance part to be just a little different.

This standard structure becomes a little more complicated if you install one or more of Yamaha's optional PLG synth boards — the S90 can accommodate three — but only in that you'll have to become used to a given board's synth-editing system, and that an S90 Performance can include one Voice from each of up to three boards in addition to the four Voices sourced onboard (there's more on the PLG boards in the box above).

The S90 is generously provisioned with factory settings; 384 Preset Voices and 48 Drum Kits, 128 General MIDI Voices and one GM drum kit, and for the user, 128 Voice and 16 Drum Kit memories (the latter are filled with factory settings when you take delivery of the S90, but can be overwritten at any time). Factory preset Voices are sensibly assigned to different categories on the S90 (for example 'Acoustic Piano', 'Keyboard', 'Synth Lead', 'Drum/Percussion' and so on), and this is a habit you should consider forming as you program your own Voices. The S90 has a sophisticated search facility that lumps similar Voices together, and clearly labelled buttons allow you to access and audition related Voices via the display.
Finally, there are 128 factory Performance memories, but these too can be overwritten by the user. More memories, preset and user, become available if you install PLG boards.

Sounds & Effects

The sound set of the S90 is essentially that of an original Motif, although over 30MB of extra wave ROM is given over to new acoustic and electric piano waveforms. Consequently, the factory sound set is slightly different to allow for the many piano and keyboard sounds.

Yamaha have made a big deal out of the new stereo piano samples supplied with the S90. On first examination, the deal is worth making: the pianos have presence and a lively feel, and play well from the keyboard. The samples are also free from annoying artefacts such as buzzy loops. On closer examination, however, the situation is less clear-cut. There don't appear to be enough multisamples for a start, and so an artificial edge appears where some samples have been keygrouped a bit further than they should. I occasionally found some of the solo preset piano Voices to be a bit plummy, but tweaking edit settings did help here; in any case, not all suffer from this problem.

The three-layer split of the first piano in the set — 'A01 3LayerS700' — is also a little disappointing: there is too much timbral contrast between layers, especially the low- and mid-velocity layers. This contrast makes it very difficult to play a convincing crescendo or decrescendo, as the timbral change at the crossover point spoils the effect. So I wouldn't stick my neck out with the S90 on a solo classical gig. But in a pop (or even ensemble jazz) context, the piano is genuine and convincing, sitting nicely in a mix, and adding quite a sophisticated sheen, particularly to pop arrangements.

I have fewer reservations about the electric piano sounds: Yamaha usually get these right, and the S90 is no exception. Across the board, they're wonderful to play, especially with this excellent keyboard. I liked the Motif's sound set, so it's no surprise that I found the remaining S90 sounds to be well up to Yamaha's high standard. The drums, basses, pads, and synth recreations are all worthy of praise. What's more, if you crank up the volume, you'll notice the S90's really chunky bottom end, which bodes well for dance and electronica work — although that might seem strange considering the sober exterior of this particular instrument.

And how do effects fit into this equation? Again, these are largely the same as those on the original Motif. First of all, there are the Reverb and Chorus send effects, available in all modes. Reverb offers 12 types, including all manner of rooms and halls, plus 'Basement', 'Plate' and 'Canyon' amongst others. Chorus offers 25 effects, with the usual suspects (chorus, flange, and phasing) joined by a number of straight (and not so straight) delay effects. In Performance and sequencer-playback mode (of which more in a moment), a third send effect, Variation, is added; the options here number 25, ranging from more chorus, flanging and phasing effects to distortion, auto-pan, amp simulation, compression, EQs and enhancers.

In addition, there are two insert effects that can be freely assigned in parallel or serially to one or more Elements within a Voice. One insert duplicates the 25 effects offered by the Variation effect, whilst the other offers 104 effects that really do cover all the bases, including off-the-wall treatments such as 'Digital Turntable', 'Attack Lo-Fi', 'Low Resolution', 'Digital Scratch', and 'Talking Modulator'. Lastly, there's a five-band Master EQ section across the S90's main output.

The Arpeggiation Station
It's a bit of a surprise to see the Motif's arpeggiator making the crossing to the S90, though the surprise is entirely pleasant! I like arpeggiators, and this one is about as good as they get. In fact, it's so sophisticated that it moves rather too far from classic arpeggiation to 'instant-gratification' auto-accompaniment. Still, everything has its place.
There are 256 preset arpeggio patterns, and the standard broken-chord patterns are joined by a huge number of what can only be dubbed phrases. These suit different musical styles and instrument types, so you have trills, flute flutters, guitar picking and strums, dance bass grooves and drum patterns.
There is unfortunately no way of creating your own arpeggiation patterns, although those created on the Motif can apparently be imported into the S90 if they've been saved to a Smart Media card first. But the response of the arpeggiation can be tweaked a little. It can be restricted to a given note or velocity range, for example, and the velocity response and gate time can be altered. A global tempo can also be set, and the arpeggiator can, of course, be sync'ed to incoming MIDI Clock. In Performance mode, the arpeggiator can be switched in or out for each part, but it's not possible to have a different pattern for each part. Sadly, notes generated by arpeggiations aren't output over MIDI from the S90, as was the case with the Motif.

Multitimbrality & Sequencing

The S90 lacks a fully featured sequencer, and thus lacks what might be dubbed a 'Song' mode on a workstation synth. It does, as previously noted, offer a playback sequencer, and it's in this mode that you find the instrument's multitimbral setup. And it's here that you also play the S90 multitimbrally from an external sequencer.
Yamaha S90-3.s
Yamaha S90-4.s
Round the back of the S90, as befits a performance keyboard, there are two pairs of sockets for attaching footswitches and pedals, plus a breath-controller input. As well as the headphones socket and dual pair of analogue outputs, there's also an audio input and associated gain control. The right side of the rear panel is where you interface with your computer, either via a Smart Media card, or the USB connection. MIDI interfacing is possible with the usual five-pin trio of MIDI sockets, but also via the blanking panel on the left where the optional mLAN card (which can also carry digital audio) may be fitted. Just visible on the left of the main picture is another panel where the optional PLG boards may be installed (see inset, left).

A button labelled 'Seq Play' takes you into the sequencer-playback mode, which is where you can load and play MIDI files from Smart Media cards located in the S90's rear-panel card slot. Function key 6 in this window is labelled 'Mix' and accesses a pretty fully featured set of mixer pages. On the basic S90 (ie. one not yet expanded with PLG cards), this equates to 16 channels of level and pan controls on one window. You can navigate to the channels via the S90's standard Edit arrows, or via the lower two rows of buttons labelled 1-16 to the right of the front panel (these buttons double as solo/mute functions). Other sub-windows of the Mix page allow you to tweak the sends to the reverb, chorus and variation effects, set up the audio input, and select Voices for each part to play. The S90's Category search facility can also be used here.

Initially, it appears that there are no memories for Seq Play Mix setups, but closer examination reveals a Template window. Here, not only can you select from a handful of factory mix templates aimed at various musical styles, but you can save your own Templates (which consist of Voice assignments, levels, effects settings and so on) for recall at a later time. There are 50 locations, and all can be named and overwritten by the user. Usefully, it's also possible to quickly send all the settings of a Template as a bulk dump to an external sequencer, so that they can be recorded at the beginning of a MIDI file for instant reconfiguration of the S90 whenever that Song is selected.

When using the playback-sequencer function, it's possible to create chains of MIDI Files from an inserted Smart Media card, and transmit individual sequence tracks to external MIDI devices via the S90's MIDI Out. MIDI Files are beamed to a Smart Media card installed in the S90 via a piece of bundled software (File Utility, which works on both Macs and PCs). In addition, your custom Voices and Performances can be saved to Smart Media card without you having to bother with the computer.

If I have one niggle with the S90's multitimbral setup, it's that busy sequences heavy in controller data can cause the sequencer to 'choke' and slow down. Pressing some front-panel buttons during playback — such as you might to search for new Voices in the Mix Template — can also cause small hiccups during a busy performance. More normal sequences, with a bit of restraint on the controller front, work flawlessly.

Free Software
Yamaha S90 05 everything in one
Yamaha are nothing if not generous with the freebies they supply with their instruments these days, and the S90 is no exception. Central to the suite of software bundled with this instrument is the Voice Editor for S90 application (shown right), for both Mac and Windows, which provides detailed and graphical access to all Voice parameters, plus easy computer-based offlining of banks of your custom Voices. The only thing you can really moan about is that you can only load up the Voices from the User bank, and that it's not possible to edit Performances. File Utility is also cross-platform, allowing files to be sent to and extracted from a Smart Media card slotted in the S90. USB drivers for both platforms are also supplied, as are setup files that allow various mix parameters and transports of some popular MIDI sequencers, such as Cubase, Logic and Sonar, to be controlled from the S90.
There is more for PC users, though: they gain SQ01, a full sequencing software package, and the matching Auto Arranger utility that works in tandem with SQ01. Note that there is nothing specifically for Mac OS X yet, though a Mac OS X driver is available at www.yamahasynth.com.
Finally, an additional CD provides demo songs of, and editors for, Yamaha's family of PLG boards.

The S90 As Controller

Quite independently of its synthesis facilities and effects, a lot of people will be looking at an instrument like the S90 just for the quality of its keyboard and the potential offered by its control set and master-keyboard functions.

First of all, I'll just say that I found playing the keyboard a pleasure. It's perhaps a little lighter than the real thing, but allows you to access the maximum expressiveness from the new piano sample set. It's not quite the same as a real piano feel, but it's close, and provides a good halfway-house for someone who spends most of their time working with lightweight, plasticky synth keyboards. Personally, I do find there's an adjustment period, but my fingers don't get as tired on the S90 keyboard as they do on a real piano, and they become used to the action much more quickly.

The keyboard is great for playing all manner of piano Voices, but it can be a slightly disconcerting experience to play more straight-ahead synth Voices and trigger drum sounds from such a substantial keyboard — as it is with any weighted keyboard of this type.

As a source of real-time control, the S90 scores well, starting with velocity and aftertouch sensitivity, pitch-bend and mod wheels (which are located in a slightly odd but still accessible area of the front panel), a pair each of footswitch and footpedal sockets, breath-controller input, and four control sliders. The latter can address up to 20 parameters between them, courtesy of a handy 'Control Function' button.

Beyond this, the S90 functions as a four-zone master keyboard, capable of addressing onboard Voices or sounds from external instruments, depending on what you wish to achieve. Up to four zones can be layered, velocity-crossfaded and/or split across the keyboard, on different MIDI channels when routed outside the synth.

There are 128 memories in which to save master-keyboard setups, though a Master Mode memory could be something as simple as just one Voice assigned to the whole keyboard. Used in this way, you can create your own little sub-set of the onboard Voice library for even easier access than when using the Category search option.

One small point: a lot of synths and keyboards that I play 'auto-sense' the polarity of the footswitch being used for sustain-pedal functions, or have a 'utility' menu item that lets you choose one or the other. Not the S90. The footswitch I had handiest needed a quick solder job to function with the synth! And while I'm at it, the manual also has to be the subject of some criticism. It appears to be trying very hard to be clear and well-organised, but it fails. In a manual of over 130 pages, 32 pages are given over to a Basic Section, and another 60 or so are gathered together as a Quick Guide! The index isn't all it could be, and all I can say in its favour is that the Reference/Function List section centralises all important facts and features, though this still isn't perfect.

Conclusion

Overall, the S90 is a great instrument — fabulous to play, producing a great sound that could stand its own in almost any musical setting from club muso on stage to dance jockey in search of something a bit more ambitious. It'll also impress clients in any studio setting. I would have preferred to be more bowled over by the new piano samples, but you can't have everything. And in any case, they may suit you down to the ground — they certainly work in many contexts, just not a solo classical recital! The effects complement seems a little stingy compared with what's usual these days, but the quality is very good.

Apart from small niggles like the manual, it's hard to be negative about the S90. Overall, the synth offers good value for money, and is expandable (with PLG cards and the mLAN board). The Smart Media slot also makes it a doddle to move data around and access MIDI Files. My feeling is that it would sit well at the centre of a stage or studio rig, and offers a level of playability that's unreachable with a plastic synth keyboard.

Yamaha Motif ES

Music Production Synthesizer

Reviews : Keyboard
Two and a half years after the launch of Yamaha's impressive Motif workstation synth, the range has been further enhanced and upgraded. How much better can it get? We find out...

Yamaha Motif 1.s

Yamaha's Motif family of sampling, sequencing, synth workstations was launched in 2001 (and reviewed in SOS in September of that year — see www.soundonsound.com/sos/sep01/articles/yamahamotif7.asp). Since then, the range has carved quite a niche for itself in a market that has just a handful of major players — the various flavours of Korg's Triton and Roland's recent Fantom S come to mind. Now that Yamaha have decided it's time to upgrade the range, it would seem that they've preferred to take advantage of public familiarity with the Motif name rather than launch a completely new range. Enter the Motif ES (or 'Expanded System').

In response to user requests, many extra features were added to the original Motif over time by way of software updates. But some of the requested facilities required hardware changes that would be impossible to retrofit to an existing instrument. Having made the decision to produce a 'next generation' of Motifs, it was a logical step to develop a new chipset that would make these enhancements easy to implement.

There wasn't a whole lot wrong with the original Motifs, and the technology is still appearing in new gear such as the S90 88-note synth I reviewed last month (albeit with the benefit of the aforementioned Motif software updates built in). But we're nearly three years down the road, and technology has moved on. Hence, ES offers 128-voice polyphony (more than double that of the original), redesigned effects and EQ, even more pattern-generation capability from the arpeggiator, and an operating system that seems generally smoother and faster. More fundamentally, perhaps, there is also a new synth engine. Subjectively, the filters seem to me to have a more 'analogue' feel — more than the average sample-based synth — and the EGs are very responsive. And there's a much larger waveform ROM on board; it's equivalent to 175MB, with 1859 waveforms. Many offer specialised, performance-based samples (for example, guitar string squeaks and harmonics) which are combined in the factory presets to provide voices that produce many of the signature effects of the instruments being simulated (more on this later). Also more numerous are the factory Voices: 768 presets in six banks, and 64 factory drum kits, plus a General MIDI sound set and 256 user Voice memories (and 32 user drum kit locations). That's a lot more Voices than on the original Motif!

Strangely, for an enhanced instrument, a number of features have gone missing, the most odd of which (on UK-bought instruments, anyway) is onboard sample RAM! Yes, in order for your new sampling synth workstation to sample, you'll first have to buy some RAM. To be fair, RAM prices are volatile in the UK at the moment, and it must have been tricky for Yamaha to work out costings that included RAM, but it still feels like an expense is being passed on to the customer so the price of the ES can be kept down. Mind you, I should point out that unlike Yamaha's last few rounds of sample-based products, the ES's onboard sampler benefits from using standard, widely available and affordable DIMM RAM modules — to a total of 512MB.
Other features — such as the option to add Yamaha's PLG synth-expansion boards and the ability to use the ES as a sophisticated master keyboard or real-time control surface — remain from the original Motif, albeit with subtle enhancements here and there.

Essential Motif ES Spec
128-voice polyphonic.
16-part multitimbral.
176MB of ROM sounds (1859 waveforms) with 68 preset voices, 64 drum kits, 128 GM voices, one GM drum kit, 256 user Voices, and 32 user drum kits.
Arpeggiator with 1787 preset and 256 user patterns.
16-track, 226,000-note capacity linear/pattern-based sequencer, with real- or step-time recording, 480ppqn resolution, full cut/paste editing, and recordable controller movements.
16-bit stereo sampler offering 44.1kHz, 22.05kHz, 11.025kHZ, and 5.5125kHz sampling rates (48kHz, and 32kHz are available with the optional AIEB2 board installed). Up to 512MB of sample RAM can be accommodated, with a maximum sampling time of around 50 minutes at 44.1kHz with 512MB of RAM. WAV, AIFF, and Akai samples can be loaded.

Motif-ation

Look quickly, and you'd be forgiven for thinking there were no physical differences between the original and the new Motif. The striking silver livery, the central LCD, and the number and layout of knobs, sliders, buttons, not to mention the front-panel screening and connector complement, is practically identical. But there are differences, some subtle, some significant. One of my favourite changes is the move to big chunky buttons for the sequencer transport controls — very satisfying. There's also more direct, front-panel control over where the real-time knobs and sliders are routed. And I was glad to see a rather Korg-like ribbon controller join the pitch-bend and modulation wheels as a source of real-time control. A few extra buttons allow access to the extra factory preset Voice banks and a couple of other functions.
Yamaha Motif 7.s
There's connectivity galore on the Motif ES, as you'd expect from a high-end workstation: two USB ports, the full set of three five-pin MIDI connections, dual footswitch and pedal inputs, twin stereo analogue outputs (one main pair, and one assignable), a headphones connection, and a stereo analogue input with associated gain control. Above are the Smart Media slot and blanking panel where up to three optional PLG sound-expansion boards may be installed. There's no SCSI, though!

Operationally, existing Motif owners will be on familiar ground — they'll just find more choices in some places and new options in others. Newcomers may have a small struggle, and won't be aided by the manual. It appears to have all the necessary bits, but like many Yamaha manuals I've experienced recently, it is not organised in the most accessible or friendly way. Nor is all information usefully indexed or referenced in what appears to be three tables of contents. If you find yourself regularly looking for a particular fact or operation, get out a yellow highlighter and some post-it notes and customise the manual to suit you — it works for me!

Luckily, the Motif is fairly logical to operate: just pay attention to what you do, particuarly paying attention to the display options that line up with the 'softkeys' laid out under the LCD. The display does get rather busy sometimes, so that it can be tricky to see where you can move a cursor, and in some cases (such as when selecting insert effects), you're not even sure if the cursor is in the right place. Quite often, though, the important information you're looking for (such as how much sampling time is left) can be found by pressing the 'Information' button! It's just under the LCD.

The back panel shows many interesting changes, reflecting perhaps the direction taken by the market for external storage devices. For example, the original Motif's SCSI port has gone; this isn't a surprising change, but not all Yamaha's supplied software is comfortable with the new non-SCSI regime, as we'll discover later (see the 'Interfacing & Software' box at the end of this article). The Motif ES retains the original's built-in Smart Media card slot and USB 'To Host' computer-bound socket, and gains an additional USB 'To Device' connector, which allows ES users to add USB-based storage devices, whether they be hard drives, ultra-compact flash RAM devices or CD-ROM drives (I even successfully tried a USB floppy drive). A CD-ROM drive would be a useful addition: a CD full of native sound libraries is supplied with UK-sold ESs, and it's possible to load samples off CD via the ES's file menu. It is not possible, however, to write data to blank CDs in a CD writer. One way or another, you'll need external storage of some kind, whether it's a Smart Media card or USB device, to store the contents of your 512MB of sample RAM.

Depending on how you work, you may need to buy yet further extra hardware to make your ES work the way you'd expect it to: I instantly noticed that the ES has also lost the original's S/PDIF stereo digital audio output. This can be restored on an ES if you buy the optional AIEB2 board (which also adds digital ins and extra analogue outs).

As with the original Motif, there are three instruments in the ES range, and all three are internally and functionally identical, with the same knob, slider and interfacing collection, as well as the same synth-expansion options. The only way the three ESs differ is in their size and their keyboards: ES6 and ES7 have a plastic velocity- and aftertouch-sensitive synth-action keyboard, of 61 and 76 notes respectively, while the sexy Balanced Hammer Action acoustic-piano simulation is saved for the 88-note Motif ES 8. Actually, there is a fourth instrument in the range, and it's a bit of an orphan: Yamaha are apparently keeping the original Motif 6 on their books as an entry-level workstation option, though obviously this instrument is rather different from the ES instruments it joins.

Sounds
It's practically impossible to summarise or round up the sound of the Motif ES — there are just too many Voices and Performances! But I did develop a couple of favourites. For a chance to hear some of these, head for: www.soundonsound.com/soundbank. I liked the acoustic pianos, and they fit pop and jazz contexts nicely, as most Yamaha pianos do. The acoustic, electric and synth basses are also varied and playable, the latter particularly revealing the ES's solid bottom end.
The ES's guitars are also worthy of note, the acoustics especially offering a bright, upfront sound. The winds and brass are less varied, and the orchestral strings are OK for basses, cellos and some ensembles, but the violas and violins were not so good — they seldom are on an all-round instrument such as this. However, the drum samples are definitely worth a compliment; Yamaha's drum sounds always seem to have the right balance of useable real kit samples, processed examples, bites from drum-machine history and mangled kits aimed at more contemporary music idioms.
Purely synthetic sounds — leads, pads, textures — pour out of this instrument with presence and depth. They're also instructive as to what you, the user, will be able to create under your own steam. The rawest, squelchiest, most '80s-sounding presets work really well and are often teamed up with drums and apreggiations in fun Performances. I'm not usually one to plug one-finger music-making, but some of these are really good.

Synth Engine

In some ways, it's good that Yamaha don't change the way that users access their synthesis technology — the basic concept of the AWM2 'Advanced Wave Memory' sample-and-synthesis system has been stable for a number of product generations. If you stick with Yamaha synths, you'll always know how to drive them, even if the waveforms, converters and synth engine change. And in some ways, this makes it easy for reviewers — after reviewing so many AWM2 products, I can summarise a Yamaha synth's hierarchy in 25 words or less!

For these reasons, existing Yamaha synth owners can skip the next few paragraphs. Those who need reminding of the typical Yamaha architecture can start by considering the Element, which would be a subtractive synth in its own right in other circumstances. An Element's oscillator is a waveform selected from the central ROM (or, on the Motif ES, from any user samples currently in RAM), and this is shaped by the Motif ES's resonant filter (choose from a possible 18 types), an LFO (which includes user-defineable modulation 'waveforms'), pitch parameters, and three EGs — one each for pitch, amplitude and filter.
Yamaha Motif 5.s

There are up to four Elements in a Voice, which is the first level at which the user can play something. A Voice also allows you to mix, key-split and velocity-split the Elements, and add effects — two main effects, and two inserts that can be applied to individual Elements if desired (more detaiIs on the ES's effects engine in just a moment). An arpeggiator can be added to the brew; actually five arpeggiators can be added, and you can then instantly switch between them via five of the keys beneath the LCD.

There are a couple of buzz words floating around in the brochures and advertising for the Motif ES which don't appear in the manual. One of these is 'Mega Voice', a term that was introduced with Yamaha's Tyros home-arranger keyboard. It seemed odd that the company's top pro keyboard should inherit ideas from one of their home instruments, but there is an underlying logic. For a start, there are many automatic music creation tools built into the Motif ES — which you don't have to use, I hasten to add! — and the Mega Voice concept is basically sound. As mentioned earlier, a finished voice, typically a simulation of a 'real' instrument, is given many of the performance attributes of the real thing (for example, guitar voices will offer hammer-ons, string squeaks and body thumps). These attributes are supplied by special samples, and are accessed by changes in playing velocity or by giving them their own key range. In practice, this means that many of these sonic elements are difficult to play in real time with any sensitivity. But some of the ES's new complex arpeggiator patterns take advantage of 'Mega Voice' performance-oriented samples, so that the squeaks, bumps and so on are generated in a musically valid way (see the box on arpeggiation below for more on this).

As always, a Yamaha drum kit can have a sample assigned to each key of your keyboard, with each functioning like an independent synth. Insert effects are also available in a drum kit, along with the two main effects with sends to each from every sample in the kit.

Finally, at the top of the ES's voice architecture is the Performance: four Voices collected together with optional user-defineable key and/or velocity ranges to help create a more involving, complex sound. Arpeggiation can also be added at this level, again with five variations. If you have optional PLG synth boards installed (up to three will fit in the ES), then Voices from these boards can also be added to a Performance, so if you've spent the money, your Performance can be seven Voices strong. Unlike the Combi on Korg workstations (which is made up of up to eight parts), the four Voices in a Yamaha Performance can not be addressed on separate MIDI channels. Nor is there a way, as there was with Yamaha's own SY85 of several years back, to use Performances directly in a multitimbral Song.

Both Voices and Performances benefit from Yamaha's Category Search facility — you'll appreciate it, too, when trying to navigate the hundreds of memories on offer. The Categories are accessed via clearly labelled front-panel buttons (shown on the previous page), and the on-screen display is clear about what you're seaching. Many Categories are actually further divided into sub-categories such as 'Synth Lead' (with hard and soft types), 'Electric Piano' and 'Acoustic Piano'. The Category Search function can be accessed within sequencer Songs and Patterns for selecting Voices. In addition, the Favourites Category allows you to highlight all the sounds you use most, from within all the other Categories, and corral them into one collection. When using Category Search, the Favourites button lets you access all the Voices or Performances you know you like. Finally, your own custom Patches can be assigned to Yamaha's Categories, and this is actually a good habit to get into, even if you then further assign most of them to the Favourites macro-Category!

The Arpeggiator
For me, arpeggiators remain fascinating and fun tools that I am happy to see continuing to be specified on modern music technology. Whether it's a simple straight up-and-down classic device or something much more complex, as here, an arpeggiator is a welcome tool.
The Motif ES's arpeggiator is obviously related to that on the original Motif. It can provide classic broken arpegggio patterns, and breaks the mould by heading into instant phrase-generation territory. In all, there are 256 presets and space for 128 user memories, but there is no arpeggio editor as such with which to fill the used arpeggio memories. What you do instead is convert phrases or bits of data in a Song into an arpeggio, which is using a sledgehammer to crack a nut — but at least you can create pretty much anything in a Song (or import it as MIDI File from your computer software) and turn it into an arpeggio pattern via this method.
The non-standard patterns include MIDI controller patterns and a large selection of stylistically correct instant performance styles for various real-world instrument simulations. Now, this sort of thing isn't my cup of tea (and you can ignore it if it's not yours), but there's no denying the clever programming that's gone on here. Some patterns feel like mini-multitrack sequences, which is effectively what they are. It's in this context that the rationale for those 'Mega Voices' becomes clear. Once they're allied to some of the more sophisticated arpeggiator patterns, you'll hear guitar strumming that includes including rhythmic body thumps and string squeaks, acoustic bass lines that include thumps and slides, and so on. There are also drum pattern arpeggiations that play drum kit voices in Performances, making for one-finger fun.
Arpeggiator patterns can be recorded to a Pattern or Song, or chords can be input that will be arpeggiated on Song/Pattern playback. Real-time fun can be had courtesy of the front-panel control knobs, since one of their options is to change how arpeggios play back. And a nice new touch is that arpeggiations assigned to a Voice, Song or Pattern can be transmitted over MIDI, but not those in a Performance. But note that some of the complex patterns don't work with external sounds, because they won't be programmed in the same way as internal ES Voices.

Effects

Throughout the long history of AWM2 instruments, Yamaha haven't really done much to change the effects configuration of their instruments — until now. The ES sees a big change in the way Yamaha handle effects in a synth workstation. Of course, there are send effects, and here there are two main categories: Chorus (49 types including delay effects as well as modulation) and Reverb (20 types). They are accessed by a send system whether you're working with the individual Elements in a Voice, Voices in a Performance, or Voices assigned to a sequencer Pattern or Song. In addition, there are 116 insert effects. For Voices, there are two freely assignable inserts — and they're quite sophisticated ones, too, many newly designed from scratch for the ES. Splendidly, these choices are maintained when the Voices are used in a Performance, so there's no need for insert effects per se within Performances. However, each part in a Performance also has its own three-band EQ (new for the ES), plus synth offset controls which allow you to customise a Voice from within the Performance without having to overwrite the original Voices.

In Song and Pattern modes, however, the insert effects complement is multiplied by four. You read correctly: eight insert effects, of the same quality and range, can be used within any Song or Pattern. While this arrangement doesn't quite equal the superb flexibility of Korg's Triton, it moves much closer, and is rather more powerful than what Yamaha have previously offered.

There are no new effect names as such — tempo-sync'ed delays and flangers, distortion, rotary-speaker effects and enhancers are joined by the usual 'Jump', 'Slice' and 'Talking Modulation' effects that we've grown to love on Yamaha instruments. Some, however, especially those with a vintage feel, have been redesigned frorm scratch with reference to classic pedals and the like.

Even that isn't even the whole story: a five-band master EQ (similar to that on the original Motif) is here joined by a mastering effects processor, the gem of which is a multi-band compressor, which is perfect for sweetening the mixes output by the ES. Other mastering options include DJ effects such as a dynamic filter, lo-fi and distortion effects — although these don't really count as 'mastering' processes in my dictionary, fun and useful as they are! Finally, of course, there's the aforementioned three-band EQ, which can be added to all four parts of a Performance and all 16 tracks of a sequencer in Song or Pattern mode. It all adds up to a lot of built-in signal processing.

The Motif ES As Control Surface
Yamaha Motif 2.s
As on the original Motif, there's plenty of assignable real-time control potential.
The Motif, when interfaced with a computer, could be used to control the on-screen controls of some music software. The same is true with the ES; in fact, it apparently uses the same control protocol as Yamaha's imminent 01X Firewire/mLAN control surface/audio interface/MIDI interface. But while you'll be able to control lots of on-screen parameters, don't expect it to be completely easy: the Motif has a small number of knobs and sliders compared to the 01X, and you'll have to do a bit of bank switching to access all the channels of a typical session's on-screen mixer. Yamaha do make life a little easier for you, by providing templates that are ready to go with the Motif for Cubase, Logic, Sonar and Digital Performer.
Yamaha are actually quite pleased about the way the ES's control surface integrates with software; not only are the above-mentioned links provided, but in the UK, demos of several Native Instruments software synths are included with the Motif ES package for just this reason.

Sequencing

Sequencing on the Motif ES is, in the same way as on the original, divided into two modes: Pattern and Song. The actual recording and editing process is roughly the same in both, in that up to 16 channels of MIDI data can be recorded in step or real time, with user control over global sequencing parameters such as time signature, tempo, input quantise, and so on. The step-time recording option is particularly flexible, allowing you to use the keyboard and/or the grid display in a way reminiscent of older hardware sequencers. Post-recording editing functions almost equal those in a dedicated software sequencer, except that you have to edit via the Motif ES's relatively small display, of course! Both the Korg Triton and the Roland Fantom S, ES's closest competition, have much larger displays. What's more, the Fantom S offers the option of connecting a mouse and monitor, and the Triton features Korg's nifty touchscreen, which helps OS navigation and parameter editing more than you might think.

Standard editing functions such as quantise, transpose, velocity- and gate-time manipulation, and cut, paste and delete are joined (in Pattern mode) by a couple of nifty functions. 'Remix' basically randomises data on a track, often producing new and interesting material. It's a good trick to apply to tracks on which samples have been recorded and split (more on sample tracks in a moment). There's also the playback-only 'Grid Groove' option, the closest Motif ES gets to groove templates.
Yamaha Motif 4.s
There's no touchscreen, as on the Korg Triton family — you navigate around the display via the usual soft tabs which line up with on-screen options, and by cursoring using the direction buttons to the right of the LCD.

Pattern mode feels, as it did on the original Motif, as if it's borrowed from a home arranger-style keyboard. If you've used pattern-based sequencing on a drum machine or hardware sequencer before, you might find some of the terms confusing; the 64 available 'Patterns' are here merely the memory locations in which you store sequence data. Within each Pattern memory, you can have up to 16 different 'Sections', which more closely resemble what were called patterns in drum machines and sequencers of years gone by. Each Section, which can be up to 256 bars long on the Motif ES, can have a completely different set of Voices assigned to each track, if desired, with full mixing facilities: level and pan, three-band EQ, eight insert effects freely assignable as you need them, two send effects, plus the master effects and master EQ. The integrated sampling sequencer really comes into its own here: not only can Voices be assigned to sequencer tracks, but sampled audio can be recorded there, too, for something not a million miles away from hard disk recording without the hard disk. The upshot is that it's pretty easy to create anything from a scratch backing track to a fully fledged composition.

Each Pattern memory now contains a chain function (only one pattern chain was permitted on the original Motif), which is used to determine the order in which the sequenced Sections you've created will be played back. If your Sections have different Voices assigned to tracks, then the changes show up as program changes. While chaining, it's possible to change mixer settings, so a single Section could be the basis for a whole track with muting and unmuting of parts.

Song mode, meanwhile, provides a more linear, tape-like recording environment. Much of the basic feel is the same as Patterns — you have all the same setup and editing options, and can record samples into tracks. There's a certain degree of interconvertibility, in that Pattern chains can be converted into Songs if you wish. This eradicates the Section boundaries in the Pattern chain, creating a continuous sequence, over which you can then overdub more longform solos, or mix and arrange your Song in a more linear manner. There are 64 Song memories in total. Both Songs and Patterns are lost on power down, so you'll need external storage of some kind to avoid losing your work.

One Song mode trick worth mentioning is the way that individual tracks can be looped by means of an independent switch on each track. If activated, whatever is on that track will automatically loop to the length of the longest track in the Song. So a two-bar drum loop could play for four minutes to provide backing for a piano part, say, without you having to program the drums to last the length of the piano part.

Of course, the ES sequencer can also play external MIDI sounds, or the ES can be played as a multitimbral sound module from an external sequencer. The ES will also load and save data in MIDI File Format, so if you do have a computer, you can rework material with the tools offered by both platforms. The sequencer proved resistant to crashing, except when playing back absurdly controller-heavy data, but as on the S90 I reviewed for SOS last month (see www.soundonsound.com/sos/dec03/articles/yamahas90.htm), pressing patch-selection buttons while the sequencer was running did cause timing problems, which could be annoying.

Freebies
Yamaha are quite good at keeping their customers supplied with extras, most of them free. For example, A Complete Guide to the Yamaha Motif ES is a handy DVD wth a running time of nearly three hours, and it's free to anybody — even people just thinking about buying an ES. It runs through loads of operational routines in a clear manner, and your understanding is really helped by seeing the moves in action, rather than trying to figure out what the manual means.
You may not get a Smart Media card in the box, but once you've bought an ES, make a point of registering it: buy one between now and January 31, 2004, and Yamaha will send you the Atmosfear voice set — 64 synth pads and soundscapes designed in the UK — on a Smart Media card absolutely free. They just need to see a copy of your Motif ES receipt, and your name and address. Note that this offer is only open to Yamaha customers in the UK and Eire, though.
The Motif users' site www.motifator.com also offers a lot of useful content, in the form of tutorials and extra sounds, both free and commercial (Motif voices can be loaded into the ES, remember). I found a detailed document here which explored transferring Voices, samples and sequence data from the older synth to the new, which could be useful if you need to know how.

Sampling

As an owner of Yamaha's A5000 rack sampler, and having co-reviewed the original Motif, I knew what to expect from the sampling side of the ES. But even here there are changes, most notably in the RAM specified by Yamaha: PC100 or PC133 168-pin DIMMs, which are inexpensive, and currently in plentiful supply. The maximum RAM installable is also 512MB in two RAM modules (the original Motif maxed out at 64MB!). RAM can only be installed in pairs, so the minimum loadable will be 128MB in two 64MB DIMMs.

Sampling is undertaken via the stereo analogue inputs, or by internally recording a mix of whatever the Motif ES is playing at a given time. Add an AIEB2 input/output expansion board or the imminent mLAN16E board, and you'll be able to sample digitally, too. Getting samples from your computer isn't straightforward: there's no SCSI connection as there was with on the original Motif, so you'll need a Smart Media card plus a reader attached to your computer to do the swap. A USB device that you can swap between synth and computer will also do the trick, though the manual warns about hot-swapping USB devices, especially those powered by the USB connection.

There's a choice of automatic or manual sampling, with a range of level and input controls (the analogue input, for example, can accept line or mix signals). A wide range of sampling rates is available, from 44.1kHz down to 5.5125kHz (48kHz is available with the AIEB2 option installed). Once you've taken a sample, it can be comprehensively edited, with options including normalisation, trimming, looping, and a good time-stretch. The sampling procedure is elegant, with a dedicated window accessible from Voice, Song or Pattern mode which allows you to record samples directly into a sequence in the way described earlier.

Once there, a MIDI event is also recorded to trigger the sample, and it's possible to split rhythmic material up — especially drum loops and so on — using the Slice function. The Motif ES then creates several more triggers to fire each slice, creating in effect a multisample of the original sample's constituent beats, so that it's possible to slow down and speed up a sequence without compromising the sample in any way — the closest comparison would be with Propellerhead's Recycle software.

Also worthy of mention is Loop Remix function, a Yamaha staple which takes a sliced loop and reorders and/or reverses the slices to create new rhythmic or textural material unobtainable in any other way.
As well as recording samples into the ES's sequencer, you can also use them as the basis for custom instrumental multisampled waveforms. You start with a sample, then this is assigned to a range of notes (and velocities, if desired) that play it on the keyboard, becoming a Keybank in the process. Several Keybanks arranged together as a related multisample become a Waveform, which in turn can be used at the heart of an Element in a Motif ES Voice.

Interfacing & Software
Yamaha 9 Motif ES Voice Editor
Yamaha's free cross-platform Voice Editor for Motif ES. This screen doesn't make it clear, but all Voices, including the six banks of factory presets, are loaded into the editor.
The Motif ES's interfacing is quite comprehensive, but as noted elsewhere in the review, changes have been made that result in some small disappointments. For example, the original Motif's SCSI socket has gone, but in its place is a USB-to-Device socket. However, there was one neat thing about connecting the original Motif to a computer: the link allowed the computer to see SCSI drives and Smart Media cards connected to the Motif, and Yamaha's File Utility software (also supplied with the S90) allowed data to be transferred to and fro. The ES is less straightforward in this respect. The manual explicitly notes that USB devices attached to the ES's 'To Device' USB port will not be seen by a computer attached to the 'To Host' port. More worryingly, File Utility isn't included in the ES's software bundle, so it's not clear if a computer will be able to talk to a Smart Media card inserted into the ES! It seems not.
Certainly, if you have an Smart Media card reader attached to, or built into, your computer, simply moving the card between synth and computer will allow you to move samples and other data easily. But that's yet another expense for the new Motif ES owner. I'd also note that the included version of Yamaha's excellent Tiny Wave Editor sample-editing package still thinks it's living in a SCSI world with the original (SCSI-equipped) Motif and offers no way of directly beaming samples to (or extracting them from) the Motif ES — you need to move Smart Media cards or other USB storage devices to and fro. There is no other way.
Computer interfacing will become more interesting, though, when Yamaha's new improved mLAN board — the mLAN16E — becomes available later this year: audio and MIDI can be passed in both directions down a single cable, so it seems that the sampling inputs and insert effects become useable within whatever sequencing environment you use.
Other supplied software — the excellent Voice Editor application and the PC-only SQ01 sequencer — function perfectly via the USB connection, as do other MIDI applications. None of the supplied software is for Mac OS X, the now default OS for Apple computers. Nor will the supplied software run in Classic emulation mode. A Mac OS X driver can be downloaded from www.yamahasynth.com, but there was no news of anything else as we went to press.

Motif ES As Master Keyboard

Not only can the Motif ES be a sequencing, sampling synth workstation, it also has something to offer as the master keyboard in a larger MIDI studio. These facilities have been inherited from the original Motif, via the recent S90 synth. Essentially, it's possible to layer, key-split or velocity-split up to four ES Voices, up to four patches on external MIDI instruments, or a mix of the two — like a super-Performance that's not limited to sounds on the ES itself.

Master keyboard setups are saved into one of 128 master memories. Unusually — and usefully — these memories can accommodate practically anything located on the ES. It's possible to save anything to a Master memory, whether that be a Voice, Performance, Pattern or Song. This facility is offered to make what is a deep and complex instrument easier to navigate when you're in a hurry. Simply plonk all your favourite Voices, Performances, Songs or Patterns in Master memories, and they can be recalled more quickly than by scrolling through the rest of the OS in normal circumstances. The feature is especially useful for live users of the Motif ES: you can set up a chain of whatever you want to use on stage for instant recall. A footswitch can also step through the Master memory list, if desired. So you could have a Song in memory 1, followed by a Voice to vamp with during a break between songs, then the next song and so on. For studio users, the master memory list could be treated like a 'favourites' list, so that your most commonly used data is more accessible than by other means.

Conclusions

In summing up the Motif ES, I can only echo comments made in the review of the original Motif. It features everything you'd expect — bar sample RAM! — and should be able to do anything reasonable that you want it to. The interface is neutral enough to suit any style of music you'd want to create with it, and the huge waveform ROM, coupled with the large number of presets, covers enough bases that you won't have to buy PLG cards unless you really want to! The synthesis capabilities are familiar, yet somehow better than previously, particularly as regards effects implementation, and the sound is solid and vibrant. It's also good to see the sampler and sequencer so well integrated.

Overall, the often subtle but significant changes to the Motif range indicate more of an evolutionary move up the ladder, rather than something radically different from what has gone before. Aspects are better, certainly, but not in the consistent way that made the original Motif such an eye-opener. That said, Motif ES is, and will remain for some time, one of the 'must-test' options for those seeking an all-in-one synth/sampling workstation. The choice won't be easy, but make it an ES and you won't be disappointed.

Clavia Nord Lead 2X

Virtual Analogue Performance Synth

Reviews : Keyboard
The follow-up to Clavia's Nord Lead 3 is not the Nord Lead 4 (well, not yet, anyway), but a beefed-up version of the Nord Lead 2! We find out why, and how it improves on the original.

Nord 1.s

With their Nord Lead 3 (reviewed back in SOS July 2001 — see www.soundonsound.com/sos/jul01/articles/nordlead3.asp), Swedish virtual-analogue pioneers Clavia produced an instrument with a remarkable user interface. The continuous knobs ringed with LEDs were an absolute delight, and the inclusion of an aftertouch-enabled keyboard and a real display for patch names seemed a significant (and overdue) advance over the earlier Nord Leads. With these things in mind, you'd hardly expect the next Clavia synthesizer to be a reworked version of the six-year-old Nord Lead 2. Of course you've spotted the title of this review already, so you know that's exactly what Clavia have done. If your first question (as mine was) is 'Why?', check out the box of the same name over the page. If that takes care of 'Why?', then read on for more on exactly what the Nord Lead 2X — and its rack counterpart the Nord Rack 2X — have to offer.

Red Again

The Nord Lead established itself in the mid-'90s as the classic design for virtual-analogue synths. I reviewed the Nord Lead 2 back in September 1997 (see www.soundonsound.com/sos/1997_articles/sep97/clavianordlead2.html), so it was something of a surprise to meet it afresh in 2003. Especially because, with the exception of a detachable power cord and an 'X' in its name, I couldn't immediately spot the enhancements. Rather than rehash its spec or re-twiddle its knobs, why not check out the 'At A Glance' box below and the pics above and over the page for a refresher of what's what. For convenience here, I'll sum up the Nord Lead 2 as a twin-oscillator analogue-modelling synth with four-part multitimbrality, each part being referred to as a 'Slot'. This structure allows for layering of patches, split keyboards or control via four separate MIDI channels. As there are no onboard effects to play with (unless you count the MIDI delay and distortion in the filter section), the 2X's four audio outputs are welcome, and may be used to process each slot individually if you wish. Perhaps my favourite Nord feature is its 'morphing', which is cleverly implemented to extract the maximum sonic diversity from the minimum knob count (more on this in that box below).

For traditional analogue tones, the oscillators sound fine, the filter recreations are pleasing, the envelopes are snappy and the modulation options are well-chosen. And with no menu-hopping required to program patches, you know pretty much where you are at all times with this intuitive red metal synth.

Time gives a chap the opportunity to reflect, and it was interesting to revisit the sounds and operation of an instrument that I quite enjoyed, but never truly embraced, and view it in the context of the competition six years on. Perhaps surprisingly, the new model holds its own rather well, although the competition has thinned out somewhat lately. In the UK, it slots into the 'around £1000' price bracket, nestling below the various Virus keyboard versions but well above the (recently discounted) Novation K-Series and the much cheaper (but only eight-note polyphonic) Alesis Ion.

The Nord Lead 2X At A Glance
Four-octave velocity-sensitive keyboard with no aftertouch.
Octave Shift buttons (±2 octaves).
Keyboard-split function.
Wooden pitch stick that changes the pitch continuously, offering pitch-bend or natural vibrato in one controller.
Modulation wheel offering control over several destinations or over the morphing feature.
One pedal input for sustain and one for the expression pedal.
Four unbalanced audio outputs — each slot may have its own output or a variety of mono and stereo configurations.
Three-digit LED display, 26 knobs and 27 buttons for program editing.
The two oscillators generate sine, triangle, sawtooth or pulse waves with adjustable width. Additionally, Oscillator 2 has variable coloured noise with a unique sync option producing decidedly digital-sounding waveforms; it also features hard sync and may frequency-modulate Oscillator 1. The ring modulator produces atonal effects as the two oscillators are cross-processed, and when ring modulation is active, the FM Amount knob controls the modulated signal's timbre and pitch. A little trick to regain control of FM amount when the ring modulation is active involves using the mod wheel and setting its destination to FM.
Clavia's distinctive filters include 12dB-per-octave low-pass and 24dB-per-octave low-pass, band-pass and high-pass types, as well as a combination notch and low-pass filter. Envelope amount is controllable via velocity and keyboard tracking may set to full, two-thirds, one-third or off. A Filter Distortion button adds a preset amount of distortion.
Modulation is catered for by two LFOs with a variety of waveforms and destinations, although you can select only one destination per LFO. LFO2 also controls the rate for the simple (but effective) arpeggiator. A MIDI Echo function is present, and can be set between one and eight repeats (as this generates new MIDI notes, it can eat into polyphony if used gratuitously). A modulation envelope (attack, decay) for Osc 2 pitch, FM amount and pulse width is included too.
Each knob may be programmed for velocity control or may be 'morphed' by the modulation wheel (or pedal) to continuously fade between two sets of values. Some of the Nord's most complex sounds are created this way, the knobs controlling multiple value changes simultaneously.
Up to four program Slots (A-D) may be active at once for layered or split keyboard effects. There are dedicated buttons to select the Play mode from the following options: poly, legato, mono, unison mono, and unison poly. Finally, there's a Portamento control.
All the Nord 2X's control knobs and switches for program editing transmit and receive MIDI Control Change messages. Other MIDI goodies include synchronisation of the LFOs, and remote triggering of the filter and amplifier envelopes or velocity control from separate MIDI channels for some fascinating sequencing possibilities.

So, What's New?

Basically, the Nord 2X offers more patch storage, increased polyphony and better D-A converters. The Nord Lead 2 had a respectable 16 notes of polyphony — four times the amount of the original Nord Lead. The new model sees a further increase, cranking the total up to 20 notes. An extra four notes may not seem too radical, but they really count when using layered patches.
Nord 2.s

The biggest change of all is in the amount of memory available. A limitation of the original Nord Lead 2 was its meagre internal storage — just 40 user Programs and, worse, user Performances (multitimbral or layered collections of up to four patches) could not be stored internally at all — you needed to purchase an additional battery-backed SRAM card. Happily, things are far better in the 2X model (which has no card slot), as internal memory now consists of 990 single sounds — 396 of these user-programmable, 594 ROM factory sounds. Furthermore, there are 400 Performances; annoyingly, 300 of these are still fixed in ROM, but there are 100 RAM Performances in which to store original creations. Finally, where the Nord Lead 2 had 10 analogue drumkits, the 2X has 40, and all of them are user-programmable. Each percussion kit features eight drums, configured in eight zones across the keyboard. See the 'Sounds' box over the page for more on these.

Having so many sounds on board is both a blessing and a curse. If it sounds as though I'm never satisfied, let me explain; the curse part boils down to issues surrounding navigation. The Nord Lead series (prior to the Nord Lead 3) relied on a three-character display and pretty much got away with it. Now, though, with almost 1000 single sounds to call upon, locating a particular patch amongst the throng is a challenge — and that's even before you tackle the problem of remembering the patch number you want. For a start, you cannot leap directly to a particular bank. Instead, you must scroll through the onboard patches until you reach your destination. Holding down the shift key increments patches in steps of 10 but, even so, getting around is fairly laborious.
Nord 3.s
The rear panel is almost identical to that of the original Nord Lead 2, with individual audio outs for each of the synth's four 'slots', sustain and expression pedal inputs, and a headphone socket. Shame there's still no MIDI Thru, though.

Programs are divided into Banks, each containing 100 patches. Banks are represented numerically on the display by their first digit and a dot. The two remaining characters represent the patch number from 0-99. Thus Bank 1, program 21 is shown as '1.21' (bank number zero is represented as a blank, for greater clarity). Percussion kits are located at the end of each bank and are preceded by a 'P' so '3.P0' is not an affectionate nickname for the cheerful Star Wars robot, but the first kit in Bank 3.

Performances are organised into four banks of 100. They are named according to the convention 'A0' to 'L9' (the letters 'I' and 'K' are excluded, as these characters don't work terribly well in the display), so '4.B1' refers to Bank 4, Performance 12. When you create a Performance, it automatically takes copies of each Program it uses. This means you can tweak each in turn with no fear of overwriting the Program upon which it is based, although you can store your work in a standard Program bank if you wish. Holding down multiple slot buttons at any time is a quick and easy way to try out new layers. All this adds up to a simple, flexible system.

If this all seems familiar, you're forgiven, as this synth is architecturally identical to the original Nord Lead 2; indeed, all patches are 100-percent compatible with it. The most significant enhancement left to mention is one you may not instantly notice: improved digital-to-analogue converters. The Nord Lead 2X contains high-resolution, low-noise 24-bit DACs running at 96kHz (the Nord Lead 2 had 18-bit converters). The end result is a clean-sounding synth with a nice sizzle and bite, although the original was no wallowing hippo itself. For more on the sounds in the 2X, see the 'Sounds' box below.

Sounds
With so many patches on board, auditioning them all took me several days; I hope you'll accept my description of a small cross-section of favourites. Note that the names are retrieved from the manual due to the display limitations mentioned elsewhere in this article. For a chance to hear these sounds, surf to www.soundonsound.com/soundbank.
PERFORMANCES
C4: 'Split Flute Echo' — this Performance splits the keyboard, placing an analogue bass in the left hand. It uses the built-in MIDI delay effect to liven up a sweet right-hand solo.
D0: 'Cave Pad' — this isn't so much a pad as a tuned resonant percussive patch based on the noise waveform of Oscillator 2. Place this in a cathedral-type reverb for an awesome, atmospheric sound.
G4: 'ARP Erasure' — two layered parts feature here, with their arpeggiators set to randomly emit a lively, bright series of patterns. I warrant they'd bring a smile to the impassive face of Vince Clarke himself.
G7 (and also 2.G7): 'Synth Brass Section' — analogue brass sounds that sound classy even when compared to those in my Oberheim Xpander. I can't think of higher praise than that.
H6: 'Hybrid WurliRhodes'— One of several highly useable electric pianos.
L2: 'Plastic Bass' — there are many chunky, powerful basses. This is a rather Jarre-ish example.
2.L1: 'Short Wave Opera' — vocal textures with added noise making for an evocative pad.
There is also a range of specifically programmed organ performances, such as the excellent 'All Even Harmonics' located at 1.H1. Clavia hint at a rotary speaker using simple vibrato and morphing capabilities. Throughout the organ performances, slot D contains a 'click' and, of course, individual slots can be turned on or off for variations. It's not quite the simplicity afforded by drawbars, but it's not bad either.
PROGRAMS
There are literally hundreds of these, encompassing the whole range for which analogue is justly famous — and there are even a few successes where, traditionally, analogue struggled to convince. Naturally, the synth is packed with basses, solos, pads, brass, strings, electric pianos, bells, sound effects, arpeggios and more. Mostly, they are of high quality, and it seems unfair to single out any for special praise. Nevertheless, I must mention at least a couple of favourites, such as 2.99, entitled 'Rain'. Add reverb to produce a realistic downpour, or raise the mod wheel to transform the sound into something reminiscent of frying bacon. For more conventional uses, check out 4.73, 'ScoopPad', which uses velocity morphing and the mod envelope sweeping the pitch of Oscillator 2 to produce a warm pad with a marvellous initial glitch. I could (and did) noodle on that one for ages. Naturally, Clavia have the whole gamut of squidgy analogue sounds covered (eg. 2.77, 'HighPass 303') and even 'realistic' sounds, such as acoustic guitar (5.22, 'The Thumb') and solo strings (8.26, 'Solo Cello') are bundled in too.
PERCUSSION KITS
The percussion kits offer no less than eight simultaneously playable virtual-analogue sounds in a single slot, with only one limitation (each voice in a kit has to share LFO settings with its fellow drums). Each sound is mapped over a fixed area of the keyboard known as a zone. The eight zones are divided between notes 'C'-'E' and 'F'-'B' in each of the Nord Lead 2X's four octaves. An ingenious method of selecting the voice to edit involves simply hitting any black note within that zone. Having fixed zones means you can't work with General MIDI drum maps, but I suspect few potential Nord customers will be unduly worried by this! The analogue percussion voices supplied include zappy bass drums, noise-blast snares and toms, and metallic percussion, but you can tailor them all to taste using the Nord's synthesis options. They sound pleasantly Kraftwerk-like to me, especially when layered and arpeggiated in a Performance.

Conclusion

The Nord Lead 2X is a means of continuing production of the Nord Lead 2, whilst along the way exploiting updated components. However, many of the reservations I expressed in my original review remain. The keyboard has no aftertouch, there is no MIDI Thru port and there are no onboard effects. Mind you, neither these niggles nor a relatively high price have prevented the Nords from gaining a strong following, and the extra improvements are worthwhile. Four more notes of polyphony proved very handy when using the 2X multitimbrally, and the massive increase in onboard storage is also welcome. Perversely, having so many patches now makes the display more of a liability — identifying and locating favourite patches requires some method of your own, such as the famous 'writing on bits of paper' technique or the use of patch lists in a computer-based sequencer (if you use one). Those 24-bit DACs sound good too.

In terms of sound and performance, you know what you're getting with the 2X — namely a synth that delivers plenty from a (largely) intuitive interface and which has a character all of its own (indeed, some people are happy to admit that they prefer it over the Nord Lead 3). Ultimately, it makes perfect sense to improve any instrument for which demand remains high, and the fact that Clavia have breathed new life into this range suggests that they see no reason to abandon their classic line just yet.
