Patch of the Week 26: volca modular into mutable clouds

Keyboard Fraud

By John Walden

Chords can be added to the Chord Track with the pencil tool and edited using the Chord Editor.

With the Chord Track, even the most keyboard-phobic and ham-fisted of composers can play in their piano parts!

Like many people, I can write half-decent chord sequences on a guitar, but if I want to perform those parts on a keyboard... well, let's just say my keyboard skills are somewhat limited, and I'm therefore grateful for all the help technology can now offer. There are commercial products that can help you create a convincing performance, of course, but Cubase 7's wonderful, albeit occasionally baffling, Chord Track already includes a keyboard-playing assistant. So, if your keyboard skills are as, ahem, 'good' as mine, let me show you how the Chord Track can help you fake it...

Chord Track Basics

We've already covered a couple of applications of the Cubase Chord Track in previous workshops: using it to re-pitch MIDI and monophonic audio when you want to adjust a chord sequence but don't want to re-record existing parts (June 2013) and in creating harmony parts from audio tracks (July 2013). As a brief reminder, the Chord Track allows you to specify a chord sequence along your project timeline. Once this is done you can select a MIDI or audio track (as long as the audio contains a monophonic performance such as a vocal or instrumental melody part) and, via the track's Chord Track panel in the Inspector window, configure this to follow the Chord Track; Cubase will magically re-pitch notes to fit the chords and scale specified by the Chord Track.

In this example, I used an audio guide track to help me position the chord changes.Much of the time this works well, but for audio tracks in particular it's not fool-proof, and a little manual editing may be required. It's worth noting that the Chord Track's documentation is not the easiest to follow, particularly with regard to the interaction between the Chord Track settings and the Inspector settings for each individual track. Thankfully, for this month's trick the settings are very straightforward.

Write It Yourself

The first step is the creation of the song's chord progression. Thankfully, that still requires a modicum of musical skill (it would be a boring world if we took everything human out of the music-making process — although the Chord Assistant can even help with this if you want it to!). Once the muse has struck, you need to add a Chord Track (Project/Add Track/Chord), and populate it with your chosen chord sequence. As I've usually developed my chord sequences on my guitar, I'll often record this to a click track as an audio guide, but you can just go straight to the Chord Track if you prefer. Creating the Chord Track events is most efficiently done in two passes. First, using the pencil tool, add blank chord events (they appear with a big X in them) for each chord change. Then, using the Chord Editor (click on a chord event to open the Chord Editor), you can enter the appropriate chord.

The key thing (other than picking the right chords!) here is the timing of your chord changes, which is particularly important if you've written and performed the chord sequence on another instrument and the natural groove plays slightly off the beat. Using an audio guide track and zooming in will allow you to position your Chord Track events to hit those chord changes more accurately — you can turn off snap to grid, or select finer quantise values if you need to.

Get Rhythm

With your Chord Track sorted, the fun can commence. First, create a MIDI track and link it to a suitable virtual instrument (I used an acoustic piano patch in Halion Sonic SE in my example project, as shown in the screenshots). Then, in the Chord Track panel of the MIDI track's Inspector, change the Live Transform setting to Chords. This will result in real-time transformation of any MIDI-note data routed to the track's input. Whatever notes you play, Cubase will re-pitch them so that they're transformed into notes that fit the current chord on the Chord Track.

To fake some piano chords, the MIDI track's Live Transform setting needs to be set to 'Chords'.

If you set your locators around your chord progression and loop playback, you can apply almost as much keyboard incompetence as you wish! Cubase will make some sensible chords out of it and, if you record your performance, what you're left with are harmonically correct chords. The one thing to ensure is that whatever notes you play span a reasonable spread of keys: if, for example, you want the end result to be a simple three-note (triad) chord, don't just bash out three adjacent notes as Cubase might transform two of these to the same MIDI note, leaving you with a two-note chord. Instead, span your three fingers a little wider over the keys or, crass as it might sound, use the flat of your palm and play five or six adjacent notes. Amazingly, out will pop the right chords! The good thing about this approach is that it allows you to focus on the rhythmic elements of your performance, which can suffer if you're worrying too hard about fingering the chords correctly.

If you want to create a melodic part, the 'Scale' Live Transform setting can be used.If you change your hand position as you play, you'll find that the transformation process will produce different inversions of the required chords, which adds some useful variety to the performance. You can even play with two hands, perhaps playing a single bass note with your left hand and full chords with your right; again, the transformation process will give you a harmonically correct end result that follows the Chord Track.

Scale New Heights

Perhaps it isn't just the chords that you want help with, though… If you need some melodic parts — even if that's only a few incidental notes — the Chord Track can again be pressed into service. When you add chords to the Chord Track, Cubase will automatically add scale events based on the chords used. If you want more control (or wish to avoid some of the more esoteric scale selections), unchecking the Automatic Scales options in the Chord Track's Inspector allows you to set the scale events manually. You can set the key and choose from a range of different scale types to suit the musical style of your track.

Providing that you've specified the correct scale(s) in the Chord Track, simply switch the MIDI track's Live Transform setting to the 'Scale' option, and any notes that you play will be transformed to fit the scale.

Having It All

For full-on left-hand/right-hand faking, creating two MIDI tracks and a keyboard split within Halion Sonic SE will get the job done.

It's also possible to fake simultaneous left-hand chord and right-hand melody performances, and this can be done a number of ways. If, for example, your master MIDI keyboard includes a 'split' option that allows you to transmit notes above/below the split on different MIDI channel then simply configure two MIDI tracks with two instances of the same VST instrument and set each to receive the appropriate MIDI channel. If you configure the Live Transform settings of one MIDI track to 'Chords' and the other to 'Scale', you can (rather too easily) create some two-handed 'faking'

Alternatively, some VST instruments allow you to limit the range ofIf you switch off the Automatic Scales options in the Chord Track, you can then manually configure the scales used. MIDI notes a patch will respond to. As shown in the screenshot, Halion Sonic SE allows you to do this, and I've set up two instances of a piano sound where each responds to one half of the MIDI note range. Providing you record-enable both MIDI tracks connected to these Halion Sonic SE channels, and configure the Live Transform settings as described in the previous paragraph, you can achieve the same effect.

Guilty Pleasure

While I'm all for improving my own musical skills, I have to admit that since discovering how absurdly easy the Cubase 7 Chord Track makes it to bypass my less-than-stellar keyboard chops, the incentive for me to improve said chops has decreased dramatically — and faking keyboard performances in this fashion has become a bit of a guilty pleasure! Is this wrong? I'll leave you to discuss that with your own musical conscience; I'm too busy laying down piano parts that get the job done to worry about it!

On Your Marks

By John WaldenGet more done in less time, with these workflow tips for Cubase 7.

One of the main frustrations with DAW software is how long everything seems to take — often just long enough for you to lose the creative inspiration you were seeking to nurture! Wouldn't it be nice, then, if your Cubase projects benefitted from a little more flow and a lot less work? Follow this tutorial and hopefully you'll achieve that, because this month I'll offer several tips that should result in a more efficient use of your favourite DAW software.

The Curse Of The GUI

Our interaction with almost all modern computer software is through a graphical user interface (GUI). While the GUI makes it easier to access the multitude of features in today's 'bloatware', it doesn't necessarily make it faster. Certainly, when you use a feature frequently — perhaps dozens of times during a working day — being tied to a mouse and a menu is not the best way forward; you really do need to use key commands. If the keyboard shortcut takes a tenth of the time itWe all spend a lot of time in the project window so it's worth learning the most efficient way to work within it (and that doesn't include those pesky zoom sliders at the bottom-right). takes to execute the same command with a mouse, and this saving is totted up over the 20 or so commands you execute perhaps hundreds of times every working day... well, you do the maths. You'l certainly save a hell of a lot of time and frustration.

Every Cubase user spends a lot of time in the Project window, so for our 'workflow efficiency 101' that's a good place to start. Our main mouse-free, workflow enhancements may seem unglamorous and perhaps a little obvious, but get to grips with them fully and they'll speed up your work more than anything else: let's hear it for Markers, Zooming options and Key Commands...

Marking Time

In all but the simplest of projects, if you know you're going to spend some time working on it, it's well worth creating a Marker track. Cubase provides two kinds of markers — position and cycle — and both have their uses. Position markers simply identify a single point on the timeline. You might use these to identify important locations when, for example, composing to picture, where position markers can identify 'hit' points where the music has to synchronise with the on-screen action. For song-based work, where you have the usual array of defined song sections, cycle markers are often more useful. As the name suggests, these are paired markers that can be used to identify the start and end points of a particular song section.

You can add both types of markers via the Marker track or the dedicated Marker window. Position markers will be added at the project cursor position while cycle markers will be added at the current left/right locator positions. Initial positioning of markers is a one-off task so we can forgive ourselves some mouse work there. However, once positioned, key commands exist to either move the cursor to a marker (position or cycle) and to recall a cycle marker. The beauty of the latter function is that it A project can contain both position and cycle markers but, for clarity, you can choose to filter their display within the Marker window if required.instantly moves the left and right locators to cycle marker positions ready for cycle playback. For moving quickly back and forth to work on different song sections, this is a huge time saver. The 'Recall Cycle Marker' key commands are not defined by default so a visit to the Key Commands window is required to configure these.

The only other issue to consider with cycle markers is whether you position them exactly on the song section boundaries, or whether you set them a bar or two pre and post those boundaries. The latter approach obviously means you get a couple of bars of pre-roll and post-roll around the song section which can be useful when doing multiple takes via cycle-based recording.

Zooming About

Aside from moving between different song sections, the other oft-repeated navigation task is zooming in or out — both vertically and horizontally — on the Project window contents. This can be done in various ways but (unless you're a glutton for self-abuse!) avoid using the horizontal and vertical zone sliders that lurk bottom-right of the Project window; they're too small and fiddly to give you sufficiently precise control (in fairness to Steinberg, similar controls in other DAWs are equally irritating).

Instead, learn just a few of the zoom-related key commands. The most obvious of these are pre-defined by default; horizontal zoom in and out uses the H and G keys respectively, Alt/Option+H or G zooms in and out in a vertical sense, while Shift+F automatically zooms horizontally to show the full length of the project.

However, there are a few other very useful ones that are not pre-defined and you ought to define for yourself. For example, Zoom To Selection Horizontally (rather than just the Zoom To Selection key command) and Zoom To Locators are both very useful. The latter is great when used in combination with the Recall Cycle Marker; two quick key combinations and you have both your song section selected and are zoomed in horizontally to view it. If you then add the To Left Locator key command (by default, 1 on the number pad), then your cursor is all ready to start playback (via the SpacebarBeing able to recall preset cycle markers using key commands means you can get working on the required song section in an instant. key command, of course) of that song section.

In addition, if you need to flip back and forth between two zoom settings, it is worth defining key commands for the Redo Zoom and Undo Zoom options.

Unlock Your Potential

Even just adding these cycle-section selection and zoom key commands to your keyboard repertoire will bring significant workflow improvements, but these commands hold the key to plenty of other possibilities for further time saving. Obvious examples are the key commands for moving between tracks and selecting events on tracks. For example, in the absence of having any events selected within the Project window, the up/down cursor keys will move you through the track list, selecting each track in turn. If you hold the Shift key at the same time, you can select multiple tracks in the same fashion, adding tracks either beneath the current selection or above it.

If you then try the left/right cursor keys, these allow you to select an individual event on the currently selected track (or on the topmost track if you have several tracks selected). Again, adding in the Shift key allows you to select multiple events along an individual track while holding Shift and pressing the up/down cursor keys expands the selection of events onto tracks above/below the current one.

Used in this way, it is very easy to select a horizontal/vertical range in your project manually (perhaps a range that doesn't coincide with one of your song sections already defined by cycle markers). And once you've done that, the default Alt/Option+S key command executes the Zoom To Selection command to perfectly zoom horizontally and vertically into your selection.

Finally, if you use Folder Tracks to organise projects containing lots of tracks, there are various key commands available for folding/unfolding these, although you do have to define them for yourself within the Key Commands window.

Pretty Fly For A GUI Guy

There is nothing dramatic about any of the examples provided above except, of course, the fact that when repeated over and over again in the course of a working day, they will save you a significant chunk of time. However, nothing comes for free and, if you want to benefit from these efficiencies, you have to train yourself to use them — which often means working hard to break your existing habit of reaching for the mouse.

Creating a printout of these Project window navigation shortcuts (most easily done by making some screen grabs of the Navigate, Transport and Zoom sections of theThe Zoom section of the Key Commands window has lots of options for improving your Project window navigation. Key Commands list) will help enormously. For a short while, this might feel like one step back rather than two steps forward but, if you persevere, I promise the rewards will come. It will be one less thing to get between you and the realisation of your musical/production ideas, so it should lead to quicker and more satisfying results. And if not, well, at least you'll have saved enough time destroy a few more brain cells by getting to the pub significantly earlier!  

Faster Transport

While the Cubase Transport panel contains lots of useful information and can be easily customised, there are times when it just gets in the way, especially if you work on a laptop with a modest amount of screen space. All the common Transport panel functions can be executed via key commands — toggling playback on/off, activating record, toggling cycle mode on/off, fast forwarding or reversing and returning to the zero time point, amongst other things — just consult the Transport section of the Key Commands window. You can then toggle off the Transport panel and save some screen space. Oh, and the key command for that is the F2 key!
