The Hidden Digidesign Pro Tools (part 2)
Pro Tools as a Sequencer
Imagine a recording engineer who just doesnt want to get involved with those fiddly sequencer things that are jammed packed with all the unusable features the consumer market seems to demand, and are a million miles from the elegant simplicity of Pro Tools in its role as an audio recording and editing system. Well, this recording engineer may just find that Pro Tools is all the sequencer he is ever going to need. How many times have you pulled down Pro Tools File menu to create a new audio track, or tracks? Well why not go just a little further down and create a new MIDI track? Go on, it wont hurt. I should say that you will need to have OMS (Open Music System) installed, but you probably already installed it without realising when you first got your Pro Tools software, or upgrade. If you have never done this before I think you will be surprised to find how similar to an audio track a MIDI track appears. It has Record, Solo and Mute buttons, and recording is initiated in exactly the same way as audio. Look at the Mix window - your MIDI tracks are there complete with faders and pan controls. If you look at the inserts view you will see that MIDI tracks too have inputs and outputs, but this time they will be MIDI devices selected via OMS. Easy. And since its so easy, why not hook up that old Yamaha DX7 that has been lurking in a corner of the studio since 1985 and have a go at recording a MIDI sequence into Pro Tools? Its MIDI for engineers, not musos, and it works.
Recording MIDI is culturally a little different to audio. With MIDI, everything revolves round the tempo set in the sequencer - or in Pro Tools - and the metronome click. Pro Tools tempo setting can be found under MIDI Metronome in the Setups menu and, as I mentioned, a suitable sound generator has to be used actually to produce the click. Once some MIDI data has been recorded, the notes can be quantised so that they fall at regular intervals, according to the nudge setting which, when the timeline is calibrated in bars and beats, shows quarter notes, eighth notes etc. This is the sum total of Pro Tools MIDI facilities, and hardened sequencer users will be likely to scoff and say that it just isnt enough. There are no piano roll or other edit screens for instance so how do you correct duff notes? The answer is that you go back and do a punch-in, just as you would with audio. Pro Tools handles audio punch-ins brilliantly, and MIDI punch-in, within the limitations of the MIDI protocol, is just as good. So what would you need an editing screen for? The only significant thing missing from Pro Tools MIDI functions is any ability to match the quantisation of notes to other MIDI data, which is common in proper sequencers and is very useful as you can record a pattern without quantisation, select a good bit that worked, and use that as a quantisation template. Now if Pro Tools could do this, and also match quantise to an audio segment such as a breakbeat, then we really could be getting somewhere. Pro Tools audio quantise function could be similarly improved.
