Here's a way to get very fast, fluid, and consistent granulated moments on the fly in your live playing: Thanks to Claude Voit for laying out all the pieces for me. Requires: Echoplex Digital Pro with LoopIV, and a MIDI controller capable of sending press/release message strings (e.g. PC1600X, PMC-10) Functionality: When your foot/finger steps/presses on the designated button the EDP will record a very short loop (grain) and loop it until you take your foot/finger off the button, at which time it will reset the loop to silence and be ready to go again. Single pedal press. Usage: Timbral variety for held notes, or extension of staccato notes into granular textures with duration defined by pedal depression. Granular looping is certainly do-able without the complexity of all this press/release programming with a simple SUS Record. However, to achieve what this method does would require you to record a small amount of silence with a second SUS Record to stop the grain. Also, the size of the gran you can capture with a SUS Record would almost certainly be different each time, whereas this method will allow you to get a consistent grain size if you should so desire. Setting up several buttons with different numbers of spacer bytes will allow you to have access to several different grain sizes which you can mix up. Demonstration: Live bass and EDP, done five minutes after programming, with no practice and no overdubs; hence, kinda sloppy, but you can see the potential here. And if you can't, or don't care, then I'm sorry for spamming you with this. I envision this technique being used in a band setting (hence the drum loop accompaniment -- which is not coming from the EDP). Also, I'm using Roland PK-5 MIDI bass pedals as a trigger driving a PC1600X here, so the large pedal swing certainly doesn't make the timing any easier. http://www.neoprimitive.net/jlucas/tmp/granulationexperiment.mp3 (974K) Programming: For the press send this string (where 'n' is the MIDI channel your EDP recieves on [0-F], and '...' is any number of empty bytes [00] which will determine grain size): 9n 26 7F 00 00 00 00 00 ... 8n 26 00 For the release send this string (where 'n' is the MIDI channel your EDP recieves on [0-F]): 9n 3D 7F 00* 8n 3D 00 *This is just an empty spacer byte between the note-on and off of the DirectMIDI Reset command. Don't know if it's necessary or even good to have there. Anyone? If you have changed the Source# of your EDP, then obviously the command strings above will have to be adapted to your change. -Jesse Ray Lucas
