I just set up an awesome preset for JABB with the Edirol PCR-80. It uses every single Slider, Button, and Knob, but it really flows and everything is grouped together intuitively. and you can reach everything you need easily. If anyone wants a copy, let me know. This is the basic arrangement:
SLIDERS - Playing techniques - (Dynamics, Vibrato, Legato, Air Flow/Key Click/Growl, etc.)
KNOBS - Sound Tweaking (Length, Portamento, Var 1&2, Tone Quality, Plunger open/close, Trumpet Releases) (the 4 vibraphone controls are R1-R4).
BUTTONS - Keyswitches for Trumpet, Guitar, etc., etc.
L BUTTONS - Sus. Pedal (for when I don't have my pedal with me) and Pitch bend defeat
If anyone wants a copy, I can post it or email it.
