Here's what I need to do. I play live with a Yamaha RS7000 and Ableton live. I want to trigger the "patterns" on the RS7000 using Sysex commands from Ableton. Those commands need to be assigned / triggered in Ableton by several computer keyboard strokes. This is really wierd but here's why.
I am using a Guitar Hero PS2 controller over USB to trigger computer keyboard stokes. I translate the keyboard to midi in Ableton then send it out to the RS7000.. By this I mean Guitar Hero>Ableton Live>RS7000. What I need to do using ABleton is to assign any keyboard command to send a specific sysex command instead of note data to the RS7000.
whew.....I think thats it
