Need a simple unlocked patch to allow a 3 button usb controller (Logidy UMI3) to do the following:
button 1: Pressing will activate the Multipurpose Transport Button on a Looper device in the current armed track in Ableton Live
button 2: Pressing will arm the the adjacent track to the right in the arrange window, or return to the first track if pressed while on the last track (the last instrument or audio track - not returns or master tracks)
button 3: Pressing will arm the adjacent track to the left in the arrange window, or go to the last track (the last instrument or audio track - not returns or master tracks) if on the first track
The Logidy can be set to send midi notes, CC, program changes, etc. Manual available online. ... Manual available online. For this job, you can assume it provides midi notes 125, 126, 127 for the three buttons.
This should be 1 hour of work for a solid max/msp coder with knowledge of the max for live live.property, live.object, live.path and live.remote patches.
