i use a PC laptop i had custom built
with bome's midi translator
and have had for the most part great success
all the issues i encounter are softstep related .....
ableton in conjunction with bomes and my script does work...led feed back as to looper state , visual metronome
minus some issues with the softstep switching scenes even though i have it set to only one scene but i run a max4live plugin as a back up to show me the state of each looper....
if you are on a PC and have bome's professional i can send you my looper set up
my last 100% all improv with a stratocaster, a roland gr-55 guitar synth, launch pad, akai apc-40, softstep, a laptop running albeton live
