Ozone
7
A little while back I set up an ableton project dedicated to control the Octatrack Program change, along with Mutes, Scenes & Fader position.
It used around 12 midi channels & was fiddly to get perfect (using the limited cc editing tools in arrangement view) but worked for my purposes of tweaking a particular song where I didnt have enough hands to do live what I needed.
If you want the file let me know.
Cheers
