"some kind of MIDI processing utility to convert a note to a CC"
There's max, and I could create a standalone (or max4life patch). I was close to starting a max patch for adding velocity triggering from a pad controller, but I need time making music not programming solutions to overcome design limitations in my gear!
The above request is much easier to implement (and more fun, what about triggering those slices from a chaotic sequencer system in max = +1 ), but it will still cost me precious time I could use getting better at using the octatrack.
I am interested in seeing where this is going, and might give it a go!
