Very nice work!
There's a new feature added on the latest OS update - UI to MIDI. Adjusting knobs on Kemper sends MIDI data when it's enabled. That could be useful for reducing MIDI traffic.
Damian, you might know the answer for this:
Is it possible to get current rig (as sysex data) from Kemper? Is there a magical sysex string for that
That would be so useful when combined with REAPER's ReaScript API. It would be possible to store rigs per-track, per-item or even per-take and later recall them...
