I think it would be nice to dedicate one or two midi channels to select patterns and control mutes and solos through MIDI notes.
I know it’s possible now to select patterns using program changes. But it would be a lot more easyer and practical using just MIDI notes, as any master keyboard could do the job.
One possible solution could be as follows:
MIDI channel 13: around five octaves to select patterns from banks A to D (64 notes/patterns in total); another octave to mute or solo the 6 available channels.
MIDI channel 14: around five octaves to select patterns from banks E to H (64 notes/patterns in total); another octave to mute or solo the 6 available channels (same as before).
