@neauoire, have you ever considered an operator for MIDI CC input in orca? As in, an operator that would act like increment, but with a MIDI channel and CC assignment in order to adjust parameters independently of the keyboard and cursor (this would also allow for multiple parameters to be adjusted simultaneously and in a tactile fashion).
I thought I remembered a note input operator mentioned in the readme some time back, but I’m not sure since it’s certainly not in there now. In any case, it seems to me that all of the MIDI output operators could do with input counterparts to aid in the composition process, if at all feasible.
Also, this a big aside and quite a stretch, but it just occurred to me that it could be interesting to record ORCΛ sessions (thinking of livecoding sessions, specifically) for interactive playback. I think this mainly occurred to me because of Asciinema, so I guess I’m imagining something like that but with output (maybe including zooming and such, though maybe it could be overridden otherwise altered) and/or the ability to insert a recorded session into another session (obviously stripped of zooming or bpm info). Anyway, seemed like it could be a neat feature.
