Look what I just found…
I guess that may be kinda interesting for the devel-team?
Tried to send these cc127++ from sonic pi too, but it ‘clips’ them to a value of ‘just’ 127.
MAYBE the info kinda help you. I didn’T knew, but I am a n00b.
Have a nice day,
If you read through to the end of that forum thread, a user explains (in technical terms) what is really happening in this scenario (it’s not really a CC message being sent). In short, MIDI CC values are limited to 127 by the MIDI specification.
