I was wondering if anyone has dug in to the midi cc numbers for root letters and chord types? I would like to use my midi controller as a tool to dial in specific progression that I can play along with but I need to know specific midi cc numbers for each root letter or chord type. Or is this document already available? I already checked the manual and it gives just a range from 0-127.
What exactly do you mean by “Root letter MIDI CC”.
In general, notes are specific midi commands with their own numbering convention. A root letter (as in C,D,E etc) is just another way to describe a specific MIDI note within an octave (yes, a letter will not tell you which octave, but for harmony purposes it’s not that important). But in MIDI terms, it will still be a Note command, if I understand your question correctly.
A range of 0-127 is a range for each and every MIDI CC (let’s set aside the MSB/LSB thing for the moment).
OP is talking about the root note knob. It sets the root of the chord, and has a 2 octave range. This knob responds to CC not midi note.
OP, I haven’t done the math and testing yet, but it’s on my todo list.

Oh, I see. Apparently, I didn’t understand it right.
I’ll see about testing later tonight, but running some math in my head: root note is roughly 128 cc values (0-127) divided by 25 notes (two octaves + 1 note) comes out to just over 5 cc values per note. Chords would be 128/12 so 10.66 cc values per chord.

I will have to experiment. I was hoping I could be lazy and the math would have already been done, haha! Thanks!
