I just noticed on my digitone that the note C2 was in fact the C0 note on OPERATOR on ableton live, is this normal?
Maybe a my question no make a sens ?
There is no globally agreed mapping of octave numbers, because the initial MIDI standard has missed to include a naming scheme.
It varies from manufacturer to manufacturer. Some devices start on C0 (= MIDI note value 0), some on C-1 or even C-2.
The only thing that’s really fixed is that MIDI note value 0 is a C.
I will admit that I feel a little silly to have asked this question, thank you for helping me.
The reason (the complete note name of MIDI note value 0 not defined in the MIDI standard) is what’s silly.
Your question wasn’t.
