I guess we should focus here on audio pitch detection / correction inside the audio editing window?
At least the MIDI part is covered in Audio to MIDI converter. I’m not sure whether this would cover MPE as well. It is not mentioned in the request. However, maybe it is simpler to add MPE there?
For what is worth, there is also Audio Random Access (ARA2) support too.
I hope I am not boring you with these questions. I think it is important to keep the requests modular, connected, and without obvious overlaps.
