Hello everyone. I really want your help for the next idea.

It's an idea using pitch tracking.
In the exhibition hall, when the sound of a musical instrument such as a piano comes into the microphone, it is envisioning a Max Patch that emits a specific MIDI signal according to the input frequency pitch. I would like to ask some of you who have ideas in this area. please!

Pitch detection in max is as simple as it can be.
Check fzero~

But only for monophonic instruments.
Poly pitch detection is impossible in Max.
