Question regarding real-time conversion of Audio Signal to MIDI output.

Hi all, for a project I'm attempting to design an instrument that is able to input audio signal (more specifically that of drums) and then convert it to MIDI output all in real-time. Because I'm using drums, I would not take into account the velocity, just the note. I thought about purchasing and using an Arduino MKR Zero. Does anyone have any advice on the subject? Or recommendations?

Thank you in advance :slight_smile:
