Arduino polyphonic synthesizer project (not a Moog) for ESP32 - STM32 - Teensy and more

link to the video

My intention was to make a Moog-like synthesizer. The result is a bit different but contains some features you might know. It is a polyphonic Arduino synthesizer project which runs with 3 oscillators per voice. Tested on the ESP32 it supports 8 voices simultaneously. Each of the 16 MIDI channels can be configured to generate a unique sound. Finally the project is not for the ESP32 only. The flexible design allows the support of different platforms like STM32, Teensy etc. All you hear in this video is directly recorded from the ESP32 Audio Kit without any post processing.

The following images shows the rough architecture of the project: project block diagram

  • CC midi messages ?

    CC midi messages ?

    I have tweaked your code a bit to run on my TTGO T9 and I'm using a Novation Launchkey MINI as keyboard and controller. When I look into your midi mapping " z_conf.ino " I cant find any possible mapping to Control Change (CC) or Program Change (PC) messages. Could you provide an example on how to do that ?

    when debugging MIDI on the ESP I can se that the messages are handled ControlChange(rx): CH: 8 | number: 21, value: 61

    Thanks for an awesome synth ( it is going to be my first euro rack module )

    // David
