DIY Synthesizer with ESP32 (super/hyper saw, aliasing free oscillators, Arduino)

This video shows some impressions of using the ESP32 for a little synthesizer project.
All processing is done on one core with sampling rate of 48kHz.
I've connected a master keyboard via MIDI to a serial input.
The synth actually can play 6 voices together (also with 6 oscillators per voice in unison/detuned mode).
The oscillators are aliasing free (wave forms had been generated in advance to avoid fold back of frequencies above nyquist).
Rough ADSR for velocity and filter is implemented.

You can activate unison support (hyper / super saw) in the following project:
