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


video by Marcel Licence

"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.

I am preparing a little arduino project for sharing. It will be available soon..."
