DIY synthesizer soundengine (using ESP32 Arduino) - Little demo of the Roland Alpha Juno like sound

video upload by Marcel Licence

"This video is only a short sound demo of a little sound engine I tried to implement.
I recommend using a stereo output (phones or speaker) for the best listening experience.
It is based on the Roland Alpha Juno synthesis but slightly modified.
The sound is some kind of pulse width modulated saw wave without chorus.
A LFO drives the pulse width for both channels independently creating the stereo effect."
