RP2040 - tiny2040 - pi pico - piano synthesizer - some kind of polyphonic piano made with Arduino

In this video I will show the piano-like synthesizer made with Arduino running on the tiny2040.
It should be able to run on each RP2040 including the Raspberry Pi Pico.
Instead of an external DAC it uses just a little filter to remove DC from the output.
You can play 8 notes at once and get a stereo sound (especially generated by the chorus and tremolo effect).
Pitch bending is also working and a simple delay effect is implemented also.
