I saw this in a link on hackaday and thought there might be someone else
interested:

It's an STM32F427-based audio board with MIDI, audio in/out, and SD
storage. There is a graphical patcher available if you just want to make
music with it.

I've looked through their examples, and it seems to do a fine job as a
wavetable synth. I heard some basic low/band/high-pass filters, but
nothing extreme. It seems that good implementations of filters which
self-oscillate cleanly without falling into chaos/noise are
closely-guarded by the big gear manufacturers.

I use something vaguely similar called a Robertsonics WAV trigger. It
attempts no filtering or synthesis, but does an admirable job of
polyphonic sample playback. In my case, I have it loaded with Mellotron
tape sets.

You won't find me on Facebook.
