Behold this awesomeness! PatchworkBoy has written a set of Arduino sketches to add a bidirectional physical interface to the free and open-source VCV Rack software Eurorack synthesizer.

It uses both an 8×8 NeoTrellis with Feather M4 and a NeoTrellis M4 to interact with a 64 step trigger sequencer module from Trowasoft and some MIDI mapping modules from Stoermelder.

Check out the code and Rack file here. I look forward to trying this out and doing a demo on a livestream soon!
