if you want to know how a monome works, look up my video, "how does a monome work"
This was designed to work as a performative trigger sequencer for a modular synth.
This device can be found in my Satori repository. There are two versions, one that generates MIDI (Satori Sequencer 64DM), and one that generates trigger signals (Satori Sequencer 64DT). This works with other Satori devices and multiple instances can coexist in a live session.
