Arduino-based matrix sequencer running android

Stumbled on youtube on a curious video. The arduin-based iron sequencer is controlled by the application for android, which in turn sends a signal to the Korg Monotron.



Since I myself own the monotron, I was struck by the very idea of ​​people adding an iron sequencer to such a simple synth. It is a pity that the korg themselves did not even stick a simple sequencer into this synth.
