4x4 MIDI controller with arcade buttons. It has two working modes: Note - regular mode. You can select scale, root note and transpose by octaves. You can also turn on hold (great for arpegios) Blackbox - mappings for 101music blackbox PAD and SEQ.
It uses two arduino nanos connected by serial software. The 1st nano is used as a keyboard controller and sends the keys to the 2nd one. 2nd receives keys and sends MIDI commands. This is for 16-note polyphony.
