This is the evolution (mostly cosmetic) from my jamuary 2023-20 arduino sequencer. It now sits inside a unnecessarily small housing that took me lots of tries to make with my rudimentary tools. But I love it. It is USB-C powered, puts out MIDI (and clock) and I managed to program it so you can erase notes (even all with a long press). 3D printed LED seperator and 1/8" screw hole on the bottom. Still only one tempo, chromatic, 1 octave and monophonic.
