Quick addition to yesterday: sustain! This also opened up the option for stride in the left hand, in this case between SNES bass and strings. Also allowing for more tasty extended chords. :)

Ok last addition for today: got the lil display to show notes per channel, and squeezed in letters for which chip is being used for said note/channel (s for SNES, y for ym2612, g for game boy). Hard to see on camera but it's there. :)

128x64 btw so super tiny. Hard to fit much. 😅
