It's a piano It uses that dumb control scheme where the key a=a, b=b, etc. low e=e, but high e=h because octaves are fun black keys are in 1-6, in order from lowest in the octave to highest
tell me any songs you can play on one octave, I will put them up here with credit h-d-c-b-a...a-b-c-d-h-h-h...h-d-c-b-a...a-h-h-a-a
