How does this work?
The play midi key block plays the note for the given piano key. Piano keys are numbered from lowest to highest, counting both white and black keys. Middle C is always 60. The lowest key on an 88 key piano is 21 and the highest is 108. MIDI (musical instrument digital interface) is an industry standard created to control keyboards and other electronic instruments.
