being pressed on a MIDI keyboard, color bars are displayed

is on. The program also responds to pitch bend and mod wheel

MIDI co-processor card and a Ensoniq Mirage keyboard (5 octave,
attack and release velocity sensitive).

I'm planning on writing several more MIDI products. Coming
soon to a theater near you. Watch for them.
