This program is a lot of fun! I enjoyed flying around the 3D piano keyboard array as the MIDI notes fell onto it like rain. Try it out!

Important note, though: Follow the Quick Start instructions above to pick MIDI Out from the Options menu and choose Port A = Apple DLS Music Device, or you won't hear any music.
