Cleverly named because it's a piano and cello. At least emulations of those timbres, but different in many other ways. Tracks 1-4 are played by emitter 1 controlled by MIDI channel 2 and emulate a stringed instrument. Aftertouch moves the emitters to the right and adds more overtones. All the way over, and they borrow a bit from track 5.

Track 5-6 are various piano-ish sounds played by the other emitters responding to MIDI channel 1. I designed this one to play a Webern piece. It was a bit of a failure, but it's still fun. If you have a MIDI keyboard with a split, you can have cello on one hand, and piano on the other.
