I would be quite curious to hear that piece.
We at CatSynth would be remiss if we did not post this holiday offering from Keyboard Cat, (i.e., chuckieart at YouTube).

By the way, they are not joking, you can download this holiday extravaganza from iTunes.

“Maceo looks at the notes.”
I believe the keyboard is a Yamaha CP-33.

Also, check out recoilsun’s bandcamp, featuring music with this Buchla setup. Interesting and meditative. Not sure if the cat assisted.

“http://www.playhimoffkeyboardcat.com – Keyboard Cat went to Hollywood and made a commercial for Wonderful Pistachios! Bento even met Perez Hilton and Rod Blagojevich! Get crackin!”
Really, Rod Blagojevich?!
Also on matrixsynth. The keyboard in this case is the classic Ensoniq Mirage.
