I found out that Chuck can receive OSC events, with the help of my roommate Max Praglin. I found a free iPhone app, called Control, that lets you send OSC events to a computer using the Internet. Going off the material online (and with a little bit of inspiration from Michael Berger) I wrote code to take advantage of this.
Both Chuck files use the iPhone accelerometer as a control mechanism for playing something called the "Amen Break", a 4-bar drum break from the song "Amen, Brother" by The Winstons. The song was not popular, but the drum break has been used in many other songs (including "Straight Outta Compton" by NWA, many underground British drum-n-bass tracks, and countless commercials).
The first file, "notes_full.ck", uses X and Y directions to play notes from a 2-octave C major scale. Which note is chosen is based on the direction the iPhone is traveling, and how fast. In addition, sudden movements on the Z axis start or stop the drum beat mentioned before.
The second, "chop.ck", is somewhat simpler. It uses the X, Y, and Z motion of the iPhone to choose where to sample from the drum break. Given how much the break has been sampled by others, I felt this was appropriate.
