iOSC (App Store Link) is a remote control application that uses the OSC (Open Sound Control) protocol to turn your iPhone into a music control surface.

Using the OSC protocol over your device’s built-in Wi-Fi connection, iOSC communicates with other compatible hardware and software nodes on your network. You can also remote control the middleware such as Max MSP, Processing, ActionScript (FLOSC) and many other devices that support the OSC protocol from your iPhone.

It sells for $2.99.
