OSC

Open Sound Control (OSC) is a protocol for communication among computers, sound synthesizers, and other multimedia devices. OSC's advantages include interoperability, accuracy and flexibility allowing for multiple commands to be sent simultaneously.

OSC offers real-time control of audio and other media processing devices while remaining both flexible and easy to implement.

Ctrl for iPad allows custom OSC strings to be produced and triggered from each control.

Furthermore, Ctrl for iPad features an OSC API (methods located under applicable control types) which allows the theme, state, label and more to be controlled remotely.
