O.U.I. app for iPhone and iPad

OUI - the OSC (Open Sound Control) User Interface. Unlike other OSC controllers, OUI provides a dynamic multi-touch interface that does not need an external editor. Interfaces for OUI can be created through the use of OSC messages (described on the last section of this About page) or directly on your iPhone or iPad when your interface is placed into edit mode. OUI uses a wireless network connection to send control values to any client application that can listen for OSC. Many common sound environment provide the ability to listen for OSC messages, including the SuperCollider programming language, PureData and other proprietary music and sound creation environments. Since communication is network based, OUI can be used on a local area network (LAN) or even to communicate with OSC clients around the world.
