TouchOSC is an iPhone/iPod Touch application that lets you send and receive Open Sound Control messages over a Wi-Fi network using the UDP protocol.
The application allows to remote control and receive feedback from software and hardware that implements the OSC protocol such as Pure Data, Max/MSP/Jitter, OSCulator, VDMX, Resolume Avenue 3, Plogue Bidule, Reaktor, Quartz Composer, vvvv and others.
The interface provides a number of different touch controls to send and receive messages:
– Rotary controls
– Push buttons
– Toggle buttons
– XY pads
It supports full multi-touch operation, five controls can be used at the same time. Additionally the program can send Accelerometer data. The application comes with five layouts that are organized in multiple pages. We are working on another version of this program with configurable layout and adjustable control behavior and value-range.
