Use your iPhone/iPod/iPad with Max/MSP or Pure Data! Fantastick turns your device to a custom multitouch controller. Send multitouch data to the host program and receive drawing commands. Instead of a limited set of builtin-widgets, the interface logic resides in Max/MSP and only drawing commands are sent to the device. Build interfaces that. work and look exactly the way you want. change dynamically to fit the musical context. are experimental and would not be possible with other apps.
