Wechselspieler is a tool for mapping motion data from a video stream onto sound events in the MIDI and OSC protocols. It features a GUI for easy selection of trigger regions in a video stream and mapping these to individual sound events. It supports various video input sources, such as Video4Linux devices, movie files, and FireWire cameras. As output, it supports ALSA based MIDI devices and the UDP based OSC (OpenSoundControl) protocol for integration with MIDI hard/software and OSC-capable software like PD, SuperCollider, and Max/MSP.

Release Notes: This release feature two main improvements. The MIDI output device is selectable if your machine has more than one (e.g. a USB device). The FireWire input code has been reactivated.
