PatchMaster is a MIDI processing and patching system. It allows a musician to reconfigure a MIDI setup instantaneously and modify the MIDI data in real time.

With PatchMaster a performer can split controlling keyboards, layer MIDI channels, transpose them, send program changes and System Exclusive messages, limit controller and velocity values, and much more. At the stomp of a foot switch (or any other MIDI event), an entire MIDI system can be totally reconfigured.

PatchMaster is totall programmable using Ruby. See the examples for a few ideas.
