The MIDI Options screen allows selection of a MIDI Device and definition of MIDI Mapping Tables.  A MIDI Mapping Table assigns MIDI Signals (sent from a MIDI Device when keys are pressed, knobs turned, sliders moved, etc.) to Liquib Actions.  Multiple MIDI Mapping Files can be created and saved, making it possible to create customized Mapping Tables that might refer to sets of Images, Scripts and Music to be used during art performances.

A MIDI Playing Output Device can be selected to receive MIDI Signals when the Enable MIDI Playing option is activated.  Typically, this might be the Microsoft GS Wavetable Synth, which is included with all versions of Windows.
