MIDI System Exclusive Messages

The Raster uses MIDI System Exclusive Messages to get and set configuration properties and state. The
following System Exclusive messages can be used to configure the Raster, read current configuration,
and access other functionality that is not available through standard MIDI messages (for example, saving
presets to internal memory). You can use these messages to write a custom editor or configure a MIDI
controller to control the Raster.

The basic format is the same for all messages:
