The Remapper tool lets you map incoming MIDI input to a specific scale. The scale being mapped-to is controlled by the global variable Mapto, whose value should be the name of a scale in the Scales array (e.g. "newage" or "fifths" or "ionian" or "dorian" or ...). The key of the scale is controlled by the global variable Key, which should be a single note (e.g. 'c', 'a', 'e-', ...).

The GUI interface to this tool lets you set the MIDI channel that will be remapped, and lets you turn the mapping on and off.
