- Enter Master Menu.
- Navigate to the 'Send MIDI Data' screen.
- Select 'Master Settings' to transmit.
- To restore factory defaults, one would typically perform a MIDI System Exclusive dump of the Factory data back into the unit, or use the 'Factory Settings' option in Beats Mode (for Beats only). The manual describes transmitting 'Factory Presets' and 'Master Settings' via MIDI.
Note: The manual specifically details how to Send Master Settings (page 30). To reset the unit, receive the Factory Presets/Master Settings dump from a sequencer or another unit.
