There is a new firmware available for the DTX-MULTI 12. Version 1.03 adds three significant improvements to the unit:
Added ability to route the CLICK ONLY ("ph2"=solo click) to the phones. In response to requests from professional drummers who do not want the M12 sounds mixed in with the click headphone feed.
Added new PAD TYPES for our newest trigger pads including KU100 trigger pedal
Expanded the GAIN setting range from between 0 and 64 to between 0 and 127.
