I originally purchased the Yamaha MX-88 for use as a stage piano for visiting musicians. The Yamaha MX-88 is a Yamaha Motif with a crappier interface and MIDI implementation. The sound engine is identical and hackable.
Local Control
- Press [UTILITY] button
- Select “02:MIDI” by using the cursor [∧]/[∨] buttons
- Press [ENTER] button.
- Select “LocalCtrl” = “off” [ENTER].
Warning! When this instrument is used by itself and this parameter is set to off, no sound is produced even if you play the keyboard.
