For general troubleshooting of the Grandmother, we recommend the following steps in order:
- Reset all GLOBAL SETTINGS
- Hold down the HOLD and SYNC buttons for three seconds until you see the SYNC button blinking.
- Hold the highest black key (A#2), and while holding it press the lowest black key (F#0). You will see the three buttons on the LHC blink rapidly for a moment to confirm that the reset happened.
