    Why doesn't the auto accompaniment play on my Medeli Electronic Keyboard?
    • B
      Billy LambertAug 31, 2025
      If the auto accompaniment does not play back even when Sync is in standby and a key is pressed, it may be because you are playing keys in the right hand range of the keyboard. To start the accompaniment with Sync Start, make sure to play keys in the left-hand range.
