The manual says:
To transpose a sequence up or down during playback:
1. Press the play button to hear the sequence.
2. Press a note on the keyboard above or below middle C. The sequence is
transposed to that key. (Middle C plays the sequence as recorded.) For
greater range, use the Transpose Up or Transpose Down buttons.
3. During playback, if you want to restart a sequence from step 1, press
the reset button.
However, the sequence restarts from step one when pressing a key. I would think there should be a setting to turn this on or off but I can't find such a setting?
