haven't got a PR in front of me at the moment but on the KN if you have Rhythm ON in the Panel Memory Expand Filter I save the Synchro ON in the next panel memory. Thus after pressing Stop for the break the next panel memory can activate the synchro again ready for the start chord as an alternative method. Naturally you can maintain the right hand voice across the two panel setups if you wish, but it gives you the opportunity to start a new variation after the break at the same time if the arrangement justifies it.
