If when pressed it played the first beat in the next bar then stopped that would be the answer."
Bazz, You can do just that
You can stop the style playing on any beat of the bar by just pressing the 'Start/Stop' button at the right time........ If you press immediately after the First beat has played, then the rhythm will stop after the First beat - the style then resets to start on Beat 1 of the bar, next time you play a chord or note below the split point.
It's best to use your left hand for pressing the Stop button, that way, you don't get a left hand chord 'hanging' over the break.
