1. When AUTO MODE is active and COMPOSE ALL is selected then both melody and harmony will be autocomposed every 4 cycles. The text below button PLAY will show "AUTO ALL".

2. When AUTO MODE is active and COMPOSE NOTES is selected then melody only will be autocomposed every 4 cycles. The text below button PLAY will show "AUTO NOTES".

3. When AUTO MODE is active and COMPOSE CHORDS is selected then harmony only will be autocomposed every 4 cycles. The text below button PLAY will show "AUTO CHORDS".
