A nice thing to do is to augment the Music Style Arranger by recording a bass chord accompaniment via the sequencer using the basic mode in APC, then you can just play the piano as a piano without worrying about triggering the harmonic accompaniment at all while you are actually playing. It is already there for you as part of your backing group. So you can, for example, keep the melody line going with your left hand while doing something fancy on top with your right. Or of course, vice versa. Anybody know the answer to my question on the PR604 and the break feature in synchro/break? Leo.
