So it won't play the corresponding root on the audio guitar to coincide with the bass part when you play a Bm7b5/A...assuming you change the split point to accommodate the chord?

This is when the keyboard is in On Bass, or bass inversion mode.

In other words, the lowest note in the Audio guitar part would be an A when playing a Bm7b5/A?

I'm not trying to make this confusing...I'm interested in how the Audio guitar parts handle on bass chords when they are played alone.

It would be nice to be able to play a chord progression with a descending bass line, using the guitar parts alone. I can do it on the S910.
