Hi,

Using Oliver Gannon's RT #549 that you mention above, I just set BIAB to the key of G and generated 16 bars of D7sus. What I found was...

1. If Natural arrangement is enabled or disabled and 'Force simple arrangement' is active, then D7sus then BIAB plays G-C-E on the guitar and D (mostly) or A (occasionally) in the bass. To me, this combination of bass and guitar sounds like Dsus9.

2. If 'Force simple arrangement' is not active, whether or not 'Natural Arrangement' is on or off, then BIAB plays G-C-D (mostly), G-C-E (sometimes) and C-E-B (not very often) over a D bass.

From what I can tell, Oliver Gannon is also only playing 3-note chords. This means that when a 7th chord (i.e. 4 notes) is used, a note has to be sacrificed. I imagine that this is a contributing factor to the outcome you are experiencing. With this in mind, if Dsus is used instead of D7sus, the 3-note chord Dsus plays correctly (D-G-A).

While this doesn't solve your problem, hopefully it gives a little more insight into what you're experiencing.

Regards,
Noel
