FrankK- thanks for your response.
Maybe bb has a problem reconciling the overtone series with their relevant chord families. eg the A7 chord you mention with F#, B and G would actually be an A13th, where G+7th, B=9th and F#=13th. This fits into a II-V-I scenario in key of D, as in Bm7-A13-Dma7. this would be fine for a jazz bossa but could be uncomfortable in a rock/country song.
Substituting a 9th chord may work in some cases but the #11 (b5) may pose a problem. In a bossa situation a D9 would probably heading into a Dbma7.
The prob I am looking at is when the chords entered in the score come up with the incorrect samples or addresses, and it seems that others have experienced the same thing.
All this technology makes us lazy, which is fine by me if the flow is not slowed down.
