I haven't read the whole thread so sorry if it's already been said, but BiaB will certainly recognise most of these chords - just press shift+enter to listen. I can clearly hear those jazzy extensions.

Whether the particular MIDI or RT style will accommodate it, though, is another story, and I do sometimes find that I can't get the particular chord I want with the particular style I want, but I assume that PG Music do have limited time and resources so they probably don't bother recording a 7sus#5#9 for a pop RealTrack (or program it for a pop MIDI track).

When I can't get a fancy chord working on one of my bebop/modal/etc RealTracks, however, that can be frustrating!
