You can only go so far with achieving exact voicings, inversions etc. Biab is midi based but all the new Real Tracks/Drums have added a whole new dimension and a whole new level of confusion to this. First remember midi is midi and audio is audio. The RT/RD's are prerecorded audio files so what you hear is what you get. What is very cool is the fact that even though they are prerecorded Biab is still able to chop up the files according to your chords and they can be at different tempo's within certain ranges. Having said that, if the piano part for one measure is a Cm9 and you want a Cm11, it may or may not have that available to you. Since these files are recorded ahead of time I'm sure for the jazz stuff they try to put in as many of the upper extensions as they can but there's no way they can put in all the different ways to voice a Cm11. You have no control over that, all you can do is put in Cm11 in the chord grid. What will really mess with your head is the style has no control over the Real Tracks. The chord grid does but not the style. The new all RT styles are really just demo's to show you what certain combinations of RT's can sound like. If you load up one of the all RT jazz swing styles and decide to change the jazz guitar solo for a bluegrass fiddle RT, that's what you will get because that fiddle part is prerecorded.
Midi is different. Midi parts are completely controlled by the style, If you're using one of the jazz styles and you have "jazz up the chords" checked off then you will get lots of upper extensions but again you can't put in an exact voicing. The style determines that. You can create your own custom style that only uses certain voicings. The program is called "Band in a Box" and it designed to give you what it thinks are the appropriate chord voicings not necessarily what you think would sound best. Unfortunately, it's not called "Musical Director in a Box". Some of us wish it were. Very high level players design these voicings but of course a group of voicings for Green Dolphin may not be what you're looking for with Tunisia even though they could use the same style. You're correct in that for midi, not the RT's, you can put the file into Real Band and edit the piano part to achieve exact voicings or simply play them yourself on a midi keyboard controller. RT's are audio files, you can't edit those except for cutting and pasting.
