hi,how do I set BB so that it will play the chords exactly as written? (i.e. with no extensions or alterations)



It never has and it's doubtful it ever will, that's not it's function. It's designed to be very flexible in creating backing tracks and tries to duplicate what real players would do by giving you a slightly different version of the chords every time you hit play. The styles control this as well as the "simplify chords" function. I've never gotten into creating my own styles but I believe you can open up the offending style and tell it what chord types to play, then save it as a renamed user style. When you open up a style, you see how it works. You assign "weighting" to different chords and that's where the beauty of the program lies.
Or, this is yet another one of the many reasons you should start using Real Band because one answer to your question has always been to export the tracks to a sequencer and there you can edit the chords in midi using the piano roll. But Real Band creates Biab tracks too so you're already in a world class midi editor. You can open up that track and change the note to take out that #9 or whatever it is. If you really like the whole style but it's just that one note, this is what I would do. Still, you're now only using Biab/RB to create a static sequence and you're losing all the flexibility. The really cool thing about RB is it lets you recreate that one track using a different style from the others. That means if you like the arrangement but the piano or guitar is the offending track that's giving you those chords you don't like but all the other tracks are good, you can audition every style there is for that one track until you find one that gives you the right chords. It could be a latin rock style is great for the overall feel the but a country style gives you the piano part you need. In RB you can literally have a different style for each instrument, a different style for the bridge vs the verse, vs the solo, vs the ending or whatever. You've got 48 tracks, go crazy with them. When you think about that for a minute, you begin to realize the incredible creative possibilities here. With all those instruments and tracks you still have all the neat Biab stuff, you can change the chords, rearrange the whole song if you want yet all those different style tracks will get regenerated to give you a whole new thing.
