Wrkit, I've been reading this thread again. Lets start over because this may simply be a misunderstanding of terms. You first refered to using the ACW as an audio to midi converter. It doesn't do that and this Yahoo group post doesn't change that. The ACW is primarily used for two things:

1. You're not a very good musician, you can barely count on your fingers and toes so you put in a favorite song you simply want to play yourself. It will give you more or less the layout and chord changes so you can figure out the rest of it. That function has nothing to do with Biab, converting anything to midi, none of that.

2. Here's where there might be a misunderstanding. If you send the ACW info to Biab all it's doing is populating the chord grid with what it thinks are the chords. If you were to take a pic of the chord grid with your camera, then click on file>new in Biab and then looking at the pic, manually enter those same chords into a new blank chord grid, what do you have? A brand new Biab song waiting for you to pick a style, set the part markers, etc. There's no audio to midi conversion happening. It's just the chords on the chord grid.

That's all this is. The ACW gives you the chords to a new Biab song so if your original audio song is a 6/8 jazz swing, you can then take the same song and use a country rock 4/4 shuffle or something. That's it. Conversly the ACW also puts the original audio file on the audio track inside Biab so you can find a style that fit's the original audio file and then generate some Biab parts to go along with it. If you don't want to play along with the original audio file you mute or delete it. Biab is not using the notes the ACW detected to somehow create or choose a style or anything. You simply pick any style you want as usual and Biab generates the parts. Again, nothing to do with audio to midi conversion or random chord generating. Now, I will admit sometimes it may sound or look like random chords because it didn't do a good job of detecting. There's already a bunch of tricks mentioned here to help with that including slowing down the tempo like that Yahoo post suggested.

If you're a good player with good ears then the ACW doesn't do much for you and that's why I don't use it much either. For me if there's some complicated song I want to put into Biab, I can usually find a midi file of it and it's all there. Biab and RB both do a pretty good job of detecting the chords from a midi file and usually the melody is there too so all you do is look at the lead sheet and it's already written out for you. The procedure with Biab is similar but much faster when you have a midi file of your song. Biab takes the midi and like the ACW, will detect the chords from it and put them on the chord grid. There's always a few you need to change but that's basically it.

Hope this clears this up a bit.
