I've been grasping at straws for days now trying to figure this out and I figured by now I'd know what I was doing wrong.

Occasionally I would like to use BIAB to generate some solos for the solo-sections of the play-along CD's that I own. Most of these play-along's are from the Hal Leonard group -- Each of my books contain sheet music for a dozen or so jazz tunes and each book also contains a play-along CD with the backing tunes in MP3 format.

In a nutshell, I would like to be able to pull the MP3 in as an audio file (I've been using Audio Chord Wizard to do this), then pass this to BIAB where I could then instruct the soloist to create various instrument solos (one at a time) at a certain bar, for so many bars. I figured this would be great because I could listen to the solos one after another (picking a different instrument each time) and then finally choose the best solo arrangement (or combine different notation from one or more of these solos). I then just print the sheet music for my soloist instrument (i.e. trumpet, guitar, piano) and away I go! This is ideal because it lets me hear the solos against my backing track -- I could just type in my chords, set the style and let the program go, but then I don't get to hear the solo against my backing track. Also, I don't improvise well with piano and guitar and so, I actually do need more than the basic chord progressions to work from (the improved solo chords in my sheet music).

So, I thought that this would be pretty straight forward, but here's what is going on as best as I can explain it:

1. I'll pick a play-along tune.
2. The tune is in the key of: C and I want to solo for trumpet (B-flat instrument).
3. I use Audio Chord Wizard to pull in my MP3. Everything goes as planned and I send it to BIAB.
4. I test play it back in BIAB and sounds / looks good. BIAB notation shows I'm in the key of C.
5. Let's say that my solo needs to start off with the note - Middle C.

(at this point, when I play from my Hal Leonard book the MP3 is playing back fine and I'm in tune -- no problem). However ...

6. If I go into editable notation and insert a Middle C and play the note back, although it sounds okay (between my horn and the backing track), and it looks okay (my notation), when I have BIAB play the note however, it appears to be consistently off somehow -- I want a to hear my PC playing the note - C against the audio track (my backing track), but it seems like it's tone is a B-flat.

I can't change the key -- throws everything off. Can't transcribe -- throws everything off. The only thing left I thought to do was to try to set the Audio Chord Wizard to adapt by setting the 'out of tune' feature before sending it to BIAB but all that does is change the key!

I'm lost! Thank you in advance. I'm not thinking straight about this.
