Thanks for answering, Jazzmammal. I'm using Biab 2014 327 on an Intel Core7 PC, with 8 mb Ram and running Windows 7 Home. I've just made a "Return to factory settings" and the problem persist.

This is exactly what I'm doing:

1. New song, C chord on the first bar, 32 bars long, 3 choruses, any Realtracks style.
2. Click "Window" - "Practice window" - "Transpose songs" and set the "Each chorus a song is playing, transpose by # semitones" to 5.
3. Press play.

Now, Biab should play the first chorus in C, the second one in F and the third one in Bb, rigth?

Well, what actually happens is quite different:
A) the program plays correctly the first chorus in C
B) when the cursor arrives to bar 32:
-The playback stops
-The program correctly changes the C chord on the first bar for an F chord, which is showed for some seconds.
-The program then incorrectly changes the F chord for a B flat chord...
-But restart the playback playng on F!

By the way, I'm getting the same anomaly on the transition between the second and the third chorus.

So, I'm getting two problems using this feature:
1. The playback stops for several seconds between choruses, in an unmusical way (it's imposible playing along between choruses)
2. The program shows some (incorrectly transposed) chords, but plays the rigth one.


Is it working correctly for you?
