JMD,

In Song Settings, there is a setting that forces BIAB to use non-transposed Realtracks if they exist. Try this and see if it helps. You will need to regenerate the tracks after activating it. While you are in Song Settings, also try disabling "Natural Arrangements" for this particular song and see if that helps.

Most Realtracks are performed in 3 or 4 different keys (some are recorded in all 12 keys), and a Realtrack backing is obtained by using these saved performances to create the backing track. For example... If the Realtrack does not have a chord that is saved in the original key (for example C# major), then BIAB will take the closest saved chord to the key and transpose it to create the required chord. In the case of C# Major, it is possible that either a C or a D chord might be transposed to obtain it if it wasn't present in the original Realtrack recordings.

I've found that the Piano Realtracks are more sensitive than many other Realtracks when it comes to transposition and working outside the recommended tempos. For this reason, I often choose to use a Midi Supertrack (MST) with EZ keys rather than a Piano Realtrack. MSTs are much more versatile that Realtracks. The MSTs are created directly from Realtrack performances. When Realtrack is recorded, the information is directly converted to MIDI and the MST grows from there.

Just some thoughts that might be useful.
