Thanks - this is the best solution so far - I had forgotten about this.

Completely starting over loses the chord changes and song structure so that doesn't work with existing work. What I am looking for is a way to lock in certain frozen tracks (midi or RT) and keep looking for the best alternatives. It appears that frozen tracks are lost with the style changes? Another problem is that once you want to lock in a track a new style only puts parts in the normal used up locations? Being able to choose where the tracks load would help. Getting the right midi part is even more challenging.

Also the existing BiaB track names now seem obsolete when many styles for example use piano for guitar etc. Why not just have tracks 1,2 3 etc and let the user or BIAb fill in the blank? Possibly keep only drums and melody tracks because of their special features.

Love Biab and use it all the time. I know that I can do some of this with RB and or Sonar but prefer using BIAB as a music creation tool before going into a DAW. Still hoping for a really good midi/RT interface for picking styles and or instruments. With the size of the program growing this becomes more important with every upgrade.
