I have the set that came with my copy of Sonar HS a couple of years ago. I like the piano/keyboard/organ and bass guitars. However, the combinations used in the strings and woodwinds really are not applicable to my world of arrangement. It does come with a lot of what I call "Off road" sound effects. If you are super creative you may be able to use one or two. Again, I have not been able to fit them in my writing style.

As for working in BIAB, my experience says NO. There is something about the two companies that make it non-compatible with BIAB or RB for that matter. How I work it is create the music in BIAB, and export to Sonar and add any tweaking there whether to the existing MIDI tracks created in BIAB or add new ones in Sonar.

Hope that helps,
