One more thing to add.

I guess what I'm really trying to accomplish is to be able to use the RealTrack soloists similar to how the Melodist can generate melodies for specific parts. The RealTrack soloists sound better to me so I'd rather use them than using the Melodist.

If I use the Melodist to generate a melody for a specific part, then just add more choruses or use the Song Form builder to map out something like ABCABC, the melody I created for a part gets duplicated into each chorus.

If I use the RealTrack soloist to try and accomplish the same thing, that's when everything falls apart.
