I'm trying to figure out how to apply a RealTrack instrument to each part of this type of midi song file but all the midi data is clumped together on the Melody track so there is no way for me to go in and just isolate the Bass or Drums and affect just those instruments by applying a RealTrack to them. It makes sense now that I understand that only the Melody and Soloist are user writable so it is not possible to select the Drum data and send it to "Drums" in Instruments and Parts because BIAB uses those and they are locked out.

Thank you for your help, now I'm seeing it.
