I found that removing a Realtrack always was kind of quirky with any BIAB version. The way i do it is usually choose 'No Realtrack' from the right click menu on select realtrack. Then erase eventual midi data left behind, Track Actions, 'Erase .. '. After that the track is usually set free. But if you want to add a miditrack from elsewhere you can only do that in the Melody or Soloist tracks; right click 'Open Specials' ...
