I do see what you are saying, but my point is, everything is difficult before you know how to do it. It is fairly easy to learn to move channels between the soloist and melody, and there for to Isolate a sing channel on one or other of the two editable channels. Yes, it might be nice to have the ability to edit and freeze the other tracks, but with just a little effort you can transfer the melody channels to the soloist or the soloist channels to the melody. If you learn to do this, you can put up to sixteen tracks on these two tracks you can move all but one channel to the melody and then edit the soloist, you can repeat the process with a different channel and isolate the next track and edit it.
