If you just want to finish a song, and the bass is the only thing that's misbehaving, you can:

  1. Save the file under another name;
  2. Freeze all the tracks except the bass; and
  3. Simplify the chords until the bass behaves.

It's probably not the best solution, but it'll get the song finished.

Vocal control, you say. Never heard of it. Is that some kind of ProTools thing?
