A kludgy workaround to the problem
I had a Chord Track with a zillion chords in it that I really needed to transpose from Am to Em. Of course it ended being one that wouldn’t transpose at all. Not wanting to manually change a zillion chords one at a time (which would take slightly less than eternity ) I figured out a rather ugly but fairly simple way do it.
- Create a new Instrument or MIDI track.
- Select this new track
- In the menu “Project/Chord Track” run “Chords to MIDI” to create a new MIDI Part with your chords in it.
- In the track’s Inspector Chord Track tab, disable Follow Chord Track which was automatically enabled in step 3.
- Open this new MIDI Part in the Key Editor, ctrl-A to select all the notes and move them to be in the desired key.
- Delete all the chords in the Chord Track.
- With the MIDI Part selected, in the menu “Project/Chord Track” run “Make Chords”.
- The transposed chords should now be in the Chord Track.
You might want to save the project under another name before doing this, just in case.
