Ok...
We have 3 types of chord tracks.
1 - the most basic without key switches
2 - Now you can preserve keyswitches for particular VSTs
3 - Static Chord track. The one you can generate on track level, but
which is on different track from the one specified in properies.
This one will generate chord sheet once, but will not pick up new changes
automatically.

Each of these has its own benefits. When I export project MIDI, I usually end up with
At least 2 chord. Tracks.

I think the most reasonable solution is to be able to save Chord Track on the mixer
track level-right click. Just as we can save tracks as individual Wav files through mixer menu.
