If you ever get Ken to do some more, what I thought would be good is some lead fills,
so if you hold all instruments and the same guitar with same FX plays a lead fill.
You would need to be able to generate a UT on the Util tracks and change the UserTrack to the same guitar but playing fills.

A good idea is any new ones get them to record DI also so when you change playing styles mid track the DI guitar will blend using the same added VSTFX.

You could also make another UserTrack that plays lead fills in the A and rhythm in the B.
The A UT can be made up with empty bars and bars with fills so it's not playing all the time.
