It is very good solution to synchronize mixer with Notation and PianoRoll. And I am impressed with other solutions! But what I found and what I lost:

1. I can select in mixer (and on top buttons) any track except THRU. Therefore I do not have a access to THRU track.

2. For selected track I can quickly set any patch from favorite list using Ctrl-Shift-1,2 ...9,0. For other instruments from bank I usually used Ctrl-Shift-(-) and Ctrl-Shift-(+). But now Ctrl-Shift-(-) decreases numbers by 2 and Ctrl-Shift-(+) does not work at all.

My best
