If you turn off “Set Remote Control Focus for VST Quick Controls” - the little button to the lower right of the Instrument on the VST Instruments panel - and make sure “Remote Control Focus follows Track Selection” on the drop down menu (upper right - same panel) is Off then Shift/Master will take you to the Track Quick Controls.
Switching the “focus” button on and off will instantly take you back and forth between Track and VST QCs.
