Bob, When using the STS settings with the light flashing you are subject to waiting until the style finishes the measure. I do see your point: the style changes at the end of the measure but you want the new instrument to play immediately so you can play over the change.

Technics:
1-You can set up a panel memory to change instrumentation without a style change.
2-You can set up a panel memory (Extended) which will change the instruments and style.

You can accomplish #1 by using the Performance on your Pa3x. I shut off the Blinking STS light and select from the 4 STS settings -- or from the performance.

Did the Technics STS settings change instruments immediately when you went to the next variation or did that wait for the next measure?

I still believe in setting up at least 8 different full band sounds in the panel memory (Technics) or in performance (Korg) just to get a different feel in a song.
