I'm happy to report that the Tyros 4 1.02 OS Update appears to have addressed and corrected the sudden Rt voice volume drop and style part volume save problems I was previously experincing. No other problems to report (so far) on my end.

I'm of course anxious to learn whether Chony's "still" experiencing his YouTube #3 and #4 outlined problems anymore as well. Chony, please let us know. Thanks.
