Hi - after the various notes about Registration issues (registrations not saving the settings right etc.), since I found I noticed it too, I decided to go through ALL of my Tyros5-originated Registrations again. I had already gone through them all in quite a bit of detail, to select newer sounds, make various adjustments, re-select Style to get new balance settings, and all seemed OK.
When I later noticed 1 or 2 didn't have the settings I saved, I saw all the notes on this topic. So anyway, I am about 3/4 through re-checking of my Registrations - checking every one of them again. I was pleasantly surprised that of 55 banks (file), of mostly 8 Reg's each, I only had 4 Registrations with a problem. The problems were always in the LEFT part. Usually the Effect was wrong (different than I had originally when I saved it). So that is maybe 400+ registrations I checked, and only 4 had a problem. So it's 1%, not really that bad. Still not desirable - but luckily 99% of my previous work was intact and OK. I made note of which 4, so I could go back and make sure the new changes "stayed" or "took".
I'm going to finish checking the remaining ~150-200 Reg's just in case ...
I'm at code level 1.30 (latest I could find).
