Interesting, Eileen. I thought someone had written a long time ago that Yamaha looks over the forums once in a while for product feedback. This is where all the issues are posted, other than people wanting tech advice.
When I updated the software from the initial release to the 2.02 (if that's the right number), my registrations all displayed the wrong knob and slider settings after selecting any registration. Prior to the update, any selected registration displayed the mixer levels, so that during a show, I had access to all those settings without having to toggle through the options to find it. Now, I must turn the Genos on, select the correct settings I want in the display, and then press the Freeze button. I know it's not a big deal but it should have not been affected in the first place. I posted the problem a while back and no one on the forum could answer why this happened. It seems to me that those display settings need to be stored with the Registration, otherwise Yamaha's default screen is displayed.
As for registration transfers, yes, they come across very well from old to new keyboards, but I find I must go through and check every one of them to make sure legacy voices haven't been selected, the levels are correct, and the effects sound right. These things all need to be checked because when they release a new keyboard, the sound processor seems to get an upgrade as well. This is a good thing but all of a sudden you may find your voices are booming out there too loud, where on the previous keyboard they were fine. Of course, you may only notice this when you're using professional speakers in front of big crowds and in big halls.
Transferring of registrations has never been cut and dry for me at least. I've always had to go in and check each one to make sure nothing has gone amiss. It happens more often then you think. It's very embarrassing to have this happen with a full dance floor!
