Gary thanks for your post.

Do other PSR3000 owners who used to own the PSR2100/2000 notice that the organ flute volumes are too low?

OK, so if you want to go from a break to a variation, you have to choose any variation but the one you're working with. This is different from the PSR2000/2100 and probably the Tyros. I consider this to be a glitch.

So you can't go from ending 2 to ending 3 or ending 3 to ending 2. This is also different from past keyboards. The workaround, we now know thanks to Gary, is: If you accidentally pressed ending 3 and want to change to ending 2, press ending 1 first and then immediately press ending 2.

Thanks Gary
