Thank you UD and MacAllcock for the response.

MacAllcock, like your SD1 my PRS2000 doesn't glitch, when both voices has the same effect.

So now I have set up a registration-bank with 8 of my favorite voices (with the same effect). And furthermore when I call up the bank, and press Edit, each voice can be given its name - so having this screan "on top" when playing, it's just to press the corresponding button next to the screen to select any of the 8 voices. Of course you can also hit the "normal" registration-buttons.

Thank you very much MacAllcock for guiding me on the right track.
