Thanks DC and Mario. The GR20 does have tuning built in, so I'll check it and do a reset. Just got to track down the manual which is no doubt downloadable on line. Also, I have some neat custom patches set up from 10 years ago, which I'd rather keep. Mario, I did just what you said and the bleed disappeared. I'm hoping the switch will sort itself out with a bit of use nonetheless. I'll also have a read of the DAW GR20 info. All good. A bit like Xmas. :-) It really was / is a fine piece of technology.
