Greetings.

I own a Poly-800mkII and, as of lately, I've been having a problem with it. Basically, after it's been playing for a while, it will detune quite a bit (enough to mess up a song pretty badly) and make some noise. Both the detune and noise levels are always set to zero. If anyone has any ideas on what this could be and/or how to fix it, I would much appreciate it.

Also, I'm looking for a sysex file, or (preferably) a Unisyn profile for the Poly-800ii. Unisyn has a profile for the Poly-800, but not for the mkII for some reason.

Thanks
