Hi all to all of you Polylovers,

Could someone give your expertise on this MK 800II problem?  (I think I´ve e heard about it previously..) Whenever I put a little extra pressure on keys or even press the case down, I get pitch bends problems. The synth seems to get crazy. I have checked the board and everything seems fine: nothing burned or wierd.

I am not using the original power supply, but an universal power source switched to 9V 300mah. Anyways seems to have some connection problems as sometimes it turn off with a lot of popping sound. Any relation to my pitch problems?

Thanks a lot for your advice!
