I can't figure out whats causing this and it makes it unusable because if you press the keys to hard it shifts pitch, or if you use it with a strap it moves around and that causes it to happen.UPDATE: Just tried adjusting VR1 and seeing if anything is pushing on it and it doesnt seem to be. I got it in tune but the problem makes it go out of tune. And it keeps it out of tune where it left if you turn it off then on again, so it wont reset back to normal pitch. If you pull the case up instead of pushing down it can make the pith go down a bit too. Could something attached to the case like the tuning pot be at fault? Im pretty sure its not the joystick playing up either.Any help is HUGELY appreciated.If I cant fix this do you think someone more experienced with synths or electronics could for me?Thanks!On Wed, Dec 18, 2013 at 5:00 PM, william greig <wilzgreig@...> wrote:Thank you I will have a look inside!

controling whole pitch of poly800
maybee this causes the problem?
but be careful because when you set it too low, it resets whole poly 800 and erases all of your presets.
