First when i was playing strings or hammond , during the play , sounds freezes ....and no matter what i touch it doesnt play anymore but the menu doesn;t freeze. i can change combi, prog , global or change the tone but that sound keeps hearing. It stops only when i shut down the keyboard. this happens at random ....i couldn.t find a pattern.
last week i cleaned up the rubber bands and the contacts on the contact board and it was fine for a day or 2. but then another thing happened , after a period of playing it didn't sound of what i was playing...it changed to some random notes.
beside this the sound blocks for seconds while i still play...like ure blocking a key.
anyone heard about this? any solution to this? or my keyboard it's simply possessed and needs an exorcisation

Thanks and sry for my english but im very intrigued because all happened all of a sudden
