Anyway folks back up and running!! opened up the synth and had a good look around, checked all connections from voice / psu / processor board.... for a split second even thought that the? 68b09 chip might be the culprit as its known to be a cause of mem corruption although not as common as you might think.... the 6116's looked fine some newer than others but no visual defects, its actually a very tidy synth on the inside... closed her back up and done a hard mem reset (sure nothing to lose except my mind) haha...? power cycled and back into the diagnostics page, ran all the tests and tuning protocols.. five pass's! and still have my patches.... i am going to back them up again this week... cause that's nearly fifteen years of programming going on there! what a synth! so organic! i swear there's blood running though it! - Happy Irish GuY??? :)))
