Did you try doing a reset If my memory serves me right, you hold down the STORE button and power up.

>> any way im just curious if any one has ever seen or heard of this before, and what it might possibly be, i couldn't find a single thing about it online!
>> i love this synth, it have become my favorite one in the past couple of months, i would hate to see it die.
