Korg Poly800/EX800 Users

i have the polarity right, bcause it does power up, it is just that 
when i hit a note it changes pitch, and is very wobbly.  It might not 
be the adapter, it might just be my poly 800 is messed up.  but the 
batteries worked for the first 15 minutes, then i went to turn it 
back on an 30 min later, and the pitch wobble started back.
do you have any idea whats wrong?
thanks,
