You're welcome... I think ...I mean, I'm sorry to hear yours is the same. I took mine to Three Wave Music here in New Jersey (http://threewavemusic.com/), and (two weeks later) the owner said a propietary chip - of which there is no replacement - has failed.
The keyboard is otherwise near mint. In fact, I knew the owner of the store where it was purchased, and - being aware of subtle differences in keybed feel - was allowed to "try before I buy". This one had the best action by far. Still does.
It makes a great controller - with aftertouch - for my K1r. But not enough at this point to justify hanging on to it. I have a feeling it's destined for eBay as a "Parts, not working" auction. Or back to Three Wave, as they offered to buy it for parts.
If you ever find a solution, don't hesitate to post! Thanks!
