Got a USB stick stuck under the keys of my PA 4X.

I had a loose USB stick in the keyboard case. Somehow it lodged between the keys and the front of the keyboard.

When I tried to dislodge it, the stick dropped into the keybed. I called a Korg service center. They said it's not likely to cause a problem unless it gets under a key. Service center said the back would have to be removed to get it.

Did a whole gig with the stick in the bed. Didn't create any problems with keys that wouldn't depress.

Damn. Dumb.
