Sick Korg

[Halloween Jack]

Well, I was all excited when I got my Atari ST in the mail, ran to my
nearest music shop and picked up extra MIDI cords and all... Had
everything all nice and set up, TR-707 synched to the ST, then out put
to my Akai AX-80 and thru to my Korg Poly-800. Everything was running
fine, until a little into it, I found my Korg wasn't playing. I right
away stopped everything, and tried out the Korg, nothing but noise
clicks. I thought perhaps the patch got reset. Started playing around
the settings, but nothing. Played with the MIDI channels and here where
it gets weird, the display went way past the regular 16 channels, and
further into hex numbers. I disconnected everything, and took it into my
workshop, and then plugged it into my guitar amp. Still nothing. So,
instead of cracking it open and poking around, I thought I'd ask here
first. Only thing I've thought of so far is opening it up and removing
the internal battery, then putting it back in. Any other solutions?
Anyone else have this problem? Thanks!
