Korg DW8000, Mono/Poly, MS-20...

Hi all

I've just purhased a DW-8000 -what a great synth.

However I have a small problem -when hitting a key I hear a small
"click", just before the actual sound is outputted.

Have anyone else had this problem and is it something that can be
fixed (I'm good at soldering :-) )

Thanks in advance,
Hjulskov
