Just noticed the process to actually get to the key contacts may well be different to the Kurzweil, as from the photo showing the underside of the keybed of my Virus Indigo it appears there's a black plastic cage over the base of the keybed, along with springs on the rear.
Without cracking mine open again, I'm presently unsure of the best method of attack to get access to the key contacts themselves.
However if you have a look at it and find it's not intuitive, contact SynthesizerService (who are Access Virus' hardware branch).

They offered me excellent info about repotting, so hopefully they would respond similarly. They were a little slow, if I remember, though, so patience if needed.

A ribbon-controller or XY-Pad might be nice, too, please! Thanks!
