Btw,

forgot to mention that this tread here at SZ have lots of useful info:
http://www.synthzone.com/ubbs/Forum25/HTML/004145.html

Read the info from "technicsplayer" (Alec Pagida) carefully. What he don't
know about the Technics KN's are not worth knowing.
Hopefully your problem are caused by a faulty update, and will be cured by
a new update?

There is already written some treads about the update issue, so maybe you'll
find some useful tips in other posts too.

Again, good luck.
