I also liked Technics, and thought it was ahead of the times.
The KN-7000 was quite a keyboard, although I wasn't crazy about the sunken key bed.(Sorry Trevor, I disagree with your keybase opinion)
I also never liked the file structure of Technics keyboards, example, recorded songs were a default save as a Technics File rather than a midi.
Trevor, Not sure if I agree about the big band sounds, but one thing is for sure, you can explore many third party styles and sounds for your Yamaha T-2, and I'm sure you could find suitable big band sounds. Your Technics KN-7000 is limited in obtaining new stuff when they decided to suddenly throw us all overboard without a life jacket.
That being said, I miss the KN-7000, and would even settle for my ol' KN-3000 to mess around with. Loved the sax and organ sounds.
