I think Anthony's point is that he believes all keyboards should be somewhat compatible with each other. Am I correct in that assumption Anthony ? At least that is what I have deciphered in your posts...and if that's the case, I afree with you.

There are very few products that I know of that are NOT backward compatible.
Heck..I have a VCR from 1987 that can play tapes made in 2003, but that did not stop me from purchacing the latest model

I have a CD Player made in 1990 that will play CD'S made today, but that did not stop me from purchacing the latest model.

My Uncle has a piano player made in 1938 that will play piano rolls made today, but that is not stopping him from purchacing a new piano.

There are probably good reasons why Technics keyboards are not backward compatible...I just don't know what those reasons are.
