Although I never have heard any of the exspansion boards, they never did appeal to me.

It seems to me that the 7K is so very versitile. I like to "tweak the sounds in the styles, and "tweak" the sounds in the sounds.... Additionally, I have music from others who play the 7K and it is fun to listen & try to figure out what sounds and styles they use.

The 7K is my 5th Technics KN.... I already knew the "program" of "creating" additional products for owners to purchase....

All of you have confirmed what I had figured out without buying the expansion boards myself.... )
