Hi Arnie,
I thought you might like to know that I had this Americana SD Card bought for me by my family for Christmas and although I haven't tried all that is offered on it yet, I have tried all the CUSTOMS and the PADS which can be found at the end of the Folders and they are brilliant particularly the Jazz Pads. Tonight I have been trying some of the Country styles offered and whilst some I already have on Technics Floppies, they do sound better on the KN7000. The write-up on this SD card in my TechPlus magazine does state that it has been produced specially for the KN7000 and KN2600 so you should be able to use it on your KN2600 without problems.
I must admit it is very expensive in England selling at £99.00 (about $198 I think) hence the reason the family got together to buy it for me, bless em!
Yes! it is well worth having.
Hope this helps.
