Hi Tony,
Rog says that Sandisk 1gig cards work well and as I have just had an email from Amazon offering these from £4.45 each I may just have to find out for myself.
I read something that said 2gig cards will not work with Technics keyboards - I wonder if anyone has got one going.
Still love my KN2600 1 year on, and far prefer it to the Tyros 2 I have to use at work sometimes!
Cheers,
s.
