gave my much loved Kn2400 to one of my Grandchildren,bought a Yamaha PSR-S910,what a disapointment.6 days later sold it on Ebay...Now looking to go back to technics.I am looking for some information about a card system that is used for storage on the 2600 and to which I have absolutely no knowledge...need someone to explain to me what the card actually is ? like is it the same as one would use on a camera etc,or does it have to be specifically for Technics? your help would be appreciated as I am considering looking for a 2600 this time.
