Hi Jim, The KN2600 has the same storage system as the KN7000 and uses an SD Card (Secure Digital) for saving KN2600 format files and also MIDI files and MP3 files. This is probably the most popular of all the Digital Memory cards and you can use virtually any make of SD Card up to a capacity of 1 Gigabyte. However, since there are a few poorer quality 'Unbranded' versions of these cards - which may or may not work properly - I would recommend that you stick to the better known brands such as Panasonic, Sandisk, Kingston, Toshiba, Fuji etc. There are numerous sources of supply of SD Cards on the Internet, at very reasonable prices. One example is
www.7dayshop.com/ if you are in UK......
Within the range of SD cards, there are several different types and sizes. Don't be tempted to buy the SD-HC or ULTRA versions since they will not work on the KN2600. It is possible to use SD Cards with a capacity of 2Gb but this is a bit of a waste, since the KN2600 will only see the card as a 1Gb device, due to its addressing capabilty.
There are also three different physical sizes of SD Card - Standard, Mini and Micro. The KN2600 is designed to use the Standard sized card - which is about the size of a postage stamp - however, you can also use the Micro size which fits inside an adapter and 'converts' it to a standard size. The Mini size can also be used in conjunction with a suitable adapter. The Micro size cards are often cheaper than the standard size, due to their popular use in mobile phones.
Storing data from the KN2600 on the SD Cards is very straightforward and is similar to that using the Floppy Disk, which you had on your KN2400. Saving and Loading operations to the card, are much faster and of course can store much more data than a Floppy Disk. Using the SD Card system, will be fairly well covered in the KN2600 Instruction Manual.
