I may not know much about this stuff, being a guitarist, but for my clavinova electric piano, I bought a USB cable with two midi (five pin) plugs/ends on the other end, as the clavinova didn't have a USB. Worked as soon as I plugged it in. No software, nothing else needed. Hope this helps. This cord only cost $30 canadian so ask lots of questions before buying and you can always take it back.
Also just for your info, 'Native Instruments' company offer freebies as demos called 1)Kore player, 2)Compliation Vol 1.,and 3)Kore 2. The first gives amazing quality sounds and the 'player' - a software, the second gives another 100 sounds, and the third gives you (only in demo form, you can play with the stuff for 30 mins then stuff disappears, but you can record it) gives you about four hundred other sounds, the ability to split you keyboard and layer multiple sounds and you can tweak all the sounds included in all three, there being eight preset tweaks, so if you don't like a sound in preset A, try all the other seven. Some are great sounds. I'm now into keyboards like never before. The trick has worked on me though. Now I want to buy that, or logic express, or logic pro, so I can split my keyboard and keep all the settings and instruments. You should here my six year old play mission impossible with four double sounds on one keyboard. Like the real thing.
Hope the cord/lead thing helps, the other was for free. Makes the g'band sounds sound like toys, though they can be tweaked to be pretty good.
Enjoy musicking.Aidan.
