HI, Zafarul:

If you can use a soldering iron, a midi cable is no trouble.

You need two 5-pin DIN plugs and a length of two-wire, twisted-pair cable - make it as long as you need up to 50 feet.

I'm not at my own computer at the moment, but as I recall, the pin-out, looking at the 5-pin DIN with its "plug-in" end toward you is: 1: no connection; 2: midi out; 3: no connection (sometimes ground); 4: midi in; 5: no connection.

In other words, just solder the two-wire cable to the 2nd and 4th pins on the DIN plugs. Don't cross them: pin 2 at one end goes to the same pin at the other.

As I say, I'm not at my own computer at the moment, so I'm not quite certain on the pin-out above, but troll around on the web a bit (Google will find it for you) and you'll find lots more information. My own system, which connects quite a few synths and samplers, has about 50% commercial and 50% home-made cables.

Good luck

David
