Normaly every soundcard supports midi in and midi out. To get your soundcard ready for midi you need a special cable that will be connected to the Joystick port . This cable will have then 2 DIN connecters (midi in /midi out)and one for the Joystick.
Most Computer store will have these typ of cables. In Switzerland it cost about Fr.20.-.
I do not know your Synthesizer so i can not tell anything about your driver question.
