Hi. all. I was given a Yamaha sy22 for christmas. I know its old, but was wondering if anyone knew how to help me get in running through midi into windows Xp on my system.

I can play it but it comes through the headphones only at this time. Im new to this art so some assistance would be appreciated please.
My specs are:

Athlon Xp 2000+
VIA 266A MB
Seagate HD
Windows XP Pro
Soundblaster
