An update to my previous reply the 2496 card is great for audio, and has great drivers and will work with win 7, but it does not do midi. If your Win 7 is 64 bit, you can use a hardware midi device such as ketron or use the coyote Forte soft synth for about $40. You can also use sound fonts which are triggered by midi if you don't like the midi sounds built into your mother board.
