I used Native Instruments Bandstand for mine.
I just did a little research on NI Bandstand, and I must say, it looks like a fairly nice piece of software

2.5 GB of samples? That's not bad

.
I'd be interested, except I recently got a version of Eastwest's
Colossus, which is a similar idea, except more techno sounds, full GM compatability (just like Bandstand), more guitars, pop brass, and more percussion kits. 32 GB

Still, NI Bandstand is a nice bit of software. Sounds far, Far better than any MIDI instruments on any sound card or soundfont I've ever seen (I checked out some of the demo MP3s from Bandstand). Good stuff
