Virtual Instruments

Just wondering if anyone knows some good sites for free (not illegal) instruments such as guitar for use with computer music? I use Cubase SX so it needs to be compatable with that. Thanks

i know for a prog name HYDROGEN, its a drum emulating machine and you can export your song into .waw format. try it via google. or if you have fast link, you can try to find some torrents of grooveagent, virtual bassist or guitar pro 5, from which you can also export to .waw, and with real sounds turned on, it looks like real instruments. wish you luck ))
