It sounds much better now. My only beef with it now is that it's so repetitive, but definitely a great start. I'd like to hear a cool Scherzo section or something. For an example, listen to 600 AD In Piano by kLuTz from OC Remix, or from his site
http://klutz.vgmidi.com/music.phpAnd by the way, my system (and every other one I've used midi on) tends to default to the Microsoft Midi Mapper, which uses the GM sounds, as opposed to the Microsoft GS Wavetable SW Synth. Nearly every midi program ever made will default to the midi mapper before the wavetable synth.
I've used computers with Audigy, Live! and my current one running an AC'97 onboard. All of them defaulted to the midi mapper first. You had the option to use the wavetable snyth, but from my experience, it had terrible lag when you played anything with a keyboard, so I tended to keep away. Now I almost exclusively work with VSTi's and ASIO to eliminate as much lag as possible.
