Most unfortunately, my newer files use a lot more after-the-MIDI sound modulation, so you only get half of the story if you pick up the MIDI file.
You miss wah-wah effects, stereo flanging, guitar grunging, and other neato things I've been adding lately.
With the older files though, I'm always happy when I see people use 'em so it's OK (I appreciate the little credit in the description; some people don't put it and just claim as their own).
