Saba,
Here you go fella. Here are some samples for ya.

I started off with a well known riff dry using the virus patch called "Not Easy SV" and applied effects through the Lexicon. Each patch name is in the filename in the format:
EFFECT TYPE - PATCH NUMBER, PATCH NAME.mp3
Probably shouldn't say this as I guess I am about to give myself loads more work to do but I also have the TC Electroinics Powercore! This has Megaverb and Classic verb based on algorithms from the hardware reverb units. If you need samples of this in action (although it is not the unit you are talking about) then let me know. It will not be possible until next weekend though.
All the best,
Martyn
