We are the music makers - producers?

I've not but if you're looking at using it for Reverbs I'd definitely recommend having another look at the built in Space Designer in Logic. I never thought much of it until I started loading the absolutely enormous presets - the cathedrals and the prison hallways and the like - and tweaking those to fit. Now everything I make sounds like a blocked ear. Brilliant.

Ha, yeah, it's quite impressive. You can get some interesting effects from the PlatinumVerb as well.
