I haven't been able to figure CoolEdit out that well, but I haven't exactly tried, and the documentation looks ok at first glance. I haven't tried N-Track either, so can't say if it's more complicated or not.

I use cakewalk the most, for both midi and audio, and I love the reverb settings, too! The only thing I like better is FruityLoops' reverb plugin, it really does sound like a "good room" if you just use a touch and make it warm. Too bad cakewalk doesn't load fruity's plugins... sigh.
