Just for a little update, I downloaded the demo to try out. Made a quick version of a Chevelle song to test it out on with Logic Pro X, utilizing logics drummer. I used the Renaissance on the Kick on a parallel bus and did the same on a parallel bass guitar bus, handling the low end. Made a pretty heavenly dramatic difference, and was quite easy. I wish I had been in the know when this plugin was given away, but in any case i think it may be worth the $39, so i think ill give it a shot.
This is actually the first aftermarket plugin I will have purchased. the only other ones I have other than stock are the Focusrite Red plugins that came bundled with my Saffire 18i8. I rarely use them.
