Andrew:
Just for the record I'm happy with the upgrade and the price. I believe the additions were worth the $99 I spent. (Well actually, closer to $300 because I sprang for the upgrades for Breverb and TH2.)
Which leads me to my question, do you know if there is a discounted upgrade price for the full version of R-MIX? As I said, it's one of my favorite new additions to the X2 upgrade and I think I could really benefit from the full version.
Thanks again to everyone who worked so hard to make X2 a great upgrade!
