seriously the only "complaint" I have is, the red GUI. this is all!.....the layout, is VERY easy to understand. the patches alone sound as real as you could ever want/need, because of the way they were sampled FROM real instruments...but then you throw in all the effects you can change/add........oh mama!!!! this plug-in, is the very first one I go to when I start a project. You might find yourself just playing for hours live, and actually not completing any tracks...lol for the money, the presets you get, and more importantly, instant realistic sounds.........its worth every penny.
