User Interface - It looks like something from a Skinny Puppy video, or from Saw IV - "Jigsaw In Space". If "retro cool" is a meaningful combination of words to describe something, then Rez 2.0 is "future cool" looking. Ugo has reinvented simplicity and workflow, not to mention is helping bring back *sliders* as controllers with this update. A lot of features packed efficiently into a small space, this is how it should be done eh.
Sound - Considering it's a mono synth, unbelievable in a word. This is a slice of modern electronica, from dance to industrial, there is truly sounds here for everyone. It just sounds great, I could go on and on, but you just have to grab a copy and fire it up. If this were payware, it would cost $39.95+.
Features - Not a ton of features, but the ones it does have sure make it sing and dance. It's a mono synth, so that leaves just one oscillator and filter for the main body of the sound. It's got an LFO of course, and some overdrive, a rather complete phaser, and a stereo delay effect that all add up to more than a 2nd oscillator to my ears. Did I mention the arpeggiator ? Yep, it's got one, and while it's pretty basic, it's got a few features itself and works just fine.
Documentation - A small .pdf manual is included. While the manual is a bit small, it tells you what each control does, and come on, it's a freakin' mono synth people, even I can sorta program this one ha-ha.
Presets - 2 full .fxb banks, so that's what, 256 presets ? You simply can't go wrong here if you do electronic music at all.
Customer Support - Ugo is a pro/payware dev also, so he's got his customer support act together. He's a K-v-R reg, and he has his own website http://www.ugoaudio.com/ where you can reach him with questions, and/or grab demos of his payware plug-ins.
Value For Money - Is there an 11 score here ? Seriously, this is the one I nicknamed "Zebra Jr.", it would be at least $39.95 if not closer to twice that if it had 2 oscillators and was hyped to death.
Stability - I've never had a problem with it, low on cpu usage, fast to open. It is an SE creation, but like I've said in past reviews, if you're still having probs with SE stuff, it's most likely your computer at this point in time, cause the rest of us aren't having those probs anymore these days.
Final Notes - If every freeware synth was this good, there'd be almost no market for payware synths. If you didn't grab this V2.0 update, then you have officially missed the boat in 2006, go get it now, and thank Ugo in 2007.
