Feature:
Calling this system a Rompler is just flat wrong. It will indeed play back samples, all sorts of them, and it will sample on it's own, but under the hood the VAST system is incredibly diverse and powerful. Once you get your head around it, and get into the programming, even if just altering patches and samples, you'll discover it's power. It's basically a digital modular synthesizer. The KDFX on it also adds to it's punch. If there is one thing that a computer, and most synths can't do, it's great reverbs - especially the early reflections and smooth long tails. Not so on the Kurz, the reverb adds to the perfection of the sounds. Where the Kurz looses some points is that modern synths can do almost as much, but often in much easier ways, and unique ways.

Quality:
At the time these were released, Kurzweil had the reputation of being one of, if not the, premier manufacturers of musical equipment in the world. The highest quality and builds were put into it. I don't gig with it, and it's a bit heavy, but I also don't fear it will break or let me down in any way. I should also note here that they keys on this synth are just superb. It has one of the best feeling sets I've ever played.

Value:
This is hard to say. If you're looking for a powerful workstation that sounds great, better than computer based synths, or comparable workstations (Korg Triton Extreme, Roland Fantom) then the cost is certainly worth it. But you had better know what you're buying before you lay down the cash.

Desirability:
I'm not sure how to answer this. I own a Waldorf Q, and that looks cool with all it's knobs and such. The Kurz looks more sleek, like a Koenigsegg CCX. You'll look at it, and while there's nothing outwardly fancy about it (compared to, say, a Ferrari Enzo?), it looks pretty slick, like it will do a lot.

Sound:
While this is getting to be an older synth, it's sound is still unparalleled. There's something in the purity of the samples, the partials, oscillators, and especially in the very powerful KDFX signal processing that makes this the kind of workstation where every sound coming out if it is superb, all the way across the board.

Ease of Use:
Getting it to sound great isn't a problem. There's thousands of patches and samples out there to get going. And once you start trying to tweak it, you'll get going and make good use out of it. But I knock it a few points because really getting into VAST and programming, especially on a relatively small screen by today's standards, is going to frustrate some people. It still frustrates me, and I've owned it for three years.

Support:
Never once needed any service, so I can't say. I am knocking it a point because Kurzweil has been bought and sold now a few times and are going through a period of trying to structure themselves for the future, so it's hard to say what will happen if you made the call to them.

Overall:
I'm sure this synth will keep me happy and be a centerpiece of my studio, for some years. Mostly because it just sounds so impressive and is such a workhorse. Until it's replaced with something more powerful and easier to use (such as the Korg Oasys - though I don't care for the Korg sound - a very subjective opinion, the Oasys is more powerful, and easier to use).

I have aranged and conducted for Easy Listening syndication for many years. Until now, I felt the strings produced by even the finest keyboards were hideous! I have never heard anything like this machine! All of the orchestral sounds are perfect! I honestly can't tell the differece between a score recorded with a 50 piece orchestra and done with this Kurzweil. Even the subtle sound of a pluck or a breath can be integrated! A must have!!
