I just got one of these and I’m pretty fucking impressed.
One of the best user interfaces I’ve come across in a digital module with a screen and menu system.
The feature set/firmware is just perfect. Absolutely perfect.
Every feature solves a musical problem, nothing is wasted.

I've had Quadigy for nearly two years now, and it is the anchor for all things complex, sustained and evolving.
The UI is, as someone above stated, one of the best menu-driven digital module experiences out there.
To have four ADSR envelopes with such fine, detailed control and options in 14HP is amazing.

The new Klavis Quadigy has the most advanced control over shape/time I've seen in a envelope module, the interface is genius and the price very good.

The thing is an amazingly well designed workhorse.
I believe Eric (Klavis) said it was designed with the intent to be simple and accessible, and only more complex when you need it to be. In use, this becomes pretty obvious, it's a joy to use.
Tbh, I was a little worried when I ordered it because it really can do a staggering amount of things, but in reality, I think I've looked at the manual once, and that was just while I was waiting for it to arrive and it opened up loads of cool ideas and influenced my patching in a really nice way.

Just got one of these, and I must say it has me thoroughly impressed. Best envelope ever for my needs.
I also have Stages and Quadrax, and the level of control this offers is night and day to the others (which is the reason I got it in the first place).
Took a few minutes to get my head around but once you get it you get it.
Thanks for such a great module. Highly recommended !

Re: Module which unexpectedly blew you away?

Klavis quadigy, 4 x envelopes. All of the clock dividing and extra features make this ALMOST a modular brain, with just a few simple triggers to get it going.
It's just so quick and easy to use and sits at the center of my setup.

This really is a great module, intuitive to use, loads of control over the envelopes and lots of useful feedback on what's going make it a joy to use.
Big thumbs up to Klavis.

The quadigy is very snappy, I dont think it would leave you wanting.

Just gotta say WOW... I finally got Quadigy in my case.
It’s kind of amazing that’s it’s basically everything it claims to be.

I find Quadigy so much more gratifying as a complex EG... even with its menus.
At least I can see exactly what is going on without a "lightshow translation".
