Daniel Miller, artist and producer

To the Facebook poll "What module you recently obtained ended up being far better than you expected?", Miller aswer is:
"Klavis Quadigy. I had high expectations and they were exceeded, especially the CVability (is that a word??) which takes it to another level."
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.
But that thing looks like the mother of all ADSR’s with the ability to loop as well.
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.
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.

The Quadigy is a complex envelope generator focused on live play. The goal is to allow the user setting up rich, interactive and dynamically evolving envelopes without the risk of breaking up a subtle and intricate patch once on stage. This is achieved by offering two main modes, one where full control is available and a Live mode where only the settings that are sensible using on stage are accessible.

Update notes
Be sure to use to read the latest manual when updating the Quadigy to the latest firmware.

V1.10 corrects several bugs and adds the following features:
  • LED dimming
  • Screensaver
  • Better rendering engine
  • Manual gate for easy editing check
  • Quad control enrichment with tempo and div/mult factor as needed
  • Several user interface tweaks
V1.12 improves the curves dynamic rendering
