Klevgrand releases free public alpha of KRETS – build your own VST plugins. Experimentation encouraged and feedback welcomed!

KRETS is a modular environment that can be used in any DAW compatible with the AudioUnit or VST format.

The application is based on a set of modules that can be connected in different ways, where focus is on low level audio DSP processing. There are (almost) no ready-made effects to hook into an audio stream, the purpose is for the user to create these more or less from scratch.

By combining mathematical expressions and functions (available as modules) a plethora of audio effects can be created, anything from a compression algorithm to generative soundscapes.

Although in an early development phase, Klevgrand would love if you would like to play with it. Maybe you’ll find a couple of bugs, maybe you’ll invent a killer distortion algorithm by accident. (true story: An accidental algorithm is actually the reason that Klevgrand started making plugins in the first place)

In order to use KRETSyou’ll need a Klevgrand account. It is very free and lightweight. You’ll also need a Internet connected computer to run it.

Note that KRETS is currently in a Public Alpha version, meaning two things:

  1. A lot of things may change, including functions, graphics & other features.
  2. Anything created with Krets may be lost or broken in upcoming releases.

Knowing and understanding this, you’re invited to try it out yourself!


When working with signal generators and complex signal paths, there is always risk for unintentional high level audio signals. It may very well damage your hearing if things go wrong. Make sure to turn down the volume if you’re unsure about what an interaction may result in.
