The XAOC Devices Zadar is a powerful, four-channel envelope, modulation, and transient generator, in a compact yet very complete, feature-rich package. It is capable of synthesizing a vast palette of envelope shapes starting from hundreds of shapes stored in the memory. These starting shapes are not mere wavetables, but flexible vectors that can be stretched (from a fraction of a millisecond to half an hour), flipped, warped, distorted, delayed, shuffled, repeated, and amplitude modulated in real time.

A set of freely assignable CV inputs allows for external control of most parameters. Each channel can work independently or combined with other channels within one of the chaining and looping algorithms. Operating Zadar is quick and immediate, thanks to its accessible interface and crisp OLED display. The main screen displays all parameters together with the currently selected shape. Entering the simple 3-page menu is needed only for advanced settings. For detailed description, please refer to the manual.


  • Four independent channels
  • More than 200 unique shapes
  • Cycle time range: 0,08ms to 20 minutes
  • Shapes can be radically modified in two dimensions
  • Complex envelope looping and chaining features
  • Assignable CV inputs to control almost every parameter
  • Preset slots

Based on the general idea of synthesis by deformable vector shapes, Zadar allows you to choose from a wide variety of envelope functions, designed to suit pretty much any possible usage scenario. From basic and simple to complex transients, from looped modulation cycles to rhythmical patterns, from quasi-randoms to perfectly regular functions, natural envelopes extracted from various acoustic and electronic instruments, abstract fractals and physical models, etc. — they all work great as envelopes but also as stepped sequences, LFOs, resonator exciters and so on.

Starting with one of (literally) hundreds of shapes defined by freely scalable vectors of breakpoints stored in the memory, envelopes can be tweaked and adjusted to the heart’s content. Each shape consists of up to a thousand of segments, and it may be warped in time and amplitude, reversed, stretched from a fraction of milisecond to about 20 minutes, and of course attenuated. By manipulating these parameters you can easily obtain a plethora of new shapes, but it doesn’t end here. Envelopes can be repeated, looped, chained and each channel sports a freely assignable CV input, allowing for most of the above mentioned transformations to be externally controlled as well.

Operating Zadar is quick and straightforward thanks to the set of four “endless” encoders. Menu diving has been reduced to minimum, and is actually only needed for the advanced settings. A crisp OLED screen provides the necessary visual feedback in real time. All the settings can be stored and organised in preset slots.

The Zadar envelopes can even be looped and run at audio rates, in order to be used as experimental oscillators. Please note that they do not accurately track 1v/oct, although setting the TIME CV sensitivity to +50 will approximate this response.

There are plans for even more functions to be added in later firmware revisions. Also, a small but very useful Nin expander module is planned, sporting yet another set of individual, assignable CV inputs and manual trigs for each channel for better tweaking comfort.
