Xaoc Devices Minsk & Zagrzeb Eurorack Modules

Press release:

Xaoc Devices Zagrzeb & Mińsk – two faces of stereo processing

Are you ready for some stereo action? Xaoc Devices continues exploring the stereo processing realm with two new modules unveiled at this year’s Superbooth.

Zagrzeb is a stereo multimode 4-pole (24dB/oct) state variable voltage-controlled filter (SV VCF). It offers five distinct frequency responses, three of which are available simultaneously. Spread control allows for animation of the stereo image by moving the left and right filter cutoff frequencies in opposite directions. Zagrzeb is designed to sound smooth and clean unless it is overdriven with a hot signal— however, it does not lack character! We believe it will be appreciated by fans of old Japanese synthesizers, but bear in mind that Zagrzeb is not a clone of any existing design. The four-pole state variable structure is a new development and offers unique sonic characteristics. While Zagrzeb is designed for filtering stereo signals (e.g. samples or stereo oscillators like Xaoc Devices Odessa), it can easily handle mono signals and is capable of creating a faux stereo pair thanks to a special phase shifting network at the input.

– Stereo, four-pole state variable filter
– Five frequency responses, three available simultaneously
– 24dB/oct low pass and 24dB/oct high pass filtering
– 3 band pass filter slope configurations
– Voltage controlled Spread control for animating the stereo image
– No LF drop at high resonance
– Mono to stereo image effect
– 8hp, skiff friendly
– Current draw: +70mA/–60mA
– Reverse power protection




Mińsk is a stereo image processor. It is a hybrid tool that combines digital and analog processing to facilitate advanced mid/side (M/S) manipulation of a stereo signal pair. It allows for separate treatment of the mid and side components, which affects the depth and width of the auditory scene. Mińsk offers both manual and voltage control of the stereo width, as well as two dimension effects for enhancing the existing stereo image or creating a faux stereo image based on the stereo or mono input source. Mińsk is especially handy during the preparation of a vinyl release or before a club concert, because it can eliminate out-of-phase low-end frequencies (high pass filter at 300Hz with the filter slope 12dB/oct, 50Hz with the filter slope 24dB/oct).

– Stereo image manipulation tool
– Mid/Side processing
– Mono to faux stereo conversion
– Stereo dimension enhancement
– Manual and CV stereo width control
– Low cut on side component
– Visual stereo image indicator
– 6hp, skiff friendly
– Current draw: +140mA/–40mA
– Reverse power protection

Zagrzeb: 260 EUR MSRP, available in October 2021
Mińsk: 190 EUR MSRP, available in October 2021

How to create pre-filter stereo patches on the modular – Zagrzeb - Xaoc devices

video upload by Monotrail Tech Talk

"Zagrzeb from Xaoc devices is a great, compact and smooth stereo filter. That makes it perfect to deal with complex stereo signals. But how to make these? In this video I go over the functions and features of Zagrzeb, but also share lot’s of ideas for pre-filter stereo patches. Both with basic synth-ingredients, as well as a couple of dedicated stereo modules.

Xaoc Devices Zagrzeb: A Musical Video Walkthrough

"A text-on-screen walkthrough of the XAOC Zagrbzeb stereo multimode filter which sounds really good I think, honestly. Patch notes are shown on screen during the video."

Setonix Synth and Bastl Dual Filters

video upload by John Schussler

"I've already looked at the Setonix Synth Marsupial. Really liked it, and was accordingly quick to order the Macropod when it became available. At about the same time I got ahold of an Ikarie from Bastl.

Between the three of them, I have a hard time choosing a favorite, and all are definitely keepers.

This is a short comparison to get a feel for their respective sounds. I'm not spending a lot of time on the Marsupial since I already covered it (see link in description/above), but do want it here so I can have a clear ear on how it differs from Macropod.

Source VCO is a Dannysound Cali Osc. Envelope from Zadar. Sequence from Stochastic IG. And a touch of Valhalla reverb at the end.

8hp Eurorack Filters

video upload by

"So you have 8hp available, and want to fill it with a filter. Here are some options. They aren't all the options, there are many, many more. But a few new 8hp filters have arrived recently (the XAOC, CCTV, and SetonixSynth), so it seemed like a good time to compare them with some other 8hp filters I have close at hand. For the most part I'll be listening to low pass outputs only.

Source audio is an Intellijel Dixie II+, with a mix of several waves. Envelope is from Zadar. Sequence from Stochastic SIG. A touch of Halls of Vallhalla reverb at the end.

POLARITY - MODULAR SYNTHESIZER LIVE PATCH EXPLAINED

video upload by A Last Picture From Voyager

"Recently I received a clone of the 'rings' from mutable instruments to replace my 'telharmonics', and an 'MFX' multi effect from ALM. After a few test patches I dove into a melody that swept me away. And from a melody, I made a complete piece to which I just had to add a bass line to bring depth. As always, I tried to explain this patch with some subtitles. The way I use the filter for this patch is well explained (with other techniques) inside a XAOC Zagrzeb dedicated video from @MonotrailTechTalk Don’t hesitate to ask for more in the comments."

First 10:
1. Fireflies | Modular Eurorack Beat | Erica Synths LXR, Basimilus Iteritas Alter #Jamuary2023 01

First Video this Year! I started this Patch trying to use my new Erica Synths LXR Eurorack Module for a melodic voice which I think turned out pretty nice. Bloom and Pamelas New Workout are responsible for the sequencing. Main Melody 1: LXR receiving v/oct from Bloom, sent through Mimeophon. Main Melody 2: 2hp Pluck sequenced by Bloom, mixed with Noise and filtered by Forbidden Planet through Disting Delay. Bass is Plaits, distorted and filtered by Peradam and XAOC Zagrzeb. Kick: Basimilus Iteritas Alter Drums: Erica Synths LXR

2. Karmesin | Modular Eurorack Beat || #jamuary2023 02 ||| Queen of Pentacles, Acid Rain Chainsaw

Drums: Queen of Pentacles & some additional Hi-hats made with white and pink noise Main Melody: Acid Rain Chainsaw Bass: Basimilus Iteritas Alter Background Texture is Plaits with the model Input modulated.

3. SHORES | UK GARAGE on MODULAR || #jamuary2023 03

I've been wanting to make some kind of UK garage, burial inspired piece on the modular. I think it turned out pretty neat!

4. EMBERS | Drum and Bass on MODULAR || #jamuary2023 04

Here we go again, 4th day of #jamuary2023! I try to keep it as musically diverse as possible, so I tried to make some Drum and Bass this time. I think it's quite alright for the first try!

5. Below 0 | #jamuary2023 05 || Eurorack ||| Patch Notes on Screen

It's been a long time since I wanted to use the Forbidden Planet as an Oscillator and I never found the place in a patch since it is always almost on regular filter duties. But I managed this time and it sounds very cool!

6. Erica Synths LXR Eurorack Live Techno Jam | #jamuary2023 07

#jamuary2023 lets go! Part 6! I filmed this video when I just got the Erica Synths LXR, wanting to showcase some of its sounds! I think it sounds absolutely massive!

7. Leaving | Eurorack Drum and Bass || #jamuary2023 07

More Drum and Bass! I'm really happy with the drums in this. I stumbled across the melody by accident just fiddling with Bloom.

8. Happy Accidents | Chill Eurorack Beat | #jamuary2023 08 | Patch Notes

This was a happy accident by slowing down one of my other #jamuary patches. I then changed the drums and the main melody so it fit the tempo better.
