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
