Xaoc Odessa - a bit more experimental approach

Published on Aug 24, 2019 Xaoc Devices

"Here are two more quick patches with Odessa oscillator, one exploring more rhythmic side of our new module and another with a bit more experimental approach. During rhythmic part three outputs are used with independent VCAs and AD envelopes as three drum voices. Sequence is generated with our forthcoming Drezno expander - Jena. Second patch is based on feedback - through zero FM input is fed with fundamental output, only external modulation is slow sine changing density parameter."

Odessa quick jam

"This is simple patch with final revision of Xaoc Devices Odessa. All three outputs of Odessa goes to three Xaoc Tallin VCAs in clean mode. VCAs are fed by simple AD envelope from Xaoc Zadar and mixed with Xaoc Praga. There is no additional filtering only some reverb. I've added drums in background just to make it more enjoyable to listen!"

4 new Eurorack modules from XAOC Devices // Superbooth 2019

Published on May 29, 2019 DivKidVideo

"XAOC Devices brought 4 new modules (5 if you count the expander or updates) to Superbooth with a BBD delay, DSP FX platform, utility module updates, analogue computing AD/DA 8 bit wavetable action and plenty more. We have Jena, Sarajewo, Timiszoara, Samara II and NIN. It was nice to hear Odessa is going to into production soon which I was really excited about last year."

"Xaoc Devices always have a lot to show of at the shows and this year is no different! They had Sarajewo a Syncable Analog Delay Line, Jena Binary Transfunctioner, Timiszoara Voltage Controlled DSP Effektor and Samare II utilities and a quick update on the Odessa Harmonic Oscillator.

Analog syncable delay line is something very special indeed, so we were keen to check this out and everything else from XAOC."

XAOC Devices - Workshop at SchneidersLaden

Published on Feb 4, 2019 SchneidersLaden

"Maciek, Marcin and Tomek from Xaoc Devices were so kind to explain their more sophisticated modules to us. What initially looks like a lecture at university, is actually a quick and very good explanation of the huge and often overlooked possibilities of their Drezno and Lipsk modules. Those two go to the heart of digital-to-analog conversion (and the other way round) and are therefore perfect examples of what makes modular synthesizers interesting in the first place! You can go as deep into the shaping of sounds and modulations as possible! At the end of the workshop they also talked about their first VCO module - Odessa, an additive oscillator with great potential.

Here is a little time-table for you - so you can jump to the bits that you want to see:

Superbooth 2018 - XAOC Devices Odessa Additive Mega Oscillator & Zadar Quad Wavetable Envelopes

Published on May 11, 2018 DivKidVideo

"There's a lot of talk about the new Odessa from XAOC Devices. It's a 512 partial additive oscillator. With fundamental, odd and even outputs, multiple voices for unison FX, through zero linear FM, lots of harmonic control - it's a totally new thing for the format. There's Zadar which is a quad wavetable addressing envelope for complex shapes and manipulation. This can also go up into audio rates which I'm sure is interesting too.

1975 Variable Spectrum Harmonic Cluster Oscillator

· Additive synthesis engine
· 2500 harmonic partials generated
· Straightforward user interface
· Through-zero linear frequency modulation
· Detuneable clusters of up to 5 voices

Odessa implements the principle of additive synthesis controlled by a set of carefully tailored marco parameters to harness thousands of sinusoidal partials that altogether form the resulting sound.

The interface is kept simple and accessible, so you can easily build rich and full, great sounding timbres of very complex spectra, that can be either harmonic or inharmonic. Even though inharmonic spectra yield non-periodic waveforms, all partials are frequency related to the common fundamental controlled by a V/oct input. The series of harmonics can be squeezed or spread apart, tilt, and pruned by a comb-like frequency response, resulting in a variety of unearthy sounds. Animating the comb response yields radical effects similar to flanging and phasing. Additional, often sought after features are implemented: through-zero linear frequency modulation, and unison detune: up to 5 copies of the sound can be spread apart for a fat and dense cluster of voices.

There are nine parameters, each controlled by a dedicated knob, so the workflow is as smooth and immediate as possible. Furthermore, every parameter has a dedicated CV input, allowing live animation for organic audio effects. Odessa sports two main outputs for banks of harmonic partials that can be further scaled in frequency, as well as an additional output that can either spit out a square wave or a a single sinusoid of the fundamental frequency. Interesting spatial effects, crazy modulation feedbacks as well as synchronisation is possible that way.

The hardware is based on a powerful FPGA chip offering massive parallel computing. The synthesized signal is devoid of aliasing through the entire audio range thanks to intrinsically bandlimited algorithm. A simplified spectral analyzer helps you to keep a visual track of what is actually happening to the harmonics.

For even more control over Odessa, you can use our Leibniz subsystem (or just the Lipsk) that can be connected to a header at the back of the module."

1973 Quadruple Envelope Generator

· Four indepenent channels
· More than 200 unique shapes
· Cycle time range: 0,08ms to 20 sec.
· Shapes can be radically modified in two dimensions
· Complex envelope looping and chaining features
· Assignable CV inputs to cotrol 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.

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."
