Xaoc Devices Lublin

video upload by Xaoc Devices

"Lublin [ˈlublin] is a dual, DC-coupled, high-quality VCA module with exponential control characteristics. It features a gain control circuit that prevents distortion from excessive amplification, which is common with traditional VCAs.

Besides audio and CV inputs, it features additional pinging inputs that use an elaborate analog circuit to model the dynamic behavior of vactrols, allowing you to trigger a carefully crafted gain response that mimics the natural decay of plucked and struck acoustic instruments.

Note that despite this emulation, Lublin is not a lowpass gate type module as it retains the full frequency bandwidth when reducing gain. Unlike many modules that use vactrols, Lublin's dynamic profile can be varied within a wide range.

Dual Voltage-Controlled Amplifier ∙ High quality, low noise and distortion, DC-coupled signal path ∙ Ping inputs for emulating vactrol response ∙ Three variants of ping response ∙ Exponential CV response with adjustable sensitivity ∙ Gain limiting circuit for protection against signal clipping

Xaoc Devices Lublin: pinging for the new era, or strike your VCA!

They say you can never have too many VCAs. So we decided to make another one, actually two in one. After our modern classic that is Tallin, lauded for its inimitable saturation circuit, it's time for Lublin [ˈlublin]! Lublin is a high-quality dual VCA module with exponential CV inputs. On top of that, its two identical channels feature additional inputs for pinging. These inputs use an elaborate analog circuit to model the dynamic behavior of vactrols, allowing you to trigger a carefully crafted gain response that mimics the natural decay of plucked and struck acoustic instruments. Unlike lowpass gate modules though, Lublin reduces gain while retaining the full frequency bandwidth, so it is perfect for harmonically rich signals, like our Odessa additive VCO. The vactrol-like behavior is just a starting point as the envelope may be varied within a wide range using a switch (natural, shortened and prolonged response) and a potentiometer, so you are not stuck with one decay characteristic. Therefore, you can use it not only to create bongos, but also for fat compressed kicks! The built-in gain control circuit (saturating CV instead of the audio signal) prevents distortion from excessive amplification. Lublin is DC-coupled, so you can use it to process CV as well as audio signals.

Notable features:
- Dual Voltage-Controlled Amplifier
- High quality, low noise and distortion, DC-coupled signal path
- Ping inputs for emulating vactrol response
- Three variants of ping response
- Exponential CV response with adjustable sensitivity
- Gain limiting circuit for protection against signal clipping

Hacking the XAOC Berlin VCO

video upload by ALEQ Modular

"The XAOC Berlin is a digital VCO compatible with the Leibnitz system of XAOC. This system allows to play with bits: Interesting !

Here, I'm using the Leibnitz connectors, and two multiple from Larix-Elektro to have access to the 8 bits that generate the SAW wave.
Just because it's very simple way to convert the Leibnitz connectors into jacks !

And after, I'm explaining how to produce new kind of waveforms.

This is not a safe way to use the module. But its a good way to understand it, and thinking about acquiring some Leibnitz compatible modules, to play with bits !

Note:
The Multiple from LE is not yet available, this is a prototype originally designed to add I/O to others modules like the 4TOMS.
Shold be available after this summer.
Thanks to the LE CV Generator, and the Attenuverter Bank, from LE too...

PS:
Try this carfully: I haven't checked how the circuit is built, if the I/O of the Leibnitz connector are protected. So maybe you can damage your module...
I strongly recommande to use modules from the Leibnitz system instead."

Stereofication | feat. Makenoise 'Bruxa', QPAS SmilePass and XAOC Minsk

video upload by Cinematic Laboratory

"After the release of Bruxa two days ago, I noticed a lot of comments about it being a mono delay in a world that quickly goes stereo. So in this video, I'll use the concept of a mono delay and check out two options to stereofy it (besides running it through a stereo delay, granulator or reverb). QPAS smilepass is an 'allpass' filter which can produce 'false' stereo effects. XAOC Minsk really perfected this 'art' and can turn Strega/Bruxa into a wonderful stereo swirl with absolutely no effort. Higly recommended."

Making Music With The Leibniz Subsystem

"The Xaoc Devices Leibniz Subsystem is a gateway to all kinds of experiments in the Eurorack ecosystem, but it can also serve as a foundation for more traditional music compositions. See how you can achieve this with a few simple patches that you can incorporate into your own system."

The Road to Berlin | XAOC Leibniz Binary Subsystem | Episode 03

video upload by Cinematic Laboratory

"I got a bit stuck after doing the 2nd episode. Yeah, that episode sucked, but that also happens at the Lab. Dead ends are important if you want to learn to think more in u-turns. In this episode, we're back on track.

I knew the Leibniz Binary system would give me a hard time, but I underestimated that. I had a few weeks staring at my case wondering 'what's next?'. Sure, there's plenty to explore, but it's hard when you don't resonate well with the broken chiptune sounds - which are inevitable. Then, XAOC added 'Berlin' to the list of cities. It's labeled a 'numeric' VCO and it's designed especially for the Leibniz modules. It's basically a simple sawtooth with 1V/OCT, FM and Sync, but it's more like a quality D/A converter for generating waveforms. The Drezno II used to take care of that, but it would make jagged waveforms by summing lots of squares. It sounds very 8-bit. Berlin doesn't have that problem, it sounds great.

In this episode I am not doing a deepdive yet, because I just got the module. Instead I'll try to explain why it's relevant, and how a sawtooth gets all these odd/even harmonics and overtones. Why it's considered 'rich' compared to a sinewave. Then, it's easier to understand why Berlin only has a sawtooth (or scrambled saw) out. When you draw a graph of numbers 0 to 255, you'll get a nice ramp (reversed saw) that flips back to zero and counts up again. Berlin is basically counting up very fast and restarts at 0.

I'll leave the interaction between Berlin and other modules to episode 04, which will probably be posted next week. It's not going to take too long :)."

u-he CVilization Mode I: Musical demo (no talking)

video upload by u-he

"Here's a jam featuring our CVilization module in Mode I (4 x 4 Matrix Mixer). We're exploring the musical possibilities of the mysterious Matrix Rotation [posted here]. 4 different oscillator signals are routed through CVilization's matrix and distributed to various other modules. CVilization now rotates its inputs and outputs, creating ever-changing mixes of these oscillator signals. CVilization's sidekick Wiretap also joins the game with two of its outputs hooked up, creating some funky alternating envelopes.

XAOC Koszalin | Using the Frequency Shiftor on vocals

video upload by Cinematic Laboratory

"Sorry for the distracting dialog, which kind of illustrates that I don't like to speak on my videos.
But this time, I had to use a voice to demo frequency shifting on vocals. I couldn't avoid it.
I could have used a professional voice-over artists, but that would make my free videos unsustainable. Regardless, Koszalin is an awesome module that can completely transform any sound you throw at it."

SUPERBOOTH 2024: Xaoc Devices - Berlin Wide Range Oscillator

video upload by sonicstate

"At Superbooth 2024 we met up with Lukasz from Xaoc Devices who unveiled their new* Berlin* module.* Berlin* is an extemely wide range VCO module ranging from 30 seconds up to 250 kHz. That range is wide! It uses the Leibniz Binary Subsystem interface and can be used as an extremely widerange clock source allowing for manual and voltage control over all parameters. Berlin outputs simultaneous square and saw/Leibniz wave outputs and when combined with the Liebniz Subsystem allows for extensive waveshaping.

Berlin Price: 220 Euros"

Xaoc Devices Berlin: the oscillator that opens up the Leibniz Binary Subsystem

video upload by Tom Churchill

"On the surface, Xaoc Devices Berlin is a simple compact VCO offering square and saw waves with hard sync, FM input and octave switching. The most interesting part lies behind the panel and that is the Leibniz Binary Subsystem interface, namely LBZ out and LBZ in. The frontpanel LBZ LINK button and its corresponding gate input switch between the default saw wave and a signal that has been passed through any Leibniz module (or a combination of Leibniz modules) connected to Berlin. Add Xaoc Devices Jena for wave processing and the output is no longer a simple saw wave – you now have a vintage-style wavetable oscillator with a penchant for the experimental due to its open, hackable nature. Berlin operates in a way similar to the classic PPG Wave and Fairlight CMI synths and employs a variable sample rate of an extremely widerange internal clock. As the sample rate changes with the oscillator frequency, Berlin's internal square and saw waves exhibit no aliasing effect. The whole frequency range spans from 30 seconds in LFO mode up to 250 kHz (!) with the clock reaching an astounding 20 MHz. Add to that voltage control over all parameters and the result is a highly versatile module capable of creating a significantly diverse palette of unusual waveforms.

Xaoc Devices Berlin notable features:

– wide-range VCO with LFO mode (over 20 octaves of tracking);
– Leibniz Binary Subsystem interface;
– extremely widerange clock source;
– manual and voltage control over all parameters (including octave switching and LBZ LINK!);
– simultaneous Square and Saw/Leibniz wave outputs;
– extensive waveshaping potential when combined with Xaoc Devices Leibniz Subsystem modules, e.g., Jena or Rostock"

XAOC Sopot | Magic Duct Tape for your audio puzzles (w. MakeNoise RxMx, Plaits & Frames)

video upload by Cinematic Laboratory

"I got Sopot a few weeks ago, but got focused on the Leibniz modules and forgot about it a bit. It almost never made it to a case because space is limited and I had to make choices. Yesterday I checked out the manual, tried some patches and a wealth of new ideas just popped up. This is a simple 6HP utility, costing around 90 euro, but it can solve a fortune of mixing challenges when a big fancy mixer is not an option.

In short, Sopot is a summing mixer with four stereo inputs (!) four mono inputs (!!) and mid/side outputs, or mono/stereo if you wish. The mono inputs are normalled to the center, but can be panned 50%/50% with a little center spread. This design is amazing. Highly recommended."

XAOC Leibniz Binary Subsystem

video upload by Cinematic Laboratory

"In episode 1 [posted here], it was fun to dive in. Then I found out that the system isn't just a matter of putting all modules in a case, wiring up the I/O on the back and get to work. It's modular (duh) so it's more a matter of recipes where the order of modules isn't fixed. Having all modules in a case doesn't exactly help to understand them either, there's just too many variables and it's extremely easy to make a wrong connection with the 'pale pink stripe' down or up on the LBZ ribbon cables. You really need to double check and then again. XAOC, make them red. Please.

In this episode I tried to get the Rostock module to work. It's a bucket brigade 'delay' with 64 memory locations. Or a shift register. Anyway, it allows you to accumulate values from the bus and store them so you can loop it. However, with a clock running at 2 mHz you don't hear 64 bytes when millions come by. If it's even audible it's in the nanosecond range. I had to slow down to actually see the module work.

XAOC has provided cool patch examples in the manual and I focused on delaying/looping rhythms with Rostock, Lipsk (bit inverter) and Poczdam (router/binary output). I am also using Odessa in the video, which is a truly amazing VCO which also has a Leibniz header on the back to control partials with bitmaps. I absolutely LOVE this system and can't wait to get started on episode 03."

"My first ignorant impression was 'it's a fancy bitcrusher' which may be 10% right. It's about musical applications with binary logic. Thanks to Bries and Tom Churchil for their masterclasses so I may be able to figure out the other 90%.

As always, I am not sponsored by XAOC. I wish, but it's too late now. I have Lipsk in backorder and that will probably conclude my case.

Dear XAOC if you feel thankful while this series progresses, I still have a short wishlist like Odessa, Batumi, Samara, Belgrad and a mixer. But I am already happy you made these modules!"
