Buchla Tiptop 264T | ART protocol hacking with XAOC Drezno

video upload by Cinematic Laboratory

"According to Gur from TTA this was unlikely to work, but 'unlikely' is not impossible. The ART protocol is something like analog encoded digital data used to be transferred over regular patch cables. It carries information that can be used to play quantized notes on an ART capable VCO like the 259t (and obviously the ART series from TTA). I tried using XAOC Drezno to convert the ART signal to bits, and then scramble a few before recoding it back to analog. This is just an experiment and it was a bit too much off-topic for episode 14. It would also make the video too long and nobody's watching the end of long videos anymore. It makes me wonder if this could also work on MIDI data, but that's for another day."

Leibniz Unleashed | XAOC Leibniz Binary Subsystem | Episode 04

video upload by Cinematic Laboratory

"It's been six months since episode 03 (The Road to Berlin). This is mainy because I make videos as I go and as I learn. The Leibniz system, by itself is not difficult to use, but in the audio domain it's impossible to bypass the 8-bit sound quality and harsh noise is inevitable. I needed to take many breaks to make this video and I had to get my knowledge from the manuals and the excellent works of Tom Churchil. I never fully realized you need to make loops for best results and I didn't know how important 'reclocking' is. I experimented with external VCO's before I realized Berlin and Poczdam offer their own Leibniz clocks to manipulate and 'reclock' the datastreams.

I had many 'I did not know' moments while making this video, and often I had to reshoot stuff that did not make any sense anymore. I wanted this episode to be a 'Leibniz Unleashed' experience, showing off some amazing patches that have a lot to offer and complement what's already out on YouTube.

I guess a logical followup for Episode 05 is to explore musical applications some more, especially in the audio domain. Leibniz is just great for CV and rhythms, but (at first glance) not so great in the audio domain (unless you fancy glitch, noise and other raw genres, it excels here).

I hope this video will help you get more production value from your Leibniz set, or help you decide if it's something of interest. Modular is too expensive to just do a leap of faith and figure it out later. It can take a year before it starts to make sense. But it's been a great year!

"In this video, Tom takes a look at the Leibniz Binary Subsystem from Xaoc Devices: a range of modules that create and share 8-bit digital representations of analogue audio and CV signals in a Eurorack modular synth. It includes an overview of all eight current modules in the range: Berlin, Drezno II, Erfurt, Gera, Jena, Lipsk, Poczdam and Rostock.

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 :)."

XAOC Leibniz Binary Subsystem | Episode 01 | Intro & Drezno II

video upload by Cinematic Laboratory

"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!"

"I'm just trying out things with ROSTOCK to get a feel for it. This is a patch where I used it to create a phase-shifting or pitch modulation effect (depending on the speed of the modulation). By mixing in the original sound you can get phase cancellation in mono (comb-filtering?) or chorus in stereo."

Xaoc Devices Rostock & Drezno II: new patch ideas for the Leibniz Binary Subsystem

video upload by Tom Churchill

"In this video, I’m taking another look at the Leibniz Binary Subsystem from Xaoc Devices. This is a set of Eurorack modules that let you convert analogue audio and CV into 8-bit digital signals and then process them in all sorts of unique and interesting ways. Using various combinations of Leibniz modules, you can do everything from waveshaping and bitcrushing to sequencing and drum pattern generation.

Xaoc Devices recently sent over the latest modules in the system for me to check out. Drezno II is a new and improved version of their original analogue to digital and digital to analogue converter module which acts as the main front-end for the system. And Rostock is a binary data pipeline, or digital shift register, which lets you delay, loop, scramble and reclock the 8-bit data stream. In the video, I build a few patches that explore some of the musical applications of these tools."

Xaoc Devices ERFURT / not just for counting and dividing / extensive playthrough

video upload by BRiES

"In this video I demonstrate how you can use ERFURT either standalone or in the context of the Leibniz Binary Subsystem. I talk about the clock, the inputs and outputs and show you how to extract useful signals from the module. ERFURT isn't just an ordinary counter or clock divider: it can drive the wavetables in JENA, produce sequences through DREZNO or lock the Leibniz system to the masterclock of your patch... to name just a few examples.

PS: I mention somewhere that the slowest clock is a 1/46k but it should be 1/64k. It's a simple mispronunciation because of how numbers work in the dutch language (we say the last number first - ridiculous I know).

Xaoc Devices Sofia, Koszalin, Gera & Poczdam

video upload by Xaoc Devices

"Sofia is an unusual analog oscillator based on an original waveforming principle. The sound is a mixture of a warm saturated base tone and two modulating ripple elements. A wide array of control inputs coupled with separate outputs for numerous components of the sound shaping chain allows for extensive self-patching and complex animation of the final waveform. The resulting range of possible sounds is surprisingly vast, including but not limited to: vowel-like, tearing hard-sync effect, woody pings, warm and fuzzy sine-like evolving tones with a touch of bright sparkle on top. Sofia pairs very well with filters, but it also shines with just a VCA.

Xaoc Devices Koszalin

video upload by Xaoc Devices

"Koszalin is a full stereo frequency shifter (2 ins / 4 outs) offering both quasi-exponential and linear frequency change of up to +/-5kHz as well as full stereo feedback under voltage control. Frequency shifting results in linear translation of signal spectrum producing all kinds of atonal sounds. It should not be confused with frequency scaling, also known as pitch shifting. Complex phase cancellation patterns occurring with frequency shifting and deep feedback produce spectacular barber-pole effects. Koszalin offers direct control of feedback amount, feedback routing, and feedback response. It also facilitates frequency modulation of any stereo audio signal, thanks to the linear TZFM input.

"Gera

Gera is a component of the Leibniz subsystem that allows masking individual bits of the digital data by the use of logical AND operation. It features 8 individual gate inputs that affect the individual bits of data, as well as 8 illuminated tact switches for manual inverting of each control input. When connected to Drezno that is processing a waveform or voltage, masking of individual bits yields various forms of quantization.

Bit processing logic in Gera is hardware based, hence there is virtually no latency, and the binary signals may change at extreme rates.

Poczdam

Poczdam is a binary data routing solution for the Xaoc Leibniz subsystem. It allows manual and remote switching between two Leibniz data sources, modifying individual bits of the data stream, and re-clocking the data with its onboard voltage controlled wideband oscillator, or with any external clock signal. Poczdam is particularly useful with complex Leibniz setups that need to reconfigure the data flow between multiple modules. However, it can also be employed in small creative patches, e.g. for waveform splicing, disrupting rhythmic loops or generating digital chaos.

Xaoc Drezno and Jena quick patches

Published on Sep 2, 2019 Xaoc Devices

"Here is another quick video. This time I'm focusing on the new expander for Drezno module - Jena. Most of the time it is used as a wavetable oscillator/waveshaper - exploring also phase modulation possibilities. Next, you'll notice a short part where Jena's bit outputs are triggering Percs from our fellow company Polyend. This is possible because there is a special bank of wave shapes designed for percussive duties."

"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."

"We put together a whole system of XAOC Devices modules including the new Zadar quad envelope generator, two Belgrad filters that can be used as interesting oscillators when self oscillating, and a Kamieniec phase shifter. We also used a Batumi, Drezno and Tirana II for sequencing and modulation. The SSF Entity Percussion Synthesizer provides some drums.

The new Zadar is a powerful digital quad envelope generator with many different envelope shapes that can be warped and modulated. The Zadar can even run at high enough frequencies to be used as a kind of odd wavetable oscillator.

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.
