Xaoc Jena, Drezno, Lipsk: Leibniz Binary Subsystem update!

Post by mantiwhore » Sun Apr 16, 2017 2:49 pm

Xaoc Devices presents:

Jena
1989 Binary Transfunctioner


ModularGrid: https://www.modulargrid.net/e/xaoc-devices-jena
User manual: http://xaocdevices.com/manuals/xaoc_jena_manual.pdf

Image

Yes, finally. The new component of the Leibniz Subsystem which operates on signals and voltages through manipulating binary 8-bit numbers. Jena connects to the Drezno module in a loopback. A binary transfunctioner maps input functions (eg. waveshapes) to some other functions through the classic table look-up mechanism. Input 8-bit values are treated as indices to an internal memory map. The value read from successive locations of the memory are passed to the output.

A simple VCO sawtooth or a triangle wave may be transformed to a plethora of waveshapes from any of the shape banks, with additional, deep through–zero phase modulation. Individual bit outputs may be used to produce interesting signals as well. There is a dedicated bank of Walsh functions — with these signals you can perform additive Walsh synthesis, not very common in Eurorack, but a quite powerful technique.

Transforming slow waveforms to sequences of binary signals is a great way to create rhythmic drum patterns. Jena comes with a special bank that has plenty of such patterns — just connect up to 8 drum voices to individual bit outputs on Jena. The rhythms can be selected or morphed on the fly through external CV input.

Obviously, being limited to 8 bits both in phase and signal value, Jena will not deliver crystal clear timbres you may know from many wavetable oscillators. Instead, it offers buzzy, jittery and gritty sounds as well as jerky and skippy rhytms, just like vintage computers, that were sometimes unreliable and unpredictable.

• Digital waveshaper and function mapper
• Through–zero phase modulation
• Walsh function generator
• Drum pattern generator
• Voltage controlled bank and shape scanning.

250 EUR MSRP
Shipping later this year.

Come visit us at booth E220 on Superbooth 2019 to play the Leibniz Binary Subsystem.



Already available:

Drezno
1989 Binary Conversion Komputor

12 hp, 260 EUR MSRP
Manual: http://xaocdevices.com/manuals/xaoc_dre ... manual.pdf
ModularGrid: https://www.modulargrid.net/e/xaoc-devices-drezno

Drezno consists of a flexible ADC (analog-to-digital converter) and DAC (digital-to-analog converter)
that can be cross-patched, or used independently. It offers:

• digital manipulation of analog signals and voltages
• converting slowly changing voltages to 8 rhytmic gates
• converting combinations of up to 8 gate signals to complex waveforms
• quantization and bit mangling or crushing of signals
• a digital sample&hold function

The input is converted to digital representation and made available in the form of 8 binary (gate) signals.
These signals can be freely mixed, scrambled, inverted, cross-patched, etc. At the end, 8 binary signals are
converted back to analog domain. Both conversions may be performed synchronously with external clock
patched to respective clock inputs, or asynchronously, at high speed of internal clock. Drezno can handle
signal changes as fast as 1MHz, so there is no aliasing with audio rate input.

Drezno may also act as an input/output device for an upcoming barebone "Leibniz" digital signal processing
subsystem.

Lipsk
1989 Bit Inversion Commander

6 hp, 150 EUR MSRP
Manual: http://xaocdevices.com/manuals/xaoc_dre ... manual.pdf
ModularGrid: https://www.modulargrid.net/e/xaoc-devices-lipsk

Lipsk is an expander for Xaoc Drezno module that allows to flip (invert) individual bits of the digital signal
representation. It features 8 illuminated tact switches for manual control as well as 8 individual gate inputs.
When connected to Drezno which is processing a waveform, inversion of individual bits yields fractal-like pattern
waveforms.

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

Fuck!

I love messing around with these modules in the Nord G2. To have it in hardware would be amazing.

There are a couple of modules with similar functionality available, some of which are really great to play with. Still, nothing that offers both in one package and nothing as sleek and sexy looking as what Xaoc offers.

Super nice! Looking forward to seeing it in the flesh at SuperBooth!

:woah:

How refreshing and very intriguing, can't quite imagine how these are going to behave/sound, but going to find out for sure!!

Ha this is great! Well done guys. This should be a lot of fun for bit-crushing audio, LFO mangling, or even as a 2^n equal temperament quantizer (does it work?).

So if I understand correctly a fast clock is normalized to the clock inputs? how fast?

Yes, the internal clock is normalized to the ADC CLOCK input, and the actual ADC clock (as selected in the socket) is normalized (through a chain of expander headers on the back) to the DAC CLOCK socket. The internal clock is about 2MHz, so it will handle full audio bandwidth signals without aliasing (and it sounds pretty good for an 8-bit representation).

Quantization to equal temperament is possible, but may be tricky to set up with free controls over scale and offset on both sides. Also, the converters are 8-bit, so the accuracy may be a insuficient for accurate tuning (the conversion error is usually worse than just the theoretic quantization error)

Converting a signal or CV to digital representation opens a whole dimension of digital transformations that may be performed on them. Flipping and cross-patching bits (as offered by Lipsk) are just the simplest operations that affect the instantaneous value of the signal, so they can be called memoryless. The Leibniz subsystem is a planned suite of expanders that will operate digitally in time and frequency domain by using some computing techniques from '70s and '80s.

Fantastic stuff! Great ideas, and from the Xaoc-modules I know such as the Batumi or even my Warna, great execution. Decent aesthetic design-choices as well- I'll be following you guys closely-

Ah, Leibniz as in:

∫ and dy/dx

Will this be a calculus machine?

Well ... not exactly, this guessing went too far 8-)

Integration and differentiation is (almost) perfectly handled by analog circuits, no need to employ digital for that. Instead, we will explore the various aspects of 8-bit arithmetics in this barebone subsystem.

As for hints, consider that besides inventing the differential and integral calculus, Leibniz also significantly contributed to the development of mechanical calculators. He was born in Lepzig (Polish name: Lipsk). And Dresden (Polish name: Drezno) was the location of VEB Kombinat Robotron, the biggest East German manufacturer of personal, mini-, and mainframe computers.

Ah man, I love this kind of stuff. I guess I am going into Eurorack after all. Perhaps I can get something to shrink my hands....

So, are we talking wavetables and 8-bit DSP?

Yes, but I can't reveal the details atm. It's still in development.

Beautiful work as always, Xaoc crew.

I don't fully understand what this does at first glance, and that's a good thing.

Awesome to see such a fresh idea in a new module :tu:

Can't wait for someone smarter than me to help me understand it! :party:
