"Ilse the Eurorack synth voice in one DIY module is making warm but harsh Berlin Techno / Surgeon style stabs.

Ilse is an elegantly minimal, yet fully functional synthesizer voice in a compact 10 HP Eurorack module. The only thing you need to let it meow is a CV source to trigger its 1V/Oct frequency input (or a MIDI to CV converter and a MIDI sequencer) . Because it has a low part count it is ideal for Eurorack beginners or entry-level DIY projects.

Ilse is named after a cat, living in the legendary “Villa” in Weimar, Germany. The “Villa” was a place where a community lived and came together. Many underground concerts and parties took place here before the house got sold, renovated, and the mayor moved in. We created the graphics on the aluminum face-plate in her memory. Ilse (the synth) makes great acid sounds, so it was only logical to illustrate a cat tripping. Turn the knobs to make her look around or roll her eyes.

Ilse is designed to be affordable, easy to build, yet flexible, and feature rich. It is a synthesizer voice for your Eurorack, but can even be driven without a rack using two 9V batteries (not included).

Ilse is fully open source (KiCad schematic and layout is available in a git repository) and inspired by Syntherjack’s single-chip synthesizer Totoro. Check out his website with nice explanations, e.g. on the filter (we use the same filter on Ilse). We extended the design for external voltage control on filter, oscillators and LFO. Unlike Totoro, Ilse is designed around a unique oscillator design, which integrates the exponential conversion directly into the oscillator core. This results in an efficient circuitry saving you build time, parts and costs.

PCB and face-plate are manufactured in the EU. Kitting was done by our friends from Befaco in Barcelona. Complete assembly manual can be found in our forum.

CHAIR Analogue Waveguide Resonator - Gesprächskonzert SUPERBOOTH24

video upload by Superbooth Berlin

"In 1971, the congenial mathematician, quantum physicist and room acoustics expert Michael Gerzon published an article about a reverberation device. The device in question used a matrix operation to rotate two signals inside each other. He concludes in his article that it would be impossible to build the device using existing technology.

In this conversation concert, we present Gerzon's device, re-imagined as a resonator. Its complex analogue circuitry is based on two bucket-brigade delays and an analogue rotary operation. Thanks to this circuitry, our new Eurorack module produces rich harmonic and inharmonic spectra, creating physical and vivid sounds with astonishing depth and detail. For the first time, efficient physical modelling synthesis is possible in an analogue signal path, going beyond the usual harmonic string sounds and opening up fascinating new soundscapes. The Resonator offers a wealth of parameters, yet remains intuitively playable, inspiring audiences and performers alike."

The Center for Haptic Audio Interaction Research Introduces Analog Waveguide Eurorack Module

'The Center for Haptic Audio Interaction Research presents the Analog Waveguide, a Eurorack module for physical modelling synthesis."

"Analog Waveguide is versatile stereo reverberation effect that feeds the signals into a rotation matrix. The matrix can be set to any angle. Its signal path is fully analog, and the delay lines are implemented with bucket brigade delays. The design was described in a concept by Michael Gerzon from 1971, but was only implemented digitally in 2011 by Miller Puckette. Our interpretation re-implements and extends the original concept as an Eurorack module with an analog signal path. The resulting resonator is an analog waveguide for vivid physical modeling sound synthesis . The integrated display shows the two signals in a Cartesian coordinate system. The resulting image visualizes the complex oscillating signal in the resonator. The wide range of forms and movements is mesmerizing to watch and allows for a synaesthetic experience of the instrument. The visual representation of the signal also assists the experienced user to remember and recreate parameter settings for specific sounds."

SUPERBOOTH 2022 Analog Physical Modelling (on a bike)

"The man (Max) with the bike and the long micro phonic piano wire could sound like some kind of torture, but Dom swung by during one of our Superbooth Live Streams. Nick went back to find out more and discovered that he was actually demonstrating a prototype of their CHAIR (Centre for Haptic Audio Interaction Research) analog physical modelling . They already make a VST Plugin which uses excitation. But on display was an analog waveguide physical modeling module. Max explains int he video

No pricing or release dates yet, but his booth was a bike.

Stand alone and eurorack as seen below.

via SUPERBOOTH.COM:

"Our mission is to make sounds tangible. That's why we are developing instruments with haptic interfaces for electronic sound - both analog and software synthesis. Our Instruments have excitable surfaces that you can scratch, hit or bow. A developer edition of our first product will be presented at Superbooth: Digital sound designers can get touch information and vibration via USB. For analog synthesis it can output CV for x, y, gate and additionally the vibration signal."
