Talking Filters | Schlappy Patching with Stazma

video upload by SCHLAPPI ENGINEERING

"Episode 6 for Schlappy Patching!
Do you know how to make filters talk? It’s fun and one of my favorite patches to do with modular synthesizer, because of the amount of control you can have on the talking.

In this new episode of Schlappy Patching I’ll give it a go with the 100 Grit and Angle Grinder, the two filters of the Schlappi Engineering echo system.

Do you have a favorite talking filter?
Have fun watching!"

Eric Schlappi and Bastien Lavaud - Orbital Mirrors

video upload by SCHLAPPI ENGINEERING

"Part of an improvisational audiovisual jam session between Eric Schlappi and Bastien Lavaud on August 26th in Grenoble, France, lightly edited afterwards.

Audio is Eric Schlappi using a prototype of the Nibbler as a crude sequencer and another Nibbler at audio rate dividing down the lead synths frequency to create the bassline. The lead is a Three Body and the Kick is formed with the Angle Grinder and Boundary modules. There are also some overdubbed blasts of noise using a Nibbler at audio rate with the shift register functionality.

Video is Bastien Lavaud using a mix of @syntonie1487 (including the upcoming Solaire and Seuils modules) and @lzxindustries video modules as well as some video feedback through a camera.

Please watch in the highest available quality as compression is quite harsh on the video synthesis methods used.

Schlappi Engineering ANGLE GRINDER / ingenious vco, lfo, filter & distortion / extensive playthrough

video upload by BRiES

"In this video about Schlappi Engineering's ANGLE GRINDER I demonstrate the different aspects of the module seperately, before throwing it all together in a gritty mayhem of waveshaping and feedback.

ANGLE GRINDER is a versatile piece of gear that can be used to create, shape and mangle audio as well as CV signals. The filter sounds really nice and clean if you back off all the feedback and modulation, but once you start adding the GRIND section to the mix it can produce rich CV controllable distortion. If you use ANGLE GRINDER as a VCO or LFO the linear and exponential FM inputs provide plenty of modulation options. The quadrature LFO outputs can bring life to patches and by adding feedback you can change the shape of the generated sine waves drastically. You can even use ANGLE GRINDER as a make-shift sequencer."

"The behaviour of the comparators is starting to make sense... but it all falls to pieces from the moment you introduce feedback (which is very easy due to the normalized connections).

I'm getting closer to being able to do a full video about this module."

Korg opsix- Dream vs Nightmare, external modular processing for a simple organ-like patch

video upload by Friendly Noise

"Modules: Xaoc Tallin, Schlappi Engineering 100 Grit and Angle Grinder, SSF Vortices, Intellijel Quadrax.
No eurorack: Strymon Nightsky

Preset used: 014 Ambi Sines. Internal filter and effects are off. The monophonic output goes into Xaoc Tallin for level raising and then the signal goes to 100 Grit for filtering and distortion. The output from 100 Grit goes into the Angle Grinder, where it gets splitted using the dedicated output for low pass and high pass filtering. The splitted signals go to two mono channels of Vortices. The panning of those two channels is modulated with channels 1 and 2 of Quadrax in LFO mode (but not from the beginning of the video). The idea is similar to what a Leslie does, but not trying to emulate the sound. Channels 3 and 4 of Quadrax are also in LFO mode and modulate the filter frequency of 100 Grit and Angle Grinder. Finally, Nightsky adds some ambient reverb. No sequencing or arpeggio were used, but sometimes the intermodulation of oscillator frequencies and harmonics would let you think there is some sequencing."

Befaco Noise Plethora Demos by Friendly Noise

Podcast 307: Eric Schlappi

Published on Dec 22, 2019 20Objects

"There are a few modules that have been quietly creeping into discussions - and modular rigs - over the last few months. One manufacturer that keeps coming up is Schlappi Engineering - and especially the Angle Grinder module. I'm not sure how you make a quadrature oscillator sexy - but Eric Schlappi seems to have done it!

In this chat, we go over Eric's background, how he came up with some of his modules, some of the technologies that he's exploring for the future, and his own music-making (and performing) process. His modules are opinionated (in that they have design decisions that can drive you in certain directions), but in a way that can still allow you to maintain your own voice. He also talks about his own obsession with analog monosynths, and how this has influenced his own electronics development.

In addition to his modules, you can check out some of his recorded work on his Bandcamp site (https://ericschlappi.bandcamp.com/). Also, for Tier 2 (and above) Patreon supporters (https://www.patreon.com/darwingrosse), we have an extended interview about the performative aspects of the 100 Grit that is particularly interesting.

Enjoy!"

Schlappi Engineering Angle Grinder & Interstellar Radio

Published on Dec 12, 2018 Perfect Circuit

"Schlappi Engineering has two gritty and noisy eurorack modules. The Angle Grinder (https://www.perfectcircuit.com/schlap...) is a quadrature oscillator and filter with built in complex feedback paths for squaring up and distorting the signal. The Interstellar Radio (https://www.perfectcircuit.com/schlap...) modulates and then demodulates a signal with the options of adding lots of odd aliases from the transmission. This patch is sequenced with Noise Engineering modules, the Integra Solum, Mimetic Digitalis and Zularic Repetitior. The Sinc Iter is used as the sound input for the Interstellar Radio to create a noisy snare sound. The Mutable Instruments Stages is used as five envelopes to modulate the bass sound of the Angle Grinder. Intellijel’s Quad VCA is used as VCAs and Mixers and the WMD/SSF DPLR adds a delay effect to the snare sound.

Schlappi Engineering Angle Grinder Eurorack Module

Angle Grinder eurorack module demo (the basics) Published on Sep 24, 2018 SCHLAPPI ENGINEERING

"An introduction to the basics of the Schlappi Engineering Angle Grinder eurorack synthesizer module. It is an all analog quadrature VCO and waveshaper module, more details can be found at:

via Schlappi Engineering

"Angle Grinder is a quadrature sine wave oscillator, filter, and distortion effect.
The SPIN section is a quadrature sine wave oscillator. The GRIND section compares each phase against the input signal, then subtracts the resulting square waves from the input signal. If the spin section is either damped enough or enough signal is fed into it from the GRIND section then it will stop oscillating and become a state variable filter.

The Angle Grinder tracks volts per octave and can be used as a sine wave oscillator with voltage control over harmonic content available at the GRIND OUT. With no input it’s four phase related sine outputs (0°, 90°, 180°, and 270°) remain clean from 0.1Hz to over 20kHz and are suitable for quad panning or XY applications.

With an input signal applied the GRIND out ranges from quadrature pulse width modulation (at LFO rate) to sync-like metallic tones (at audio rate). When GRIND is fed into the SPIN then it becomes a nonlinear feedback network with the faders and corresponding CV inputs providing instinctive control over phase cancellation, oscillation, and distortion. The four phase related outputs will become low pass, band pass, high pass, and inverted band pass filter outputs.

The function of the Angle Grinder depends on both the position of the knobs and the presence of an input signal.

Quadrature Sine wave VCO with four phase related outputs: 0°, 90°, 180°, 270°
HIGH range from 10Hz to over 20kHz
LOW range from 0.1Hz to over 500Hz
Tracks volts per octave at the V/OCT input
FM1 is selectable linear or exponential FM via jumper on back
FM2 is additional exponential V/OCT jack
With no input GRIND section provides voltage controlled harmonic content
With input GRIND section compares each phase against GRIND IN signal
