"Schlappy Patching 2026 EP.11

Hey there!
Today I wanted to make a weirdo fast IDMish drum patch (and I did) but I accidentaly turned it into a weird dub mess that was MUCH better than what I intended hahaha. So come along for a fun modular journey with me.

Have fun!!!!"

Have fun!!!"

SCHLAPPI ENGINEERING Introduces new Eddy and Cascade Eurorack Modules

Overview video upload by SCHLAPPI ENGINEERING

"Eddy is a three channel stereo CV controlled mixer with sidechaineable compression and distortion, designed as a compact submixer. It also has normalized feedback paths for more experimental tone shaping, no input mixing, and percussion synthesis workflows.

The Cascade expander allows access to the individual VCA outputs for use as a triple stereo VCA as well as access to the feedback filter outputs and simultaneous clean, compressed, and distorted bus outputs for additional mixing and processing options."

01:02 Mixing/VCA basics
02:20 Sidechaining
02:50 Feedback and percussion patching
04:33 Gain amounts and headers
04:45 Cascade expander
06:00 Using as compressed drum submixer

12:00 Jamming even harder

Eddy & Cascade - Triple stereo VCA and feedback machine

video upload by Stazma

"New Schlappi Engineering module alert!!!!
Welcome Eddy and it's expander, Cascade.
Eddy is a three channels stereo VCA and mixer, with normaled tuned feedback paths, mute and phase invertion switches, compressor and distortion modes and more.
The Cascade expander allows you to tap different outputs of the circuit individualy for parallel processing or feedback patches."

How to patch evolving textures

video upload by SCHLAPPI ENGINEERING and Stazma

"Schlappy Patching 2026 EP.3

Hey there!
Today I'll show you how to create evolving textures using the three oscilators of the Three Body and modulate their phase or FM indew with a Boundary Layer.
We will explore very slow modulation as well as more rhythmic behaviours during the video.
Have fun!!!"

How to MAX & MIN

video upload by SCHLAPPI ENGINEERING and Stazma

"Schlappy Patching 2026 EP.2

Hey there!
Today I'll show you some interesting and useful ways to use the Max & Min outputs of the Boundary Layer to create complex envelopes and modulations.

BTFLD ... IN STEREO

video upload by SCHLAPPI ENGINEERING and Stazma

"Schlappy Patching 2026 EP.1

Hey there!
Today I'll have a go at using two BTFLD for stereo sound processing and show some modulation strategy to make it sound even MORE stereo. It's quite crazy all the weird and harsh tones you can get out of it feeding just a simple triangle wave to it.

Have fun!!"

"Granular" Filter Trick - Klavis Mixwitch

video upload by Stazma and SCHLAPPI ENGINEERING

"Roll your own 'granular' filter!

All you need is a sequencial or adressable switch to plug various outputs of any multi mode filter into it and then run it at audio rate. I'll show you how to patch this with the Klavis's Mixwitch and Schlappi Engineering's Angle Grinder.

It worked and here is how!"
