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!!!"

Schlappy #202day jam

video upload by SCHLAPPI ENGINEERING

"It's #202day ! The MC-202 is one of my all time favorite synth so I wanted to build a patch around it using the Schlappy Patching system.
Only the bottom row is used (apart of a Mixswitch to mix the voices).
MC-202 to Angle Grinder for additional filtering.
MC-202 gate out to two Nibblers for drum sequencing and stepped modulation.
Kick drum by two channels of the Boundary Layer.
HiHats by a feedbacking BTFLD in a Boundary.

Have fun!!

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!!"

Beyond the Noise: Synth and Eurorack Performance

video upload by MKustomAudio

"The initial idea of this track started with just ambient noise created by running the Mutable Instruments 'Plaits' through the Schlappi Engineering 'Interstellar Radio'. This noise was further processed and randomized by running the signal through various filters and effects.

After deciding to add in melodic and percussive content, the Moog 'Mother 32' and Novation 'Bass Station II' (AFX overlay used) were then added with sequencing provided by the Squarp Instruments 'Hermod+'. To process the Bass Station II further, it was sent through the eurorack setup using a couple Noise Engineering modules and the Befaco 'Oneiroi'.

The Novation 'Peak', Sequential 'OB-6 Desktop', and Korg 'Minilogue XD' and 'Arp 2600M' were added next to provide bass, melodic and ambient drone content. Last added was some additional drums/samples provided by the Elektron 'Digitakt II'."

"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!"

100 Grit Feedback Tricks - Schlappy Patching 2025 EP.19

video upload by SCHLAPPI ENGINEERING and Stazma

"New year for Schlappy Patching!

Hey there!
Today I'll show you how to patch a voltage controled feedback loop in the 00 Grit so you can control the effect some of normaled connections make by using just an external VCA and a modulation source of your choice.

Have fun!!"

Sequencing a glitchy pattern feat XOR Nerdseq - Schlappy Patching 2025 EP.18

video upload by SCHLAPPI ENGINEERING and Stazma

"New year for Schlappy Patching!

Hey there!
Today I'll show you how I used an external sequencer (XOR Electronics's Nerdseq) to sequencer some glitchy beats and a bassline on the Schlappy Patching system.
This might of interest for those who are curious about how to use an external sequencer with their Schlappi modules.

Have fun!!"

Three Body & FM Algorithms | The Schlappy Minute

video upload by SCHLAPPI ENGINEERING

"This is the Schlappy Minute.

Today I get into how to use the Three Body as a kind of typical FM (Frequency Modulation) tone generator and how to think the three different VCO as operators and 'algorithms'."
