BTMX pattern remix - Schlappy Patching 2025 EP.7

video upload by SCHLAPPI ENGINEERING

"New year for Schlappy Patching! We are no going to upload half of these to Stazma's channel to see if we can get more people to see these patches, so please go over here in two weeks for the next episode: / stazma

In this one we are going to use the BTMX to process a fixed trigger pattern and use the OR logic to add hits to it, so you can play around creating fills by flipping the switches!

Have fun!!"

BTFLD burst generator | The Schlappy Minute

"This is the Schlappy Minute.

Today I show you how to use the BTFLD as a "burst generator", in other words how to feed it signals to extract clusters of gates from them."

Trying to recreate Keith Emerson's sequencer trick of Karn Evil 9

video upload by Frap Tools

"Karn Evil 9 has one of the wildest endings in the history of music-made-with-synthesizers. Many tutorials focused on recreating the sequence note by note, trying to nail the sound, but we wanted to explore the technique to program a sequence that goes faster and faster until it stops. Thanks to the Usta sequencer, it was an easy game!

Original performance mentioned in the video: • Emerson, Lake & Palmer - Karn Evil 9 ... [below]

BTFLD Drum Ratchet & more 4-Bit pattern - Schlappy Patching 2025 EP.6

video upload by Stazma

"Today we will make some drum patterns using the 4-Bit modules once again but in a more predictable way, taking advantage of the reset input on the Nibblers.
We'll also have a look at a very fun way to generate "bursts" or rum rolls kind of pattern with the BTFLD being fed some slopes at it's input!

Have fun!"

Serge Filter Tour | Serge Modular | Episode 07 | Res EQ, VCF2, Siegfried, VCFS, VCFX, VCFQ

video upload by Cinematic Laboratory

"There are currently 1601 filters on ModularGrid. It may be impossible to pick the right one for your case. If we check out the modular pioneers, we'd see Moog's legendary ladder. Buchla only made a rare triple bandpass, Roland and Korg refined far eastcoast synthesis and there are a few exotics like the Wasp and the Polivoks. In this video I want to focus on the Serge filters (eurorack format) which I rediscovered last year. He has five designs with distinct differences. There's the RES EQ fixed filter bank, the VCF2 variable bandwidth with no resonance (?), the VCFS with a variable slope (?) and the highly appreciated VCFQ with variable resonance. A few weeks ago Serge released the VCFX with a 'new gate' on a single panel. It's a simple utility filter on its own, but combined with the gate we'll have a patch programmable LPG. Or a bandpass gate.

I'll be using the Schlappi THREE-BODY as a triple sawtooth voice making a chord. It's a big and nasty sound that could use a filter. It inevitably turned out to be a long video because I had the pleasure to go through five different filters. I tried to keep it fresh and entertaining. Who doesn't love playing the cut-off :)."

Angle Grinder Pings | The Schlappy Minute

"This is the Schlappy Minute.

Today we make lovely percussions with the Angle Grinder!"

BLEND / PHONOGENE piano sample / NIBBLER rhythms and modulation

video upload by BRiES

"The patch is being driven by a pair of NIBBLERS, one as a shift register the other one just as a counter. They trigger drums, create modulation for the 'gene-size' on PHONOGENE, as well as creating the melody for the bassline."

Nibbler & BTFLD combo - Schlappy Patching 2025 EP.3

"In this one we are going back to use the BTFLD as a sub audio buddy to the Nibbler, to create more gates and stepped voltages out of it."

Stereo Rungler and using chaotic sounds in a track - Schlappy Patching 2025 EP.1

video upload by SCHLAPPI ENGINEERING

"In this one we are going back to first ever patch we made last year: the Rungler.
I'll expand on it a little bit, make it stereo and show you a fun way to use chaotic sound as a sound design tool in Abelton Live at the end."

BTFLD Feedback | Schlappy Patching

Schlappi Engineering BTFLD / trying to explain the folding / modulation

video upload by BRiES

"BTFLD by Schlappi Engineering is a unique take on the wavefolding concept, as it uses binary conversion (and clever engineering) to create breaks in the waves without really changing the shape of the slopes. You have to see it otherwise it won't make a lot of sense. That's what this video is about.

At this point I'm really still getting to know BTFLD by ‪@SCHLAPPIENGINEERING‬ but I wanted to share a few insights. Everything was already patched up as I was figuring things out so it made sense to just set up my camera and do a quick video."

Schlappi Engineering Introduces BTFLD

BTFLD Overview video upload by SCHLAPPI ENGINEERING

"The BTFLD (pronounced Bit Fold) can be used as a unique wavefolder or a hands on logic module for generating rhythms from LFOs or envelopes."

Hello BTFLD - 4-Bit audio / cv mangler - Schlappi Engineering

video upload by Stazma

'Today I'll show you some stuff with the new module by Schlappi Engineering, the BTFLD! It's the new member of the 4-Bit logic family by Schlappi Engineering but this one is the most audio oriented as it's main use are wavefolding, fuzz and distortion. It's small but hell it sounds BIG. It can also make weird things to CV and gates, and even be used to convert any signal into 4-Bit so you can use it to modulate / feed your other 4-Bit modules (Nibbler / BTMX)."



BTFLD (Bit Fold) is a distortion, wavefolder, and four bit asynchronous analog to digital converter. The folding output at audio rate provides a hard sync like timbre in a unique sawtooth wavefolder circuit.

The stepped output is a type of bit crushed effect and the square wave outputs provide different frequency multiplications or distortions.

Rhythms can also be generated by putting envelopes or LFOs into the input and using the bit outputs as gates.

It can also be paired with the rest of our four bit binary system (Nibbler, BTMX) for experiments in four bit computing and unusual logic based patching.

Features

6 related outputs
Unique wavefolding circuit
Switched range for bipolar audio signals or unipolar modulation signals
Acts as distortion/wavefolder or rhythm generator depending on input
4 bit binary output interfaces with other logic modules
LED indication for every input and output
6 HP

Ratio Chords with Three Body | Schlappy Patching

video upload by SCHLAPPI ENGINEERING

"Episode 18 for Schlappy Patching!

For this one I'll show you a very unusual way to think chord progressions by using the ratio function of the Three Body, sequenced by the Nibbler / BTMX.
This is a fun way to create sometimes intricate progression without any music theory involved (even tho it can come in handy sometimes), just by listening to what's happening.

Have fun watching!!"
