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!!"

"Episode 20 for Schlappy Patching!

For this one we have a guest of honor, the 259t by Tiptop Audio & Buchla, wich make for a great time to talk a little bit about 'complex oscillators'.
We will compare the Three Body and the 259t to see and hear how different they are and we will make some music and noise with both of them.

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!!"

Machina Bristronica 2024

Playlist:

1. Bristronica 24: MyVolts The Silent Alchemist Nears Shipping

We caught up with Caroline who gave us the latest update to the *Silent Alchemist*, a versatile power hub designed for musicians. Featuring five isolated USB-C outputs and a high-wattage sixth output capable of delivering 100 watts, the device can power a Mac with the remaining outputs providing 20 watts each. Its independent circuits ensure noise-free operation, catering to a variety of devices including the Dreadbox module and Sysmo slope generator.

The Silent Alchemist uses innovative step-up power tips to convert USB-C input to the correct voltage for various devices. There's also new feature: an uninterruptible power supply allowing seamless transition between wall and power bank sources. Also introduced were updated cables, such as silver candy cords and floating ring TRS to TS cables, expanding connection flexibility. The Silent Alchemist is expected to be available in December with a competitive pricing strategy.

2. Bristronica 24: Circuit Happy ML2M Clock Sync module updates

At Bristronica 2024, we caught up with the creator of the *ML2M*, who introduced us to the latest version. The ML2M is a compact Eurorack module with Wi-Fi capabilities, allowing seamless synchronization with Ableton Live, Bitwig Studio, and iOS music apps using Ableton Link without the need for cables. It either connects to an existing network or creates its own, ensuring robust sync even in environments with unreliable Wi-Fi. The module, which retains its 2HP size, now features MIDI integration through TRS jacks. Users can access a web interface to configure each output for different clock divisions and reset triggers, making setup straightforward and flexible.

Alongside the ML2M, there's also the Missing Link Junior. This desktop version offers the same functionality but in a box format, complete with MIDI and CV clock outputs. Both products are now accessible, with a starting price of $250.

3. Bristronica 24: Archaea Exchange Patching Module

At Machina Bristronica 2024, we caught up with Arran from ‪@archaea_modular_synthesis‬ who presented the *Exchange Module*. This programmable patcher, a year in the making, evolved from its early prototype stage to a fully functional module. Arran explained how the Exchange can route synth voices via a beam controller and three exchange modules installed within the skiff, allowing for versatile patching. Operating like a matrix patchbay, it enables users to select inputs and outputs with the push of a button, create presets, and chain multiple modules for synchronized patching.

Communication between the modules occurs over the Eurorack power bus as well as over MIDI via the USB-C connection. The Exchange maintains analog integrity, ensuring there’s no conversion latency. The forthcoming release expected in late November 2024, includes a USB-driven editor for enhanced control capabilities.
