"Schlappy Patching 2026 EP.16

Hey there!
Today I want to show you how to use the BTFLD to multiply the number of events inside a single sycle of a Boundary / Boundary Layer (any function generator). This can be used to create interesting rhythms and can be voltage controlled!

Have fun!!!!"

Subtle Expressions: Squarp Instruments Hapax Performance

video upload by MKustomAudio

"With recently obtaining the Squarp Instruments Hapax to act as my main standalone sequencer, I've been diving deep into all the functions it offers. This is the first track I've made putting together a number of items such as automation, assign controls, creative MIDI effects (register, arpoly, etc.), BPM elasticity, and adjustable start/stop loop lengths. I've added notes in the video explaining some key points for the track and additional equipment used, but below is a more detailed list of the sound sources:

Korg Arp 2600 M
Novation Peak
Novation Bass Station II
Korg Opsix
Sequential OB-6 Desktop
Elektron Digitakt II
Befaco Oneiroi
Soma Lyra-8, Erica Synths Black 3109 VCF/VCA, Qu-Bit Mojave
Make Noise STO + Schlappi Engineering Angle Grinder, Make Noise QPAS, Intellijel Sealegs
Moog Mother 32, Ritual Electronics Miasma (Erica Synths Black Polivoks VCF in feedback loop), Erica Synths Blackhole DSP2"

Drone patching in stereo

"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!!!!"

Eric Schlappi live at DATA/LOSS Gray Area SF 05232026

video upload by SCHLAPPI ENGINEERING

"A live improvised performance by Eric Schlappi at the DATA/LOSS event at Gray Area SF May 23rd 2026. The event was organized and curated by Errorgrid with visuals by Arson Rivvers.

This set had a focus on heavy percussion sequenced by the Schlappi 4 bit ecosystem (Nibbler, BTMX, BTFLD) with an SSF Ultra Kick and Weston AD110 for the actual percussion. Bass and some leads were made with the Three Body, 100 Grit, and another Nibbler generating suboctaves. Delay was 4MS DLD and all compression and distortion with the Schlappi Eddy. Pads and additional leads were a prototype Schlappi desktop polysynth, played by hand with a midi controller.

Using Step 8 with Nibbler and Maths to generate rhythms

video upload by Peter Plugs Patches

"Using patterns from the Schlappi Nibbler to control the current stage of the Joranalogue Step 8, with the Make Noise Math attenuating and offsetting the cv signal to create variations. Sounds are coming from Quad Drum, SSF Entity Ultraperc, Mutable Instruments Plaits, Winter Modular Zaps and Basimilus Iteritas Alter.
