"This is the Schlappy Minute.

Today I quickly show you how to use the Angle Grinder as a four phase sine wave LFO, also know as a quadrature LFO, to add life into a simple drone patch."

ELECTROID Schlappy jam

video upload by SCHLAPPI ENGINEERING and Stazma

"Schlappy Funk Saturday!

Heavy crunchy feedback phase modulation tone and parallel, stereo, dual Bandpass filter patch to add some vocal life to the thing.
Resetting the Nibblers manually once in a while will give some new patterns to the filter modulation.

Classic 880 on the beat and syncing everything.

FLOW 3 / LANCER'S LASH / EDDY / a handful of new modules / first patch

video upload by BRiES

"I just installed Shakmat's new snare voice into my rack - it is pretty awesome. I thought it would pair up nicely with Flow 3 as a kickdrum and Eddy for side-chaining the synths. I was right."

Filters go Wouahouh

"Schlappy Patching 2026 EP.17

Hey there!
Today I want to show you how to make vowel sounds with some parallel filtering technics. You'll need to run your oscillator to three frilter, on Low Pass and two Band Pass and mix these in parallel, then apply the modulation you want to all of them.

Let's Schlappy Funk!!!!
Have fun!!!!"

"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!!!!"

Waveform mixing with Eddy

"Ever tried Eddy as a waveform mixer?

Plenty of options in there to mix and mangle your oscillator’s waveforms.

Have fun !"

Subtle Expressions: Squarp Instruments Hapax Performance

"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

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.
