Nexus - New Generative Sequencer for Norns // Nymphes // Oto Bim & Boum // Chase Bliss Onward

video upload by Lesjamusic

"Nexus is here. A generative chord-based sequencer for monome Norns that I've been teasing in recent videos.

In this demo, Nexus is driving a Dreadbox Nymphes via MIDI. The signal chain: Nymphes → Oto Bim → Oto Boum → Chase Bliss Onward → Chase Bliss CXM 1978.

Nexus lets you select from a 15-chord diatonic palette while a probabilistic engine triggers notes from within each chord. Two rows on the Grid let you play along in the current scale. There's also bass and sub-bass sequencers that fire root notes on chord changes.

The script outputs MIDI and Crow CV/Gate - so it'll work with pretty much any setup.

Polynomial - Norns Synthesizer built with AI // Oto Bim & Boum // Chase Bliss Onward

video upload by Lesjamusic

"Polynomial - a new phase modulation synthesizer for Monome Norns featuring Chebyshev polynomial waveshaping, instability systems, and deep modulation capabilities.

Built using Claude code. This 24-minute piece explores the sonic range of Polynomial through its preset system, moving between clean melodic tones, textured drones, glitchy rhythmic patterns, and layered ambient soundscapes.

Signal Chain:
Monome Norns (Polynomial) → Chase Bliss Onward → Oto Bim → Oto Boum → Chase Bliss CXM 1978

The performance uses Polynomial's 12-preset Grid system to shift between radically different tones - from warm pads to aggressive leads, chaotic textures to pristine bells. Long delay times on the Onward allow sounds to layer and evolve, while quick preset changes create glitchy, stuttering textures.

Polynomial Features:
Phase modulation synthesis with 4 operator waveforms
40 Chebyshev polynomial transfer functions for harmonic shaping
Multimode filtering with envelope and keyboard tracking
Dual LFO modulation with chaos/feedback control
Instability system for organic variation
Sub-oscillator, noise source, lo-fi bit crushing
Grid interface for instant preset switching
Arc interface for gestural parameter control
Animated particle field visualization

Release:
Polynomial will be available soon for Monome Norns.

Djupviks Modules // Cosmos // Slöer // SH-101

video upload by Lesjamusic

"Off screen, the SH-101 is acting as the sole sound source. That's fed into both DJupviks phasers (The Qu and Neo Tokyo), which are modulated by Bristol Bloodhound Mk 2 and Tangram. Bunker Archeology smears it all up. Soma Cosmos and Walrus Audio Slöer make everything dreamy again."

Borderlands Granular // Tetrax // Wsyn // Dradd // Data Bender // Just Friends

video upload by Lesjamusic

"I often find myself using Borderlands Granular on the iPad as a sketech pad for new ambient compositions. It's such a great use of the screen and the touchpad - it might just be my favourite granular instrument.

I wanted both Mannequins modules to run through Shakti and Dradd, and so I realised that Quadratt could be used as a small submixer too - super helpful.

Here's what's happening:
Borderlands Granular ➡️ Xcelon
Norns ➡️ Wsyn ➡️ Quadratt ➡️ Shakti ➡️ Dradd ➡️ Xcelon
Nerdseq ➡️ Just Friends ➡️ Quadratt ➡️ Shakti ➡️ Dradd ➡️ Xcelon
Tetrax ➡️ Data Bender ➡️ Xcelon
The Xcelon send and return channels go to Sealegs and Bib. Playfader controls p1 and p2 on Dradd, which is in granular mode"

Will It Ambient? Neutral Labs Elmyra 2

"Welcome to 'Will It Ambient?', a new series of videos directly inspired by ‪@collectoremitter‬ 's 'Will it Shoegaze?' series. First up is an easy 'yes!' - the Neutral Labs Elmyra 2 drone synth. I bought this synth today from Elevator Sound, and wanted to get straight to the heart of the face melting. Help is here from ‪@ChaseBlissAudio‬ Mood MK II, ‪@somasynths‬ Cosmos, and ‪@GoPlayAllDay‬ PlayFader.

Sidraxia! Glitch inputs go wild with Palmelund Controller 🎮🎛️🤘

video upload by LesjaMusic

"The Sidrax glitch inputs, according to the manual:
'Two green jacks, that are 'glitch' inputs. They cause the boundary conditions of each oscillator to wire to the output of another. A modulation inspired by circuit bending.'

If you modulate the oscillator that is wired to the one with the glitch input (if you get my drift), you can get wild results. Off screen, Microcosm and Cocoquantus add to the fun.

Djupviks Gats // Grainy Reverb // Angry Filter

video upload by Lesjamusic

"‪@vikingsade‬ Djupviks Gats is a grainy reverb feeding into a wasp-style bandpass filter, with sample-and-hold modulation built into the signal path. By default, it samples your incoming audio to modulate the filter cutoff - creating stepped, glitchy textures that respond to your playing dynamics. The offset control lets you shape that response from aggressive ducking through to keeping the filter permanently cracked open.

In this video I walk through the module and show a couple of patches demonstrating what it can do.

Features:

Grainy reverb into wasp-style bandpass filter
Internal sample-and-hold with adjustable clock
S&H can sample audio or external sources
Bipolar offset control for shaping filter response
Pre/post feedback switch
External clock sync"

Djupviks Spektrum // What is a 'Switch Capacitor Filter'?

video upload by Lesjamusic

"🎛️ Djupviks Spektrum: The Filter That Clocks Itself 🎛️

Spektrum isn’t just another Eurorack filter. It’s a switched capacitor stereo filter that uses your input signal as its clock, turning audio into rhythmic glitches, stutters, and pulsing textures you won’t find anywhere else.

In this video, we break down:
✅ What a switched capacitor filter actually is (in plain English)
✅ How Spektrum turns your audio into patterns and sequences
✅ The unique stereo behavior and control layout
✅ Patch examples to unleash Spektrum’s chaotic beauty

Spektrum reacts to everything you feed it — arpeggios become glitchy basslines, noise turns into crunchy percussion, and waveforms transform into evolving rhythmic patterns.

If you’re looking to add a truly unique, reactive, and chaotic filter to your rack, Spektrum might just be the perfect machine.

Spektrum is available to buy as a kit from Thonk in the UK and Europe, SynthCube and Modular Addict in the US. SynthCube will be stocking some pre-built versions soon too.

Elmyra 2 // cLFO // Microcell // Cosmos // Poly 2

video upload by Lesjamusic

"Following Thursday’s fun playing the Elmyra directly, I wanted to try triggering a sequence. I’m using the Polyend Poly 2 to split the midi from Keystep over 4 CV/gate outputs - hence the spaghetti of wires dangling from the big case. Atovproject’s excellent cLFO is modulating various parameters on Elmyra, keeping the drone evolving. Microcell and Cosmos for texture.

Off screen, CXM 1978 and OTO Boum finish things.

SH-101 // Djupviks The Qu // Sealegs // Gliss

"Djupviks The Qu proving it can do traditional phaser sounds as well as maniac dirt.L, with the help of Bela Gliss on modulation.

SH-101 reminding me no matter how many VCO/VCF/ADSR combos I buy, it’s still the ultimate monosynth.

Apologies for the sloppy playing - I’m better at programming synths than playing them.

Dirt and colour from Sealegs, Gen Loss, CXM 1978 and OTO Boum."

"Pladask ROM is the Eurorack sibling of the Stereo Dradd — a reverb that doesn’t simulate real spaces, but invents new ones. Closely related to Pladask's DRAUME pedal. With three algorithms (HALL, FRAME, GRAIN), clock control, random modulation, and stereo unpredictability, ROM excels at turning static sounds into restless, living textures.

If you enjoy experimental sound design, modular weirdness, and reverb that goes beyond realism, ROM is a perfect tool for your rack."

Introducing Mörser: Djupviks’ Stereo WASP Filter with Digital Noise // Part 1

video upload by Lesjamusic

"Part 1 of a 2 part series introducing the Mörser filter from ​⁠​⁠​⁠‪@vikingsade‬ Djupviks Elektronik.

Mörser takes the wildest analogue synth filter from the the EDP Wasp, and dials up the noise, grit and chaos to 11. In stereo.

Mörser is a stereo filter with low pass, band pass, independent resonance and shared cutoff (and CV). There’s distortion outputs for some extra gnarl, and a clocks digital noise source, hardwired to both the inputs and the CV.

This video explores the basic sounds and functions paired with an analogue VCO. I’ll share a video next week with some more creative patching and different sound sources."
