Analog oscillators hit different: exploring the SED-CSM and QSQ

video upload by SynthDad

"I dive deep into the raw sounds and harmonic richness of the SED-CSM, a complete analog synth voice from Rides in the Storm. With its dual oscillators, sub-octave generator, ring modulator, and a dedicated noise source, this module provides a massive foundation for everything from earth-shaking bass to evolving drones.
SED-CSM has two LFOs which can go into audio-rate, reaching up to 6.6 kHz and a VCF equipped with a dedicated overdrive switch. The SED-CSM offers endless possibilities for aggressive textures and squelchy, acid-inspired leads.
Complementing this is the QSQ; an 8-channel performance sequencer and MIDI-to-CV interface that serves as the brain of the operation. I show how the QSQ’s 16 analog-style rotary encoders allow for intuitive, hands-on melodic creation. Leveraging features like Euclidean rhythms, per-step probability, and integrated LFO/envelope generation, the QSQ compliments SED-CSM’s raw oscillators.

Luna is the most LOGICAL synth in the world

video upload by Oscillator Sink

"The Luna from Neutral Labs is an instrument built on binary logic.

Taking inspiration from the DIY Lunetta synths of the 70s and 80s, Luna’s core architecture is built using CMOS chips, square waves, logic gates and binary processors. Its design leads to a semi modular instrument where rhythm is just harmony slowed down. Oscillators can be clocks, and the logic gates and binary processing modules can be involved in modulation and sequencing, or as audio processors depending on how fast you work them.

Luna supplements these binary ideas with a number of additional features which take it beyond the Lunetta synths of old, like pitch quantization with multiple scales, pitch sequencing, MIDI control and digital effects, as well as a three channel output mixer with low-pass gates.

In this video I’ll go through the various fundamental sections of Luna, demonstrating how they can be used to influence the synth, both at sub-audio-rate for sequencing and modulation as well as at audio-rate as sound processors, and then move on to a few full patches to explore how everything operates together. Throughout the video I’ll scatter a few other patches of various types to give you an idea of the range of the Luna in different musical settings.

Transparency notice: Neutral Labs Kindly sent this instrument over to me for free for the purposes of making videos about it."

Genki KATLA - THE VOLCANO SYNTH!! Now Available

video upload by Starsky Carr

"What happens when a synthesizer completely breaks the rules?
In this video, we explore the Genki KATLA — a truly unique polysynth inspired by Icelandic volcanoes, featuring a rotating voice architecture, hybrid signal path, and some of the most unpredictable sound design possibilities I’ve come across.

This isn’t your typical analog polysynth. Each of the five voices can run independently with different waveforms, octaves, and modulation — creating evolving textures, harmonic movement, and generative-style sounds that feel closer to modular synthesis than traditional keyboards.

🎛️ What makes the KATLA special?
• Rotating voice polyphony (round robin-style synthesis)
• Independent per-voice oscillators & tuning
• Digital oscillators + analog filter signal path
• Looping envelopes reaching audio-rate modulation
• Phase distortion, wavefolding & multiple distortion types
• Tape-style wow, flutter & pitch instability effects
• Stereo voice movement & evolving spatial modulation
• External inputs for processing other gear

From lush ambient pads to aggressive, evolving sequences — this synth can go places most instruments simply can’t. It’s not about recreating vintage sounds… it’s about discovering entirely new ones.

💸 At around €5000, this is definitely not a beginner synth — but for sound designers, and anyone looking for something truly different, it well worth a look."

"Hey guys! Very very excited to be presenting the Genki Katla to you all... I am truly in awe of the sound of this very unique and powerful instrument.

I thought the best way to get to know the synth is to start from scratch so in this video we'll go full hands-on with the Genki Katla, exploring (almost) every parameter and building sounds from an initialized patch.

From some raw drone layers and gritty textures to evolving pads, rhythmic sequences, and atmospheric beds, we will see just what this instrument can do, discover new sounds, and maybe make some friends along the way 🙏

If you're into sound design, unique synths, or just love discovering new instruments, this one is for you!

HUGE thanks to Genki for letting me a part of this with them and showing off this super cool synth.

No money was paid, no agreements were made... these are my real thoughts on this very premium synthesizer and I will be sharing lots more."

Press release follows:


Genki Instruments announces availability of Katla as Voice Rotating Polyphonic Synthesizer inspired by its natural namesake

REYKJAVIK, ICELAND: having twice blown European musical minds thanks to show-stealing showcases at SUPERBOOTH25, May 8-10, Berlin, Germany and Machina Bristronica 2025, September 27-28, Bristol, UK, before adventuring across the pond for a repeat performance at Buchla & Friends 2026, January 24-25, LA, CA, USA, Reykjavik-based instrument developer Genki Instruments is proud to announce availability of the eagerly-awaited Katla as a Voice Rotating Polyphonic Synthesizer inspired by Iceland’s largest subglacial volcano as its natural namesake — readily representing the company’s first foray into analogue synthesis, albeit one that uniquely utilises a set of wildcard parameters to infuse it with organic, unpredictable behaviour as an instrument that is worthy of that legacy, excelling at generating rich, evolving, multi-layered textures, where each note stirs, swells, and erupts in its own distinct way — as of March 31…

Clearly Katla’s inspiration runs through its ‘volcanic’ veins. After all, it is framed by side panels and knobs forged from authentic Icelandic lava, giving each instrument a tangible connection to the volcanic forces that inspired it. That this synth should surely roar is a given. Genki Instruments inevitably chose, therefore, to kit Katla out with four independent distortion destinations, the most unruly of which is a stereo CMOS (Complementary Metal Oxide Semiconductor) Drive effect — a characterful saturation stage, pushing tones from warm and rounded to fractured and snarling.

ARP Odyssey Mk II 2813 with Sub-Oscillator Kit Installed SN 1157

Note: links to listings are affiliate links for which the site may be compensated.

via this eBay listing

"The Odyssey was Arp's competition to the Minimoog in the 1970s. It is a 37-note two-oscillator analog synth, and it has a duophonic keyboard, meaning that you can play two notes at once (for which the Odyssey assigns one oscillator to each note). This Odyssey also has our Sub-Oscillator Kit installed which gives it square-wave sub-oscillators for each of the Odyssey's VCOs, and a control potentiometer for mixing in the amount of each sub. The resulting sound is monstrous!

This Odyssey is a Mk II model 2813 and it is in good condition. It was serviced by our technicians and is ready for many more years of use. It really is a perfect addition to any stage or studio."

When the Spec Becomes Code: Building a Norns Instrument with AI

video upload by Lesjamusic

"Building PolyNexus: A Complete Norns Instrument, using Claude AI

I used to struggle with "vibe coding" - throwing prompts at AI and hoping for working software. Then I discovered the article "When the Spec Becomes the Code," and everything changed.

Spec-driven development (SDD) transformed my workflow. Instead of generating code through endless prompts, I focus on creating clear specifications first. The spec becomes the blueprint, and Claude AI helps compile it into working code.

PolyNexus is the result of this approach - a complete generative polyphonic instrument for Monome Norns that evolved far beyond my initial vision. What started as a chord sequencer grew ambitious: I built PolyVoice, a custom 6-voice synthesizer engine in SuperCollider, based on three Plaits oscillator models with wavefolding, sample rate reduction, and comprehensive modulation.

The best part? Spec-driven development gave me the confidence to tackle SuperCollider synthesis, something I wouldn't have attempted with traditional "vibe coding."

🎹 PolyNexus Features:

PolyVoice Synthesis Engine: • Custom 6-voice polyphonic SuperCollider engine • Three Plaits-inspired oscillator models (morph, waveshaping, wavetable) • Wavefolding for harmonic complexity • Sample rate reduction for lo-fi textures • Independent LFOs and envelope control per voice

Generative Sequencer: • 16-chord harmonic palette (monome Grid row 1) • Probabilistic note retriggering engine • Random chord sequencer for compositional surprises • Bass and sub-bass sequencer for rhythmic foundation • Real-time playable notes (Grid row 5)

Analog-Style Effects Chain: • Tape character: flutter, wow, saturation, tape noise • Tape-style delay with feedback and rate control • Multi-mode filtering for tone shaping

🔗 Resources: • Jean Bovet: "When the Spec Becomes the Code" - / when-the-spec-becomes-the-code • PolyNexus (coming soon to lines community) • monome Norns - https://monome.org • Mutable Instruments Plaits • SuperCollider synthesis language

⏱️ Timeline:
0:00 - Introduction: The Struggle with Vibe Coding
01:51 - Discovery: Spec-Driven Development
04:33 - What is PolyNexus?
12:37 - Live Performance

Want to try spec-driven development? Start by describing what you want to build in clear, detailed language. Iterate on the specification until it's crystal clear. Then let AI help compile it into code. You'll be amazed at what becomes possible."
