"We say... A pre-owned Sequential Trigon-6 in very good condition. It comes with original packaging and power cable
Manufacturer's description Experience the Power of Three Oscillators and a Ladder Filter with the Trigon-6 Module
The Sequential Trigon-6 desktop module delivers the same massive sound and hands-on sonic control as the Trigon-6 Keyboard. It features the same pure analog signal path with discrete oscillators and filters, and the same high-quality digital effects. It also has the same intuitive layout with full-sized knobs and switches that make it quick and easy to shape new sounds.
The Trigon-6 module sounds huge — just like the keyboard, because it is the same six voice polyphonic instrument, just in a smaller form factor. And if you want even more polyphony, you can use the poly chain feature to link any two Trigon-6s for a stunning twelve-voice synth!
A Sound That is Bold and Familiar
The Trigon-6 is Sequential’s polyphonic take on the classic, thick and creamy, 3-oscillator-plus-ladder-filter analog sound that defined the dawn of the synth era. It’s a sound that bridges genres and styles — now refined and redefined with Sequential’s own modern imprint.

"The first synth I've needed the manual to understand whats going on
What happens when a synthesizer throws away the traditional signal path and replaces it with logic gates, chaotic modulation and experimental sequencing? The Neutral Labs Luna is a modern Lunetta-style synthesizer that turns digital logic into sound – and it’s one of the most unusual instruments I’ve explored.
In this video I take a deep dive into the Luna Lunetta synthesizer, exploring how it works, why its architecture is so different from traditional subtractive synths, and how you can use its oscillators, logic circuits, modulation sources and built-in sequencers to create strange, evolving patterns and glitchy electronic textures.
Lunetta synths are inspired by DIY digital logic circuits built from CMOS chips rather than classic VCO-VCF-VCA designs. The result is a unique sound world somewhere between modular synthesis, generative sequencing and experimental electronic music.
We'll explore:
• What a Lunetta synthesizer actually is
• How the Neutral Labs Luna architecture works
• Using the dual oscillators and internal 64-step sequencers
• CV, gates and creative routing possibilities
• Generative patterns, glitches and chaotic rhythms
• Why Lunetta synths sound so different from traditional analog synths
If you're interested in experimental synthesis, modular workflows, generative music, CMOS logic synths, or unusual electronic instruments, the Luna is a fascinating machine.
Whether you’re a modular user, synth enthusiast, or just curious about alternative synthesis techniques, this instrument shows how far you can push sound design when you break the normal rules."
"This listing is for a vintage 1980's Ensoniq ESQ-1 Analog/Digital Polyphonic Synthesizer Workstation that comes with an Ensoniq Sequencer Expander Cartridge and power cord. This synthesizer is in good physical and working condition. The winning bidder will receive exactly what is pictured.
The Ensoniq ESQ-1 is a 61-key, velocity sensitive, eight-note polyphonic and multitimbral synthesizer released by Ensoniq in 1985. It was marketed as a "digital wave synthesizer" but is actually an early music workstation. Although its voice generation is typically subtrative in much the same fashion as most analog synthesizer that preceded it, its oscillators are neither voltage nor digitally controlled, but true digital oscillators, provided by a custom Ensoniq wavetable chip. The signal path includes analog resonant low-pass filters and an analog amplifier.
I’m beyond excited to introduce you my "No talking demo" of the Donner Essential L1 — a fully analog, monophonic subtractive synthesizer inspired by the legendary Roland SH-101.
In this video, you’ll hear the raw sound of the instrument with no voiceover and no unnecessary processing — just pure analog tones, basslines, sequences, leads and textures created directly from the synth.

Press release follows:
Cherry Audio has announced SH-MAX, an innovative software synthesizer that integrates three legendary SH-series synths from the '70s: the SH-5, SH-7, and SH-3A.
Cherry Audio has announced the launch of SH-MAX, an innovative software synthesizer that integrates three legendary SH-series synthesizers from the 1970s: the SH-5, SH-7, and SH-3A. SH-MAX captures the bold sound of the SH-5 while incorporating features and aesthetics from the other models, enhancing the original designs with greater power, versatility, and essential tools for modern music production. Musicians and vintage synth enthusiasts can start using SH-MAX today for the incredibly low price of just $59, available at cherryaudio.com and authorized resellers worldwide.
SH-MAX faithfully recreates the vibrant tones and workflow of the original SH hardware. It features powerful dual oscillators, two LFOs and ADSR envelopes, the dual-parallel multimode and bandpass filter sections, and the five-channel mixer of the SH-5 (1976), plus a ring modulator and sample/hold capability. Also included are autobend, duophony, filter FM, and the syncable VCOs with additional waveforms found in the SH-7 (1978). The extra additive-style oscillator from the SH-3A (1975) further enhances sound design flexibility. Moreover, SH-MAX incorporates and expands upon the expressive touch performance of the SH-2000 (1973) and features an onboard sequencer inspired by the Model 104 of the legendary System 100 semi-modular synthesizer from 1975.
SH-MAX honors its lineage while taking full advantage of modern software capabilities, supporting mono, duophonic, and 16-voice polyphonic operation for rich chords as well as earthshaking unison timbres. It features three unique retro interface themes that pay homage to the aesthetic of the SH-3A, SH-5, and SH-7, providing a visually immersive experience for true vintage synth enthusiasts. Additionally, optional drift and slop controls for the oscillators, filters, amp, and dual envelope generators introduce authentic analog character and warmth to every sound patch.
The highly flexible SH-style stereo mixer and its varied workflow options allow for modular-style signal routing. Each sound source -- VCO-1, VCO-2A, VCO-2B, the ring modulator, and noise -- can be independently routed to the VCF, BPF, or VCA, with each path enhanced with its own chain of studio-quality effects. With 20 effects available to arrange and reuse within its four chains, SH-MAX provides an exceptionally wide sonic palette. Additional features include a four-channel step sequencer capable of parallel playback or extended chaining, along with a touch effects panel that supports channel and polyphonic aftertouch with compatible MIDI controllers.
SH-MAX's legacy traces back to over five decades of synthesizer and electronic music innovation. The SH-series synthesizers have been used by a diverse range of artists, including Kraftwerk, Tangerine Dream, Jean-Michel Jarre, Brian Eno, Gary Numan, Throbbing Gristle, Skinny Puppy, Aphex Twin, Orbital, Mathew Jonson, Pink Floyd, Nine Inch Nails, Kitaro, MGMT, Vangelis, The Human League, Blondie, Yello, and more.
With SH-MAX, users can create everything from massive leads and thick basses to lush pads and exceptional sound effects, making it a true synthesis powerhouse at their fingertips. To inspire musicians right out of the box, SH-MAX includes over 300 expertly crafted presets that showcase its broad capabilities.

A COMPACT ANALOG COMPRESSOR
Messor is a fully analog stereo feed-forward VCA compressor designed for studio, modular, and live systems. The architecture is derived from the original Cosmotronic eurorack module, with extended headroom, improved channel matching, and a revised sidechain topology optimized for wide dynamic ranges.
HIGH HEADROOM
The internal ±12 V regulated power rail provides substantial headroom and consistent operating conditions for both line-level and modular-level sources. It reliably handles high-transient material from synthesizers, drum machines, and percussion-heavy sources without premature clipping. High-impedance inputs and balanced outputs simplify interfacing with modular systems, samplers, and balanced studio equipment.
Signal flow begins with a low-noise stereo preamplifier offering up to 18 dB of gain, followed by a pair of matched VCA control blocks. The feed-forward topology provides predictable transient behavior, accurate envelope shaping, and stable stereo imaging. A post-VCA conditioning stage adds tube-like saturation, introducing controlled harmonic content when driven into overload.
"As the second synth in the 'Super' series, the Gemini represents a quantum leap in UDO's technology – building on the acclaimed rich sound pioneered by George Hearn and the Super 6. Adopting a true-stereo Binaural signal path with dual FPGAs and twin effects processors, Gemini will take you on an adventure of spectral dynamics, of glittering frequency and shattering subharmonics, of comfort and discord, expectations and surprises."
"Coming in hot after Hieroglyphic's first release 'Plume' here we have OPALINA which is a stereo spectral playground. It's billed as a filter network, with triple band pass resonator modes and an isolator multi mode network. It has multi band outputs for creative modular processing, with the including expander it also has specific (and stereo) low mid and high band inputs. Loads to go at, but distilled down into exploring 3 patches here for our 3 PATCHES series of videos."

"Magnolia is an eight-voice analog through-zero linear FM synthesizer. Besides the classic analog polysynth sounds, its design allows programming some less conventional timbres closer to the world of modular synthesizers, and especially of the so-called “complex oscillators.”
Magnolia allows to bring modular synthesis techniques in the world of analog polysynths, with all the known advantages of the latter: polyphony, immediacy of use, powerful sound, and those little unpredictable details generally known as “analog warmth.”
Magnolia is a highly playable instrument thanks to its expressive Fatar keyboard with polyphonic aftertouch and encourages sound exploration through its large and relaxing front panel.
After sculpting sound in space with The 3B, The 3FX explores the creation of sound spaces capable of transcending all your instruments.
ARCHITECTURE
The heart of The 3FX is built around three fully independent effect voices, each based on a coherent 8-module architecture:
Two delays per voice, usable in series or in parallel An advanced, progressive feedback path up to controlled self-oscillation An analog 12 dB/octave multimode VCF (BP, LP, HP) to optionally process the audio spectrum, both on the delay lines and on the dry signal Independent levels for the dry signal and each delay line A panorama control to position the voice within the stereo field. The stereo input signal is distributed across the three voices: left / left + right / right. A mono signal is distributed across all three voices. Each voice can be used alone, stacked or combined with the others to create textures impossible to achieve with a conventional delay.
"The Sequential Fourm looked limited on paper, but after a month in the studio, my perspective has completely shifted. In this Fourm review & demo, I’m moving past the specs to focus on 4 performance demo songs that showcase the unique tactile experience of this 4-voice analog synthesizer.
The combination of a 100% analog signal path and Polyphonic Aftertouch makes this one of the most expressive instruments Sequential has released in years. Whether you are scoring for film or sound designing from scratch, the Fourm demands a different approach to synthesis.
