"Cherry Audio's Pentaphonic synthesizer revives the ultra-rare polyphonic hybrid synthesizer originally developed by Gleeman Instruments in 1981. With fewer than 70 units ever produced, this synthesizer is legendary for its rich tone, distinctive design, and pioneering sequencing capabilities. This emulation faithfully reproduces the lush sound of its digitally controlled oscillator (DCO) and analog-filter architecture while capturing the visual essence of the synthesizer "made to be seen, not just heard."

https://cherryaudio.com/products/pent... Cherry Audio has taken its capabilities to new heights with expanded polyphony, expressive performance, polyphonic and parameter sequencing, and a library of studio-quality effects. Our visual makeover offers a choice of stunning designs inspired by the various looks it sported during its brief existence."

Cherry Audio Pentaphonic: A rare synthesizer masterpiece reborn

video upload by CatSynth TV

"CatSynth presents a deep dive into the new Pentaphonic from our friends at Cherry Audio. This is a recreation of the extremely rare Gleeman Pentaphonic synthesizer, complete with its unique look featuring crystaline transparent knobs and a translucent body. The Pentaphonic was an analog polyphonic synth with a few twists, including three digital oscillators with microcontroller-generated waveforms that were fed into an analog Steiner Parker filter. We explore the emulation of these unique features as well as Cherry Audio's enhancements for modulation, effects, and motion. We also check out a few of the factory and expansion-pack presets.

UMWELT - Generative Ecosystem Synthesizer (VST / AU)

video upload by Laboratory 0

"UMWELT is a synthesizer made for listening. Press the capsule to generate an autonomous ecosystem with its own weather, tuning, four creature groups, and occasionally a language. Drag across the landscape to rotate the view. Active sounds light up and create ripples, revealing which group is active. The capsules along the top recall recent worlds.

Take your time with each world. Populations grow and decline, day turns to night, storms pass through, and the creatures copy each other's songs with small mistakes, so the same world sounds different ten minutes later.

Snare Legio: Analog-inspired snare voice on the Legio platform

video upload by Noise Engineering

"Snare Legio is an analog-inspired snare voice with plenty of control over the body, noise, and punch of every hit.

Get a Legio module and swap to this firmware today:
https://noiseengineering.us/products/...

Let's start with Decay. This controls how long the body of the snare rings out.

Noise controls the snare-wire character, letting you blend in as much noisy texture as you want.

The Impact switch changes the intensity of the attack, with three levels of punch from softer hits to much harder strikes.

Then there's the Wire switch, changing the tightness of the snare wires, giving you loose, standard, and tight variations on the sound.

And of course, Pitch lets you tune the whole voice, or add some modulation to get a little closer to industrial territory.

You can also press the Pitch encoder to mute.

With the audio inputs, you can bring in other sounds and mix them directly with the Snare's output.

Today your Legio is a snare drum. A quick USB swap and it can become a supersaw, wavefolder, granular processor, or something completely different.

23 Firmwares.One Legio.

Visit noiseengineering.us or your favorite retailer to get a Legio module in your case."

3 ways to get more out of envelope modulation

video upload by Monotrail Tech Talk

"A lot of synths have a two-envelope setup, often modulating the filter and VCA. But with a modular you can add a lot of interesting movement to a sound with creative patching. In this video I go over three different techniques that use a second envelope. To shape the transient. To add movement to the body of a sound. And to experiment with note-off modulation.

"Up for grabs is our Roland JX3p with DT200 controller. It all works fantastic, sounds amazing and looks good as well.. see pics for minor body wear etc.. nothing major, in fact this is one of the better JX3ps I have come across over the years. This synth sounds every bit as awesome as a Juno60 and although it does not have as many features as a Jupiter 6 I still feel that its every bit as awesome and every bit as elegant as the Jupiter 6. Also included is the new DT200 and proper connecting cable.

THIS JX3p has had the battery replaced! This synth was tech'd and given a good check up. This synth is good to go for years to come!"

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.

UVI Introduces Rumble - The First Multiband Bass Synthesizer

Playlist:

1. UVI Rumble | Trailer
2. UVI Rumble | Showcase
3. UVI Rumble | Overview
4. UVI Rumble | Tips & Tricks

"Introducing Rumble, the first multiband bass synthesizer

Now available with intro offer at https://www.uvi.net/rumble

For the first time, discover a synth plugin that offers full control over the spectrum through three bands: Body, Character, and Air. With each band, a complete synthesis engine, achieving unmatched flexibility and precision in bass sound design."

"Rumble was designed to meet the needs of contemporary bass: the weight, punch, articulation, and movement that bass-led music demands. To deliver that, Rumble’s architecture treats each frequency band as a full synthesizer engine.

Body, Character, and Air each carry their own oscillator, wave-shaper, and effects, then converge through a shared filter stage, multiband compressor, and master EQ, to produce a powerful, unified voice.

The result is the first multiband synthesizer, built for bass from the ground-up. Layered sub-, mid-, and high-frequency content stays structurally separate, which means low-end weight, midrange definition, and top-end air can each be sculpted on their own terms.

The architecture itself goes deeper: vocal-formant synthesis, drone textures, percussive transients, cinematic motion, vintage analog warmth, all live within the same per-band approach.

The factory library is built by sound designers and genre-specialized producers, with a sprawling range of presets covering everything from 808s and wobbles to drones, motion sequences, and abstract textures.

Most synths give you one engine. Rumble gives you three."

"This Pulsar is in great working order with its original gig bag, power supply and alligator clips.

PULSAR-23 is an organismic drum machine designed by Vlad Kreimer. It has a semi-modular structure and consists of 23 independent modules. PULSAR can be used for the synthesis of percussion instruments and rhythms, bass and melodic lines, effects and sound landscapes, as well as a source of control voltage and powerful analog FX processor.The PULSAR functions in three different modes: stand-alone, MIDI control and CV control. Moreover, all the above features and control modes can work simultaneously in any proportion or combination.Additionally, PULSAR offers live circuit bending capabilities and the use of the artist’s body conductivity to create patches and cross modulations. PULSAR continues the line of organismic synthesizers begun by LYRA-8, but now in the area of percussion instruments."

"Curves & Membranes is a focused mono synth built around a shapeable Bézier oscillator, two visual modulation systems, and a membrane-based filter. In this full walkthrough I go through the core ideas behind the instrument, how the oscillator works, how the preset morphing and orbital modulators create movement, and how the membrane filter shapes the sound.

The goal with Curves & Membranes was not to make a do-everything synth, but to build something more specific: a synth where sound, shape, and motion are tightly connected, and where the structure stays easy to understand while still allowing a lot of character and timbral movement.

Playlist:

1. Synaptic Resonance | Neural Vocoder Walkthrough

Synaptic Resonance is a neural vocoder-style effect where incoming audio, or an optional sidechain, excites a two-dimensional neural simulation. That simulation is then read back somewhere else and used to animate a bank of forty steep resonant band-pass filters.

In this walkthrough I go through the basic idea behind the plugin, show how the Stim Plane and Read Plane shape the behavior, and explain how the neural controls affect the way the model reacts, spreads, remembers, recovers, and settles.

The core idea is fairly simple: the input excites the model, and the output is affected by reading the model. That is what gives the plugin its character. It can behave like a vocoder, a resonant filter instrument, or something more unstable and alive depending on how it is set up.

Whimsical Raps - Atrium - First Experiment - Completely Wild!

video upload by Richard Devine

"five voices of analog synthesis, controlled and modulated polytimbrally. We’ve taken ideas from our decade of modular exploration and rethought how we reach into polyphony.

Each voice is shaped by its harmonic energy while three core timbre modes push into richer territory. from simple suboctave and noise waves, through frequency modulation, to formant synthesis reimagined. all squeezed through a lowpass/gate combination, providing balance and occasionally emphasis.

no digital multi-effects here, just spectres in the machine. a novel configuration of three filters, two delays, and feedback. front and almost center — this resonant body is meant to be played. sequenceable, modulatable, while feeding back not just sound, but shape for unfolding cybernetics.

and to modulate! everything mappable to everything else, tactile input extended on the fly, mapping as a performance in itself. Sources are dynamically phased across voices and stretched in relative duration. gestures captured into five recorders, extending play rather than overriding it, all twisted in time at your whim.

Atrium is deeply learnable, and for those moments of quick change, instantly recallable. extensible with usb and midi and cv input."

Introducing the Body Synths Laboratory

video upload by Body Synths



"The Body Synths Laboratory is a dual-channel effects processor and feedback synthesizer.

Four feedback paths sit at the core of the Laboratory. Route signals, control delay repeats, or add gritty textures. Push them far enough, and the system enters self-oscillation—even with no input. From there, every control reshapes the feedback into anything from subtle drones to harsh noise madness.

Each channel features three voltage-controlled effects: gain, delay, and filter. Run the channels in series or in parallel. Push signals from silence to amplification with the Gain control. Drive the Delay into dirty territory at longer times—we’ve used that famous karaoke machine delay chip. Combine both channels to create multi-tap or ping-pong echoes.

The Resonant Filter provides Low-Pass and High-Pass modes. Chain the two channels in series to create Band-Pass responses. A final clipping stage at the end of each channel adds compression and distortion when driven to extremes.

We’ve also included a global Modulator that can operate as either an Envelope or an LFO, with two positive and two negative CV outputs. Patch them to build effects like tremolo, vibrato, chorus, moving stereo filter sweeps, modulated delays—it can get pretty wild.

The Body Synths Laboratory is being developed in collaboration with Andrey from the Berlin-based pedal company akkusativ.

Release: 2026. Price: TBA."
