The Fragmenter 45 is a circuit bent Extron 1604 HDMI Scaler. It is a very high quality unit that demanded a very high retail price when originally released. The HDMI signal integrity is pixel perfect and doesn't compress your image when passed through this thing. It processes 1080p 60fps signals without even breaking a sweat!

This one features some effects that are new to myself, targeting a specific part of the clock circuitry that I have not experimented with before on any other device. The 3 push buttons trigger different clock glitch effects that completely take over the signal and make some mesmerizing patterns. They are an extreme and immediate set of effects, perfect for the most intense parts of a live visual performance. A bonus feature of these buttons is that when subtle artefacts build up on the screen after a while even when the effects are all off, a quick press of one of these buttons and they are all cleared! No need for a reset mid performance!

Another effect unique to this device in the horizontal warp effect that makes the clean HDMI signal degrade into something that looks like a weak analog transmission.

8 knobs control the colour digitise effect and another 9 knobs control the "fragment" effect section that splits the image up and repeats it in slices at a 45 degree angle. These two banks of knobs can be linked together with a toggle switch for even more effect possibilities.

This unit also features a VGA input and can scale the signal to a HDMI output, all of the effects work the same when doing so."

Erica Synths Syntrx II Review and Demo // Not just for Bleeps, Fizzes and Ambient Soundscapes

video upload by Starsky Carr

"The Erica Synths Syntrx II is one of the most talked-about synthesizers of recent years — but three years on from its release, is it still worth your money? In this in-depth review and demo, I finally get hands-on with this modern spiritual successor to the legendary EMS VCS3 and EMS Synthi, and I want to bust two big myths: it's NOT as complicated as it looks, and it's NOT just a crazy sci-fi sound effects machine.
🎹 What's covered in this video:

-Syntrx II vs the original EMS VCS3 / EMS Synthi — key similarities and differences
-Syntrx II vs Syntrx I — what changed and why
-The 16x16 digital pin matrix explained simply
-Using the Syntrx II as a standard 3-oscillator monosynth
-The trapezoid (looping) envelope in practice
-All-analog signal path walkthrough
-Onboard 3-channel sequencer, DSP reverb and delay, envelope follower
FM, self-oscillation, noise modulation, and filter techniques
-Sample & hold circuit — how to set it up
-The joystick as an LFO / recording modulation source
-MIDI setup tips (offset fix, CC assignments for X and Y axes)
-Patch saving — what it DOES and DOESN'T save, and why it matters
-Honest pros and cons

🎵 Extended drone demo — 5 minutes of the Syntrx II running a single live patch with the trapezoid looping envelope, FM, noise, filter modulation via joystick, and DSP effects. The full version was over 10 minutes — it really is that good.

💷 Price context: Original EMS Synthis now sell for £24,000+. The Syntrx II comes in under £2,000. If you've ever wanted that Synthi sound without selling a kidney, this might be your answer."

"A good friend has left their Roland System 100 model 101 keyboard/synth + model 104 sequencer with me for a few weeks. I was curious to try it with the DinSync TR808 which is sending trigger to the 104 sequencer while I play random chords on the Prophet 10. A quick improvisation."

Sounds from Superbooth 2026: Ferry Island Modular

video upload by Perfect Circuit

Ferry Island Modular at Perfect Circuit

"Undertow from Ferry Island Modular is a two-dimensional wavetable VCO/LFO matrix for complex, spatial modulation, providing a powerful central nervous system for any modular system. With a 5 x 3 CV matrix, instead of a single VCO/LFO waveform, you get fifteen simultaneous outputs, each a unique position between two wavetable oscillators. Morph waveform and frequency across the horizontal axis with the mod generator across the vertical axis, taking you from clean to chaotic. No longer do you need to patch together disparate modulation sources in the hopes they can work together, the Undertow makes that a reality with so little effort it feels like cheating. Only for a moment though, as you start to unpeel the sonic onion of your modular system's potential with the Ferry Island Undertow as your sharpened steel.


Undertow Features

Morphing modulation matrix
15 bipolar CV outputs with LEDs
Two wavetable LFOs with wave, frequency, and bank control morphing along the X axis
Mod generator with selectable type shapes the Y axis from clean to turbulent
Clock inputs control left and right LFO frequency
EOC outputs
CV control with attenuation on wave and frequency
5 wavetable banks, more via firmware updates"

FLOW 3 | Auto-Dynamic Filter | Quick Overview

"Flow 3 is a filter that sounds bigger than it looks. Behind the compact 6 HP front panel lies a novel variation on the classic state-variable filter topology, offering simultaneous lowpass, bandpass and highpass outputs.

But the ace up Flow 3’s sleeve is its auto-dynamic nature: it is a filter that can modulate itself. This is achieved by a combined decay generator/envelope follower circuit which controls the filter frequency over an adjustable range."

Flow 3 is a filter that sounds bigger than it looks. Behind the compact 6 HP front panel lies a novel variation on the classic state variable filter topology, offering simultaneous lowpass, bandpass and highpass outputs. Core integrator saturation provides for a sound that’s clean, yet distinctive.

The resonance response is exceptionally smooth—and it can easily reach self-oscillation. In this mode, temperature-compensation and exact calibration make Flow 3 a reliable quadrature sine/cosine oscillator with tight pitch tracking.

But the ace up Flow 3’s sleeve is its auto-dynamic nature: it is a filter that can modulate itself. This is achieved by a combined decay generator/envelope follower circuit which controls the filter frequency over an adjustable range. Either fire decay envelopes from external triggers, or flip it to auto mode to follow along with the incoming signal’s amplitude envelope (or both, simultaneously).

via Perfect Circuit

The Arplus module from Zlosynth Instruments is a robust Karplus-Strong 6-voice resonator that gives you a bevy of musical scales at your fingertips. The Arplus works by selecting a particular chord based on the scale you select, stepping through the notes of that chord via the Trigger input and button. Use the Tone control to set the root note, and use the Chord control to select the particular chord. Both controls have corresponding CV inputs that let you create intricate sequences or melodic randomness. Choose from 31 different types of scales that include Western, Arabic, Indian, Japanese, and even quarter tones.

Internally, a burst of noise gets generated to create the sound, however, if you want more control over your noise bursts, an external input is available for you to patch in whatever you'd like. Use the String control to adjust how many virtual strings remain resonant after the trigger—up to 6 strings can resonate at a time allowing for soaring expanses of ambience and gorgeous clusters of notes. Sculpt the sound right on the module with a built-in filter, including resonance and cutoff, along with a Contour control that moves from short percussive bursts to long swells of washed texture.

Of course, no resonator would be complete without a stereo output, and the Arplus doesn't disappoint. Choose from three different stereo spreads: Ping Pong, which alternates voices between left and right, Root, which sends the Root to the Left and everything else to the Right, and Haas, which creates a stereo spread using the psychoacoustic Haas effect. The Arplus from Zlosynth is more than just your typical resonator, with an easy-to-read scale selector and a lovely sound that's sure to win over your heart and ears.

ARPLUS FEATURES

6 Voice Karplus-Strong resonator
External audio input for custom excitation sources
31 Different scales
Customizable chords up to 8 notes
CV-Controllable arpeggiator patterns
Quantized 1V/Out output
3 Stereo output modes

The Crow Hill Company Introduces the THE SH*T SYNTH

The Sh*t Synth - Walkthrough video upload by CROW HILL XTRAS

Press release follows:


The Crow Hill Company turns to extensive and rare collection to turn out THE SH*T SYNTH as compendium of 48 circuit-, wave- and sample-bent instruments

EDINBURGH, UK: The Crow Hill Company is proud to turn to its own extensive and rare collection of hardware to turn out THE SH*T SYNTH — available as a compendium of 48 circuit-, wave- and sample-bent instruments inspired by some of the Edinburgh-based enterprise’s eclectic musical favourites (spanning the likes of Aphex Twin, Boards Of Canada, Joe Maus, Jon Brion, Laurie Spiegel, Radiohead, Throbbing Gristle, and Yazoo) to create something that they collectively ask: is it just shit or ‘the shit’? — as of April 7…

Whatever way anyone chooses to read into the titling of THE SH*T SYNTH as the latest entry into The Crow Hill’s ongoing ORIGINS series of sample-based virtual instrument plug-ins, one thing is for sure: it readily represents a broad selection of three categories of 16 workhorse instruments each, effectively wrapped up into a single plug-in designed to bring a cohesive approach to making music more edgy, lo-fi, retro, and — swimming against the technological tide of so-called progress — decidedly AI (Artificial Intelligence) slop-free. From pianos to strings, plucks, beeps, bass, and pads, the compendium that is THE SH*T SYNTH has been lovingly sculpted by the Edinburgh-based enterprise’s media composer and ‘samplist-in-residence’ Christian Henson to take the hassle out of making existing sounds less refined, catering to those looking for an entirely new bank of Mellotron-style sounds as well as synths that have been long forgotten — for good reason, too!

Compression & Dynamics Patching on Eurorack Modular Synths // Sump Pump by Robots Are Red

video upload by DivKid

"Here we have SUMP PUMP from Robots Are Red (with circuit design from Setonix Synth). It's a 6HP stereo Eurorack noise gate that can also invert its behaviour into a compressor and with the 'floor' control it can also be an expander. We've 3 umbrella sections in the video with compression, noise gate and sidechain ducking techniques. Check out the patches and let us know which is your favourite. There's also an exclusive run down of the dirty bass patch on / divkid"

19:34 Creatively duck ambient FX - I love this mixing/production trick

It's a noise gate, it's a noise suppressor, it's a compressor, it's an expander, it's stereo.

The Specs and Stats:

Width: 6hp
- Attack and Release knob for envelope(s)

- Threshold for suppression/compression (0V - ~8V)

- Floor controls the amount of suppression/compression from -100dB to Unity and even up to +10dB for expanding the louds louder or make the quiets a bit louder.

- Level controls your overall output level

- Gate/Comp switch: When in "Gate" mode, whenever the input falls BELOW the threshold level, the envelope will engage towards the floor setting. When in "Comp" mode, the envelope will trigger when the input rises ABOVE the threshold setting.

-Stereo inputs and outputs. The envelope follower is assigned to the Left input, so the L input can also be used as a sidechain input for a mono signal (into In-R).

- Engage input. This is a gate input for manually engaging the envelope.

- Threshold CV input. This offsets from your knob position.

- Floor CV input. This also offsets from your knob position.

- Duck CV Input. This is an envelope follower input that applies and inverted envelope to the level of the signal. Send a simple pulse or trigger, an actual kick, an envelope, or anything else into this to duck your signal.

-Envelope Output. The envelope Output does not follow the "floor" settings and always outputs a full voltage envelope.

Special thanks to SetonixSynth and many others for really helping make this module a reality.

Also check with your favorite dealers on the right for various deals and bundles.

"Akai's MPC Sample is a portable chopping machine that is ready to go whenever a moment of inspiration strikes or as your lightweight companion through a day of slow-moving errands. Styled after their beloved MPC60, this beige beauty gives nostalgia and function in a battery-powered package. To ensure the size and ease-of-use remains paramount, the MPC Sample has a stripped down OS and micro pads but don't let the size fool you: this is an MPC through-and-through.

Whether using the built-in microphone, the stereo 1/4" jacks, or USB audio, you get quick access to the Sample Record section that is as easy as pressing a pad. A few quick trims using the multifunction knobs or using the shift and main encoder in combination will have you chopping and trimming in no time. Once you have your samples loaded, chopped, and assigned, recording a sequence is just as easy: just set the mode to Seq, adjust settings to taste, press the pad you want to record to, and you've got a loop. Resample that loop for further processing, use the step edit mode to make micro adjustments, and precompose a few sequences to switch between for full track performances.

The MPC Sample lets you engage effects in two different ways: the Knob FX and Pad FX. As their names portend, the Knob FX gives you access to a gang of effects including delays and reverbs, amp simulations, modulation effects, and vintage emulators. These effects are controlled with the three multifunction knobs for excellent playability. The Pad FX, on the other hand, are 16 always available effects that get triggered momentarily by the pads and are expressed via velocity. This is where you can get a stutter effect, several coloration effects, a half-speed effect, and other performable, musical delights. A fantastic choice for newcomers and veterans alike, the MPC Sample from Akai is a powerful tool for studio or stage that complements just about any other piece of equipment in your audio arsenal.

KONSTRUKT-8 is an expressive live performance instrument and sound design tool – plus a hands-on deep dive into electronic circuit design. Each of its eight DIY modules comes with a detailed build guide and can be explored on a breadboard first, letting you trace every circuit design decision before assembling the final instrument.

KONSTRUKT-8 includes four fully analog drum voices:

• Kick Drum. A resonant bridged-T network produces deep, punchy kicks.

• Snare Drum. A burst of filtered transistor noise layered over a tuned resonator creates a crisp snap.

• Hi-Hat. Six dissonant square-wave oscillators are mixed, filtered, and overdriven to create metallic percussion.

• FM Drum. Two interacting oscillators form a versatile percussion voice capable of kicks, toms, bells, and cymbal-like sounds.

A four-channel drum sequencer lets you tap in rhythms that loop automatically. Under the hood, shift registers store the pattern as a circular sequence of binary data.

All voices feed into a four-channel mixer with per-channel FX sends and a master insert, allowing you to shape the entire beat with external effects or the built-in distortion and compressor.

Two effects modules complete the system: an analog bucket-brigade delay (BBD) with flanger and delay modes, plus a diode-based compressor with sidechain capability.

WHAT’S INCLUDED

Both versions ship with:

• EDU DIY Kick Drum kit

• EDU DIY Snare Drum kit

• EDU DIY Hi-Hat kit

• EDU DIY FM Drum kit

• EDU DIY Drum Sequencer kit

ULTRAMASTER KR-106 Open Source Roland Juno-106 Soft Synth Emulation

"A virtual analog synthesizer inspired by the classic Roland Juno polysynths, with DSP calibrated from hardware measurements, firmware analysis, and factory schematics. 6-voice polyphonic.
Free and open source. AU, VST3, CLAP, LV2, and standalone."

Additional details via Reddit:

"We started building a Juno software synth in a Brooklyn loft in 2000. 25 years later, we're releasing it as open source. Meet the Ultramaster KR-106.

Back in 2000, my buddy Dave and I started Ultramaster Group with a wild idea: professional audio software for Linux. We were young, broke, working in a loft in Brooklyn, and perhaps a little bit ahead of our time.

Life happened. I went on to start a screen printing studio. Dave ended up at Google. But we never really stopped thinking about the synth.

Fast forward 25 years. Hardware is exponentially faster, DSP methodology has evolved, and we now have access to oscilloscopes, service manuals, and communities like this one. So we went back to the source code and overhauled everything.

The KR-106 is a 6-voice polyphonic Juno-106 emulation with:

Per-voice DCO, VCF (TPT cascade, IR3109 OTA-C design with 2x oversampling), VCA, and ADSR
Sub-oscillator (CD4013 flip-flop model) and noise source (2SC945 avalanche model)
PWM modes (manual / LFO / envelope)
4-position HPF (bass boost / flat / 240 Hz / 720 Hz)
Per-voice component variance modeling analog tolerances (pitch ±3¢, envelope ±8%, VCA ±0.5 dB, pulse width)
BBD chorus emulation (MN3009 modeled with Hermite interpolation)
Arpeggiator, portamento, Mono/Poly I/Poly II key modes
Two calibration modes: '1984 Mode' (firmware + schematics) and '1982 Mode' (circuit analysis + hardware measurements from my own Juno-6)
128 factory presets decoded from original SYSEX data
AU/VST3 on Mac, VST3/LV2 on Linux, VST3 on Windows, plus Standalone
It's 100% free, GPL-licensed, and we don't take donations. We just want it to be as accurate as possible, and we'd love help getting there.
