"Messing about with noise and random voltages. This patch is just various noise sources through various filters, frequency-modulated by sample & hold, with envelopes controlling amplitude (VCA) or affecting filter frequency. No sequencer was harmed in the making of this video.
The @solidstatelogic BigSix is used to mix all 4 sounds, with the @vermonagear DSR-3 providing stereo spring reverb for the drone and occasional sound.
Video & performance by @DreamsOfWires
Patch Breakdown:
Drone: This is just pink noise going into the FIXED FILTER BANK 914, but with an LFO from the DUAL RVG modulating the mix between the left and right bands of the Filter Bank, creating that slow, breathing effect. The AJH SYNTH 914 has built-in, voltage-controllable mixing/cross-fading functionality, which wasn't present in the original Moog 914 on which it is closely based.
Percussion 1: White noise going to the SONIC XV Diode Ladder Filter, using its band pass output. One channel of the DUAL RVG is sending random voltages to the Sonic's Filter Frequency/Cutoff, whilst a DH-ADSR envelope generator controls its audio level in the TRIPLE CROSS (being used as a triple VCA).
Percussion 2: This starts with noise generated by the LUNAR MODULE - this has 2 noise sources with different character and tone control, and built-in distortion. Its output goes to the MATRIX VCF, which has 16 different filter modes, which I cycle through manually during the video. See out User Guide video for more information: • NEW MODULE! MATRIX VCF User Guide - Vintag...
Occasional Sound: Here I'm using the SAMPLE & HOLD module to randomly trigger the MULTI BURST ENVELOPS module. The Colour control on the Sample & Hold determines the range of random voltages generated. It is a combination of Low Pass and High Pass filter over the onboard noise that is used to derive the voltages, so turning it anti-clockwise from the centre acts as a low pass filter, reducing voltages produced to be in the lower range, whereas turning it clockwise of the centre position acts as a high pass filter, meaning voltages in the higher range. Since it is generating lower voltages here, it is only occasionally producing enough of a voltage change to trigger the Multi Burst Envelopes. If I raise the Colour control it will trigger more often.
The Multi Burst Envelopes produces a chosen number of bursts of the selected envelope shape. The built-in LFO controls the speed of the bursts, as does the Clock input, but both can be used together or independently. I'm using it to control the frequency of the ENTROPIC DOOM's low pass filter, to generate an occasional burst of filtered noise."
"I went to pull out my Korg ESX-1... and well... it's dead. Took it to a tech who also said it's dead. I'm going to try one more thing to see if I can get it working... we'll see. For now, I've thrown my Korg EMX-1 into the foray for drums since it can do mostly the same things. However, I forgot that the drum parts can't go through the filters. That's so dumb. What was Korg thinking? Makes no sense. Oh well. That's what I've got. I'd have actually expanded this track but couldn't because the next pattern in the EMX was something I didn't want to lose, so I just stuck to this one.
Elektron Analog Keys: Melody, Bass, etc
Korg EMX-1SD: Drums
NI RAUM: Reverb"
A desktop spring reverb unit featuring a built-in miniature spring.
You can use its high-quality, authentic spring to achieve a beautiful, classic reverb—or you can dive headfirst into the lush, vibrant resonance of a wildly oscillating spring, letting yourself drift and drown in its saturated wetness. It gets absolutely drenched.
And while nobody explicitly told you to shake it, smack it around, or slam it against the table... well, naturally, you’re going to do it. After all, there’s a real spring inside that actually shakes! It’s the thrill of the authentic.
Mix the clean-boosted signal (GAIN) with the spring-reverb-processed signal (REVERB), then adjust the overall output volume using the LEVEL control.
When the switch is in the down position, the signal bypasses the effect, passing directly from IN to OUT. The LED illuminates when the effect is active.
*Powered by a DC 9V power adapter (center-negative / Tip = -); sold separately.
Break your samples apart to build new and unique sounds
Play any audio file like a synthesizer-in tune with your song
Explore a new world of sound design with audio as your raw material
A firestorm of granular power
Grainferno is an advanced granular instrument built around a new way of synthesizing sound from existing audio. Its next-gen grain engine breaks your samples into microscopic fragments and rebuilds them into entirely new textures.
From pristine tonal clouds to experimental digital noise, Grainferno turns your sample library into an endless source of playable inspiration.
Make a synth from any sound
Grainferno can generate grains at speeds fast enough to cross into the audio range. At these rates, grains stop behaving like texture and start acting like oscillators-turning any audio file into a playable synth voice.
Even at audio rates, traces of the original sonic character remain, giving you unique synth building blocks with the spectral fingerprint of your source audio.
Add modulation and grain-level shaping to build ready-to-use granular synth tones that stay in tune with your song like a traditional synth.
"This update adds a compressor and a noise gate, making it possible to create a true gated‑reverb effect. Famous from the 80s productions, gated reverb is an audio processing technique that combines reverb with a noise gate to create punchy sounds while keeping the mix clean.
"First sounds with the Mannequins Sisters, such an interesting little module. In its core is a triple filter (Hi, Low and Band Pass) but it works great as an spectral mixer. I am slowly modulating the frequency cutoff so that the different sounds come and go progressively. Very little resonance added, it can be very resonant!

DEEP/4 is a painstaking recreation of one of the most powerful multi-effects processors ever built. Every algorithm has been rebuilt at the instruction level from the original 24-bit DSP hardware, preserving the exact digital character of the algorithms that made these units legendary in studios worldwide.
All 43 original algorithms, mathematically verified against the original DSP architecture. No guesswork.
Features
Four Independent Effects Engines
The DEEP/4 is a powerhouse multi-effects processor featuring 43 fully programmable, high-fidelity algorithms including reverbs, chorus, flanging, delays, distortion, and pitch shifting. Operate it as a single massive effects system, a pair of stereo processors, or four entirely independent units. Its advanced routing matrix supports true serial, parallel, and feedback configurations to sculpt complex effect topologies that conventional units simply can't touch. Flexible Multi-Unit Routing
Run all four units in series for massive effect chains, split them into parallel paths for layered textures, or use feedback routing to create evolving, self-modulating soundscapes. DEEP/4 provides independent routing control for each pair (A/B and C/D) plus a main bus link — supporting serial, parallel, and two feedback configurations with adjustable feedback amount. Use it as a single 4-unit processor, two independent stereo pairs, or four standalone effects. 43 Algorithms Across 7 Categories
From lush reverbs and complex multi-tap delays to pitch shifters, dynamics processors, and guitar amp simulations — every algorithm from the original hardware is here, rebuilt at the instruction level and fully programmable.
"VA-1000 is a 16-voice virtual-analog synth built for speed: JP-style Ultrasaw, deep unison, a 9-mode filter with audio-rate LP FM 12, expressive LFOs and three envelopes, plus chorus / delay / reverb with ducking, all on a clean one-page UI. Software Download (NO HARDWARE INCLUDED)"
OB-Xf is a continuation and modernization of the last open source version of OB-Xd by 2DaT and later discoDSP, bringing together several efforts going on in the audio space and combining them inside the Surge Synth Team infrastructure.
It is an amazing freely downloadable virtual synthesizer inspired by the venerable Oberheim OB-X.
The original Oberheim OB-X is one of the best analog poly-synths ever, used by Rush, Van Halen, Queen, Japan, Eurythmics, Ultravox, Tangerine Dream and many others.
It is a classic synthesizer with a timeless sound that continues to captivate musicians and producers alike. With its rich, full-bodied tones and expansive sound design capabilities, the OB-Xf is the perfect choice for those looking to add a vintage touch to their music.
The OB-Xf is a synthesizer that has been designed to recreate the sound and behavior of the Oberheim OB-X, OB-Xa and OB-8. However, the architecture of the original instruments was limited in some ways, so the OB-Xf includes a number of additional or altered features. Overall, the OB-Xf has been designed to produce a sound that is as good and as rich as the original OB-X.
Also, like many synths of the OB-X's generation, the OB-Xf has no internal effects so its sounds and textures can be greatly enhanced by the use of additional processing like chorus, reverb, delay, etc.
In this demo I will just let you hear what some amazing sound designers have made for this stunning synth simply by scrolling and playing some beautiful presets.
No additional effects or outboard processing here. What you listen is what you get!
YOUR NOVATION CIRCUIT TRACKS — REBORN AS A MODERN ACID MACHINE. FROM TIMELESS ACID HOUSE TO RAVE TECHNO
ACID transforms your Novation Circuit Tracks into a modern Acid machine, designed for genres such as Classic Acid, Acid House, Techno, Detroit Techno, Acid Techno, Hard Techno and Rave genres.
Roland TB-303 behaviour emulated — with a more modern sound, yet fully capable of delivering the classic tone. Modernised and expanded.
The pack includes 128 patches in total: 96 authentic 303-style Acid sounds plus 32 additional sounds, including a strong selection of polyphonic material such as chords and classic genre sounds to expand your productions beyond classic monophonic Acid lines.
All patches respond to velocity where appropriate, allowing expressive control and dynamic performances directly from the Circuit Tracks pads.
The 303-style patches are programmed to recreate the behaviour and response of the original machine — from timeless Acid House to harder Acid Techno and underground rave territories — featuring velocity-based accent behaviour, glide response, LFO modulation for evolving movement, and powerful modern distortion algorithms with delay and reverb send effects.
Completed with 64 drum samples (House, Techno, Hard Techno, 707, 808, 909 and more), ACID becomes a complete production toolkit — effectively turning Circuit Tracks into a purpose-built Acid production machine."
"Musical exploration of new eurorack filter by Crazy Chicken Modular - SHRIMPY."
Shrimpy is a fully analog multimode voltage-controlled filter with three simultaneous audio outputs: low-pass, band-pass, and high-pass. It was designed with a strong focus on character rather than neutrality.
The resonance is voiced to emphasize midrange frequencies, giving the filter a present, expressive tone that cuts through a mix. At higher settings, it becomes vivid and assertive without collapsing into thinness.
At the heart of Shrimpy lies an unusual distortion chain integrated directly into the filter core. This distortion adds a pleasant crunch, enriching the sound. When pushed further, it can turn glitchy and rustling, introducing rough textures and unstable edges that make the filter feel alive. It should be noted that the distortion sound characteristics will depend on the Shrimpy settings and the input signal, since distortion occurs in the filter core itself, rather than at its input or output.
All parameters are fully voltage-controllable:
Cutoff frequency (with and without attenuator)
Resonance
Distortion amount
This makes Shrimpy a flexible yet opinionated sound processing tool, well suited for experimental patches, aggressive basses, textured leads, drones, and evolving soundscapes."
"Here's a new track. I wanted to bring the Tempest back in and use it again... but almost everything about it is just difficult to use... I tried to sequence the beats, but the OS would freeze when doing it that way, so I had to opt to manually change beats. Using the external sequencer kind of ruins half the fun of the Tempest, so I chose to do it all in the box, and it's great for that... but it's extremely hard to put a track together using the Tempest.

Cirklon 2 sequencer
DSI Tempest (drums)
Moog Minimoog (bass)
Roland SH-101 (Bass)
Sequential OB-6 (arp)
Roland JD-990 (initial melodic pad)
Oberheim Matrix 1000 (later pad sound)
