This Tiny Synthesizer Runs On Pure Light | Solarix Demo

video upload by Sid Rockett

"Introducing Solarix a tiny, self-powered synthesizer featuring an integrated solar cell that runs completely on light. No batteries, no USB power, and no external power supply needed.

In this video, we test Solarix to see how ambient light and shadows dynamically alter its pitch, rhythm, and sonic textures. As light intensity changes, the circuit reacts in real time, turning photons into raw analog chirps, evolving drones, and rhythmic glitches.

Plexiphon Is Now Shipping! | Make Noise

video upload by MAKEN0ISE

"On Saturday, October 3rd, at 3 pm, Tom Erbe will be at Perfect Circuit in Burbank, California, talking about all things Plexiphon and soundhack. The event is free!

The Make Noise Soundhack Plexiphon is a stereo, modeless spatial texturizer which allows for continuously morphing between reverberations and multi-tap echoes, the widest range of possible results being neither reverb nor echo, and all results highlighting and amplifying character previously hidden in the source material being processed.

The Plexus control simultaneously modulates the number of feedback paths in the algorithm, and their entanglement together. The Size of the paths determines the temporal relation between them, operating like a 'delay time,' or a 'room size,' at either extreme of Plexus.

Diffuse and Color offer softening/sharpening/darkening/brightening effects over time.

Couple and Skew are stereo operations: Couple determines to what degree the left and right sides are isolated or intermingled (from 'dual mono' to fully interlaced stereo), while Skew offers simultaneous inverse or tandem control of the left and right paths on the Plexus, Size, and Color parameters.

The Send gate input (normalled high, or patchable) determines whether and when the input signal will be fed into the Plexus.

An envelope follower is provided at the CV output for re-integration of the Plexus into its own controls or elsewhere in the voltage controlled system.

Plexiphon is built from entirely new code by Tom Erbe, specifically for Make Noise’s newest digital hardware.

ZEROBOY: a Zero-input mixer demo. This time with a beat!

video upload by manmade madman

"Sometimes, you just have to have a play!

Available now at store.denversynth.com"

ZEROBOY

Zero-input mixer. DIY noise artist's playground.
A digital no-input mixer: four channels, two effect returns that are full mixer channels in their own right, db-cell running as the board's own noise floor, and a live patch bay — everything you hear starts as the board's own hiss going round a feedback loop until it finds a mode. CASCADE feeds each channel into the next, wrapping channel four back to channel one; CHEAP/SOLID decides how hard the shared power rail sags and lets every channel modulate every other one through it.

ZEROBOY plugin GUI
Four mixer channels, each with seven selectable circuit topologies and Mackie-style 3-band EQ, plus a CASCADE that feeds straight into the next channel — channel four wraps back to channel one

Reverb and delay aren't send effects — they're two more full mixer channels with their own gain, EQ, and aux sends, already wired into a two-node feedback loop with each other

"Your ears lust for the sacred and the profane; Asura, our first standalone synthesizer, satisfies the desire for both.

In Indian and other Asian mythologies, Asuras are depicted as celestial beings of immense power; sometimes benevolent, sometimes evil, and in opposition to the Gods.

Our synth distills these values into its sonic soma. It models itself after no known synth, and does not wish to. With a six-voice polyphonic wavetable architecture, an inbuilt delay and a signature Animal Factory analog fuzz circuit, it creates soundscapes that range from ethereal lushness to visceral devastation.

How serious is it? With a multitouch pressure sensitive keyboard, bidirectional USB MIDI, compact form factor, web editor and a comprehensive modulation matrix, this might just replace your current polysynth.

The Hope - Circuit3 & Vince Clarke

video upload by Circuit 3

Update: you can find an interview with Circuit3 and the collaboration on ELECTRICITYCLUB.CO.UK here.

"With grateful thanks to artist Jackie Hudson Lalor for the production of this video and Kat Lalor for assistance with post-production.

The Hope is taken from the album 'Metanoia: Music From Therapy' available on CD & Vinyl from circuit3.bandcamp.com, available in Digital from mortalitytables.bandcamp.com

Circuit3, the retro-futurist project of Dublin-based Peter Fitzpatrick, steps away from his melodic synthpop background on Metanoia. The album moves into spacious, quietly expressive instrumentals. The sound is minimal and tactile, shaped by the classic late70s and early80s electronic vocabulary without being locked inside it.

Metanoia grew out of therapy and the slow process of letting difficult truths surface. Instead of singing those words, Fitzpatrick shaped them through analogue machines. The title refers to the deep shift that can follow self-reflection: a break, a reset, a way of living with more honesty.

A defining moment in the project was the opportunity to work with Vince Clarke, a longstanding influence on Fitzpatrick’s music. They created an eleven-minute piece titled ‘The Hope’, named after the bar near Farringdon, London where that first conversation between Fitzpatrick and Smith happened. The collaboration feels like a dialogue across time: the artist Fitzpatrick once was, the one he is now, and the one emerging through this process.

The album closes with ‘The Hope’. Across eleven minutes, it builds a melodic drone landscape that holds both hopelessness and hope at the same time. The piece suggests that neither feeling disappears; they sit beside each other, always present, always waiting to be recognised."

VAV N-Wave: Middle-Out Waveshaper

video upload by Magical Synth Adventure

"Join me as I take the @control_voltage VAV N-Wave Middle-Out Waveshaper for a spin!

The N-Wave is a really imaginative waveshaper. Some waveshapers might fold over the peaks of an incoming waveform, some might rectify them - squaring things off like a fuzz pedal. N-wave keeps the peaks of waveform - like the top and bottom of a saw wave - intact, and instead lets you shape and turn up on the volume on a section in the middle of the waveform - leading to unique tones. This is especially true, as you can vary the width of this middle section!"

video uploads by control_voltage

Playlist:

1. VAV N-Wave: Step Sequenced Threshold

One fun live performance (or studio) use for the N-Wave is to connect a Step Sequencer on the Threshold CV and generate different timbres for each step in a sequence. These act as accents and add a lot of life and feel to your sequences and the feel can easily be changed on the fly using something like a Joranalogue Step 8 as your source of steps.

2. VAV N-Wave: Threshold Ring Modulation

In Part 2 of the VAV N-Wave Video Manual, we look at using the threshold control and bipolar vca cv to create new waveforms that have a mixture of normal and ring modulated (quadrature) segments.

3. VAV N-Wave Mangles a Triangle

Here, the N-Wave does quite a number on an unsuspecting triangle wave with the help of some nearby modules. N-Wave is kind of like that one kid's house where everyone hung out and cooked up weird DnD campaigns or something. But for modular signals.

"N-Wave is a novel waveshaper for the Eurorack modular format. Unlike traditional wavefolders and clippers, which operate on the peaks of a waveform, N-Wave leaves peaks intact. All you need to expand your sound palette greatly is a VCO signal and a few twists of the knobs!

Using its internal bipolar VCA (aka four quadrant multiplier, aaka ring modulator) you can apply gain reduction and polarity inversion to an inner portion of the wave slope that you define with the THRESHOLD and OFFSET controls.

All functions can also be controlled via control voltage inputs. LFOs, Audio Rate VCOs, ADSR Envelopes, 1V/Oct signals, sequenced voltages, sample and hold signals, noise, and sub octave signals are all very good choices and can produce results ranging from very musical to very strange. An external detector signal can also be applied if you don't want to trigger the detector on the waveform you're modifying.

If you like, you can also use N-Wave as a high quality bipolar VCA, attenuverter, or ring modulator with the THRESHOLD set to maximum and dynamically mute the effect by applying 0V or a negative voltage to the threshold either using a sequencer or manual control, which allows for hocketing and rhythmic effects.

N-Wave can also operate all the way down to 0hz (DC), so, in addition to audio, it can process LFOs, envelopes, 1V/octave sequences, and any other signal that varies amplitude over time (Sorry, square waves and pulse waves. Your super-sonic rise times are hard to shape in an audible way, but you do work well as control signals).

N-Wave is 10HP and uses Burr Brown op amps for the primary signal path alongside high quality Texas Instruments ICs that are carefully chosen to best fit their roles in the circuit."

"Oberheim Service Notes from 1980's in Oberheim 3 Ring Binder
These documents comprise an official Oberheim issued compilation of Authorized Service Notes.

These are NOT Oberheim Technical Service Manuals.

They are Engineering Change Orders (ECO's) which are mostly circuit updates.

Each ECO has been implemented over time to improve the performance of a particular Oberheim Model.

They have been grouped to include all the changes to a particular model.

The OB-Xa Bulletins for example are grouped into the 100 series; The Expander is the 600 Series.

One would still refer to the actual Oberheim Service Manuals to actually perform these updates.

View this binder as an Addendum to each of the Service Manual models on the list.

The Bulletins cover:

There are no OB-Sx Service Notes.

There may be a couple of Service Notes missing. Either they went missing or were never there.

I used to be an Authorized Oberheim Service Center, but Oberheim went out of business

and resurrected as ECC Oberheim, then I believe went out a 2nd Time.

I lost on that deal - due to Unreimbursed Warranty Claims.

The package weighs over 6 LBS. which is charged as 7 LBS per USPS."

Introducing Thorus XT

1. Introducing Thorus XT - Video credits: Anthony H. | Music credits: Théo G.
2. UVI Thorus XT | Overview - Video credits: Venus Theory
3. UVI Thorus XT | Showcase - Video credits: Théo G.

"Thorus XT - Extended Chorus Designer
https://www.uvi.net/thorus-xt

Discover Thorus XT, a state-of-the-art chorus effect offering the best of both digital and analog circuit-modeled techniques with up to 8 variable, fully continuous voices, and deeply shapable extended analog controls.

Also included in SonicPass ➡️ https://www.uvi.net/sonicpass"

A deep, flexible, state-of-the-art digital chorus, Thorus has long been one of UVI's best-selling effects. Thorus XT offers a brand new take, driven by advanced DSP and joined by a second engine that faithfully models the analog bucket-brigade circuits that chorus was born on. Two worlds, one plugin, from brilliant shimmer to grainy vintage modulation, and everywhere in-between.

Your Sound, Your Way

Both digital and analog engines run on the same morphable 8-voice architecture and the same set of controls. Set your modulation once, switch engines, and hear the identical movement through two very different paths, keep whichever one best suits the material.

Two Engines, Unified Control

Cutting-edge DSP drives a variable chorus architecture with continuous and morphable voice control; sweeping voices results in the last voice fading in and out smoothly, with no stepping. Speed and Depth shape the modulation, Shape sets its waveform as sine or triangle, Edge dials feedback and color, and Stereo Mode places the image. Fewer voices give pronounced, identifiable modulation; more voices blur the line into a thick, immersive wash.

Digital - Clean, Precise, Transparent

The digital engine is the Thorus chorus you know and love, refined. Clean, precise, prized for its clarity, now with a continuously variable voice count. Every voice reads a single shared delay line at interpolated positions, for a crystalline, detailed sound. When clean isn't the objective, Quality becomes a band-limited sample-rate reducer delivering a downsampled, lo-fi edge that stays musical where it counts.

Analog - Warm, Colored, Alive

The analog engine is a faithful bucket-brigade chip emulation, found in classic hardware units like the Dimension D, and Juno-6. Where the digital engine is clean by design, Thorus XT’s analog engine gives you the natural imperfections of hardware: aliasing, resonance, pumping compression, hiss, per-voice variation—all fully shapable through an extended control set.

This Eurorack filter has AUTO DYNAMICS! // Flow 3 from Joranalogue *MEGA DEMO*

video upload by DivKid and Joranalogue Audio Design

"As we'd expect from Joranalogue, they take inspiration from classic, seemingly simple functions and turn them into musical and technically impressive devices. Flow 3 is a compact filter that builds upon on the idea of an auto wah, it's a filter with 'auto dynamics'. There's on board modulation, that can modulate itself or your modular system, stave variable filter outputs, CV over everything and an easy to play with layout in 6HP."

Update: Press release follows:

Joranalogue Audio Design announces availability of Flow 3 auto-dynamic filter module for Eurorack that sounds bigger than it looks

STEKENE, BELGIUM: having made its impressive-sounding debut during a showcase at SUPERBOOTH26, May 7-9, FEZ-Berlin, Germany, high-quality Eurorack music synthesiser modules-maker Joranalogue Audio Design is proud to announce availability of Flow 3 — an auto-dynamic filter that sounds bigger than it looks, thanks to the novel variation on the classic state variable filter topology that lies behind its compact 6 HP panel — as of August 25…

Firstly, Flow 3’s core integrator saturation of its simultaneous — low-pass (LP2), attenuates frequencies above the filter frequency (or cutoff) at -12 dB/octave and self-oscillates at a phase of 180°; bandpass (BP2), selects a band of frequencies around the filter frequency (but below and above that the attenuation slope is -6 dB) and self-oscillates at a phase of 90°; and high-pass (HP2), attenuates frequencies below the filter frequency at -12 dB/octave and self-oscillates at a phase of 0° — outputs provide for a sound that is clean yet distinctive.

RESONANCE response is exceptionally smooth — it, too, can easily reach self-oscillation (at higher feedback levels), the temperature compensation and exact calibration effectively transforming Flow 3 into a reliable quadrature sine/cosine VCO (Voltage-Controlled Oscillator) with tight pitch tracking.

The ace up Flow 3’s sleeve, however, lies in its auto-dynamic nature — helpfully highlighted by the non-erasable AUTO DYNAMIC FILTER graphic positioned across that compact, clean-cut 6 HP panel. After all, it is a filter that can modulate itself, achieved by a combined DECAY generator/envelope follower circuit controlling 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).

Saying all that, then, creating heavy-hitting analogue kick drum sounds becomes a breeze, but, with a bit of patching, Flow 3 can even be used as a spectrum splitter (or crossover), cleanly separating the full audio range into low and high portions, for dual-band signal processing — perfectly possible thanks to the Linkwitz-Riley filter response at minimum resonance.

Ultimately, users of Flow 3 can clearly get carried away as the Eurorack module concerned creatively takes the old auto-filter concept to new voltage-controlled heights, hearing for themselves exactly what the fuss was all about at that impressive-sounding SUPERBOOTH26 showcase!

Coming complete with a 16-to-10-pin Eurorack power cable, two black M3 x 6 mm hex screws, two black nylon washers, and a hex key, Flow 3 is available as a 6 HP module — measuring 128.5 mm (H) x 30 mm (W) x 52 mm (D) with a +12 V: 45 mA/-12 V: 45 mA maximum current draw, reverse polarity (MOSFET) power protection, 100 kΩ impedance inputs and 0 Ω (compensated) impedance outputs — through Joranalogue Audio Design’s growing global network of authorised dealers at a MSRP (Manufacturer’s Suggested Retail Price) of €215.00 EUR or $225.00 USD.
