"The 223 Location Voltage Processor is intended to be used with the 227 System Interface Module in a quad setup. It contains four separate voltage controlled processors that output an X and a Y voltage for the 227 assign inputs.
The top row of knobs defines the operating range by adjusting the baseline of operation. The Balance adjusts the left to right panning. The Cross-Pan controls row modifies both the X and Y outputs and the exact function changes with the setting of the Balance control. These controls are described in more detail under Operations below."

"The Korg Electribe ER-1 has 4 voltage-controlled oscillators — the exact number needed for a 4-voice fugue. So I wrote one. Because it seemed like one of the dumbest things I could do with a drum machine.
This is a Prelude and Fugue for the ER-1, performed live with piano accompaniment on an early 1900s Krakauer Bros. grand piano.
"This patch is built around the A-128 Fixed Filter Bank, one of our classic designs. The filter bank is pinged by a short burst of noise shaped by the new A-142-5(1U) Dual Decay/LFO. Sometimes this module also receives a gate at the Voltage Controlled Loop input, which creates ratcheting-like sounds. The noise also runs through a bandpass filter, with the cutoff being modulated.
To get these sounds on the Fixed Filter Bank, feedback is essential. The short-noise input goes into a mixer, then from the mixer to the filter bank. The output of the filter bank goes into a multiplier; one path goes to the camera, while the other is amplified with the A-119-2 and returned to the mixer with inverted phase.
And the whole thing is split and also runs through a BBD, which is why it has a bit of noise."

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.

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).

NINA Macro Oscillator Mode - BRAIDS Update! Demo and deep dive with THE UNPERSON video upload by Melbourne Instruments
"The powerful new Macro Oscillator Mode firmware update for Melbourne Instruments' motorised polysynth, NINA, has arrived. This new update adds 45 synthesis waveform models using open-source code from Émilie Gillet’s Mutable Instruments Braids, one of the most celebrated Eurorack synth modules.
This new mode massively expands Nina's sonic capabilities, unlocking a new world of synthesis, from classic analog textures to cutting-edge digital experimentation. Powered by Nina’s innovative architecture, the new Macro Oscillator Mode delivers an incredibly versatile hands-on sound design experience unlike any other.
In this video Melbourne Instruments collaborator THE UNPERSON takes a deep dive into Macro Mode, exploring some of the Macro Oscillator models, and demonstrates just some of the 60 new presets created for this update, exploring the sonic possibilities of the new Macro Oscillator.

Press release follows:
Melbourne Instruments brings Braids engine to desktop NINA analogue polysynth
“NINA has always been an absolute powerhouse of a synth, but this update is insane; OSC 3 gives you 45 Braids macros across 12 voices, plus its massive mod matrix — the range of sounds and textures you can create now knows no bounds.”
- Musician/sound designer PROTOVOLT, 2026
MELBOURNE, VIC, AUSTRALIA: Melbourne Instruments is proud to bring Mutable Instruments’ Braids engine — Emilie Gillet’s celebrated open-source macro oscillator — to its desktop NINA analogue polysynth, as of April 30…
Available as a free firmware update, all 45 Braids synthesis models run across NINA’s 12 true polyphonic voices, each shaped by a dedicated overdrive-able analogue filter. Ultimately, users can now layer Braids and analogue VCOs (Voltage Controlled Oscillators) across four multitimbral parts, morph between presets, and sequence everything.
Duly described by Mutable Instruments as a macro oscillator, Braids was a mono Eurorack module: one voice, no internal filter, and no modulation routing. It is now something else entirely on NINA, itself described as the world’s first motorised polysynth. Put it this way: when switching layers, the motorised knobs snap to new positions; morph between patches and they sweep in real time. Meanwhile, modulation routings are all visible on the panel from the moment they are selected. Surely Braids has never been this hands-on.
Digging deeper, each waveform model is shaped by two expressive parameters — Timbre and Color — adapted from the original Braids module. More meaningfully, these controls affect multiple tonal dimensions simultaneously, producing complex, evolving, and musically responsive sounds. Spanning analogue VCO emulation, vowel and formant synthesis, 2-operator FM, physical modelling of strings and wind instruments, wavetable synthesis with smooth interpolation, granular synthesis, and electronic drum simulation, the 45 models evidently elevate NINA to a new level, further cementing itself as a premium analogue polysynth powerhouse for experimental, generative, analogue, and digital synthesis.
Says musician/sound designer James Terris, ending on a high note: “I’ve always described NINA as a beautiful beast — analogue oscillators paired with its super-fat and driven analogue filter make it beastly! But while the existing wavetable oscillator adds a crystal sheen that provides a beauty, the new macro oscillator models expand this tremendously. Indeed, it can go from delicate FM, Karplus-Strong, and even vocal formant textures straight into swarming, stacked super-waves. With this update, it feels like an instant NINA ‘MK-2’!”
Excluding taxes applicable to the territory concerned, NINA is presently priced at $3,299.00 USD in North America; €3,165.00 EUR in the EU; £2,835.00 GBP in the UK; and $3,499.00 USD in Japan, while it is presently priced in Australia at $4,995.00 AU, including GST (Goods and Services Tax) — all via Melbourne Instruments’ growing global network of dealers.
Coinciding with the new NINA MACRO OSC UPDATE firmware release, owners of the world’s first motorised polysynth can also download 60 new presets for free from here: https://www.melbourneinstruments.com/presets#nina
"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.

The system generates cross-modulated frequencies and evolving textures, blending harmonic warmth with harsh dissonance. Push the controls far enough, and the gate opens, unleashing intense, unstable sonic states.
Features:
* FM-based drone engine with deep modulation * Emotional state switching: Pain / Happy / Anger / Love * Joystick controller for expressive performance * Light sensor for reactive sound modulation * Full CV control (Eurorack compatible) * Works as both standalone instrument and modular system component * Integrates with sequencers, LFOs, and external CV sources
This isn’t just a synthesizer—it’s a performance instrument for emotional exploration, where tension and harmony continuously collide.
"In this in-depth demo and review, we explore the GS MUSIC Bree 6 keyboard — a 6-voice VCO-based analog synthesizer with a fully analog signal path, built-in chorus, delay, arpeggiator, and sequencer. If you love that vintage-meets-modern sound, this one might surprise you.
From raw oscillator tones to lush stereo pads and punchy basses, I break down what makes this synth special — including its unique double/triple arpeggiator modes, MPE compatibility, and rich, characterful sound that sits somewhere between classic Roland-style synths and something entirely new.
If you’re into synths like the Roland Jupiter-8 or Roland Juno-106, this is one you’ll want to hear.
🔍 What’s Covered Sound demo (full track made entirely on the Bree 6) Oscillator section: saw, pulse, sub oscillator 24dB analog low-pass filter with resonance & key tracking Dual ADSR envelopes & fast modulation Voice modes: poly, mono, unison & stereo spread Built-in chorus & analog-style delay Unique arpeggiator (double & triple note modes) Sequencer workflow & performance features MPE support & expressive control
🎛️ This isn’t just another vintage clone. The Bree 6 blends:
Raw VCO tone with modern reliability Hands-on workflow (minimal menu diving) A distinct character that feels alive and immediate A surprising amount of depth for a single-oscillator synth 🎧 Who Is This For? Analog synth lovers Producers looking for fat, mix-ready tones Fans of classic Roland-style sound with modern features Anyone wanting a hands-on, inspiring instrument"
We’re proud to present the Bree6 Keyboard, our first synthesizer with an integrated keyboard, designed and produced in Argentina for the world. 💙
Built on a six-voice analog architecture, it delivers a powerful and expressive sound engine capable of everything from solid basses and leads to rich, evolving pads. Now expanded with a built-in sequencer and advanced arpeggiator, it becomes a complete performance and composition tool.
With its one-knob-per-function interface, semi-weighted keybed with velocity and aftertouch, and fully analog signal path, the Bree6 Keyboard is designed for immediate, hands-on control—no menu diving. Immediate Control. No Menu Diving.
The Bree6 Keyboard version is designed to deliver an immediate and intuitive hands-on experience, eliminating the need for deep menu navigation. Its interface follows a one-knob-per-function philosophy, providing direct access to all key parameters for fast and precise sound shaping.
"For the uninitiated, the Lambda is a fully polyphonic keyboard, brass and string synthesizer with two sections: Percussive (Pianos, Harmonics and Clav) and Ensemble (Brass, Organ Chorus and Strings). The sounds from these sections can be used in any combination and output together in mono or stereo.
The chorus phase effect is rich and sounds great when using the Lambda in stereo. The effect can be set to either or both the Percussive and Ensemble sections and its speed can be controlled with the joy stick. A pair of tuning controls allow you establish the range of the chorus phase, from minimal to lush to seasick.
Everything on the Lambda works as it should and sounds excellent. All the jacks work as well. The expression jack uses a control voltage pedal, not a standard expression pedal. I’ve used an Expressive Touché controller with this (set for 0–5 volts as required for the Lambda), and the keyboard responds with volume changes accordingly.
The sliders work fine, with no noise or stiffness. All the controls turn and function as they should."

This is the first post to feature the Beers Melakarta.
"Feeding the Beers DAC and Beers Melakarta several triggers from ALM Pamela’s New Workout, and then modulating the pitches of the two Metasonix RK7 VCOs and the CV on the Metasonix RK8 Filterwall. Gated reverb from the Alesis MIDIVERB II."
"The idea for this module came from my friend Rodrigo Kendrick. He was a bit burned out on western tonal structures, and had recently missed out on an electronic lehra machine in a facebook marketplace deal which fell through. These machines are a kind of practice tool for carnatic musicians that plays a wide variety of different raga. Think that 'casio auto-chord' function on old casio keyboards, but for carnatic music.
Unwilling to wait for another one to come up on the used market, he did some cursory research, and sent me an early-morning design document, expanding the functionality of DAC with a scheme of two rotary switches and one toggle switch to select the pitch sets for all 72 Melakarta ragas and specified a clock input that would run up and down the selected raga in ascending then descending order, with the ability to turn around or reset on command. In theory this would allow the complex rhythmic and sequence rules of the raga to be implemented with external logic and sequencers, but still give the module enough sequencing functionality to explore the pitch sets of these raga on it's own.
I got excited and went a bit silly 'helping' until we had shoehorned in a pile of other features like binary addressability of the selected swara (interval), gate outputs for each swara, an 'inhibit' input that mutes the transposition voltage while the clock continues in the background, CV controlled halving of the clock frequency, extra +1oct input, and the logic-inverting toggle switches from the DAC on several inputs.
This design is all analogue using discrete MOSFETs and 0.1% tolerance resistors in a weighted DAC driven by a 4000-series CMOS based sequencer.
Yes, it might have been simpler to use a microcontroller."
