Freshwater Announces Modern CPU Card for Fairlight CMI Series I, II & IIx

Press Release follows:

Freshwater announces the new FI50A Card

Freshwater writes a new chapter for the legendary Fairlight CMI

Today Freshwater announces a milestone event with the release of the FI50A card for existing Fairlight CMIs series I, II and IIx. We’ve spent over a year perfecting this project and now offer CMI users a unique opportunity to extend, preserve and enhance these remarkable and era-defining machines.

Installed in an original Fairlight CMI, the FI50A makes the instrument faster, more reliable and more convenient to operate whilst bringing the legendary CMI sound into the 21st century music production environment. We are currently focused on getting these cards into the hands of users and continuing to optimise the enhanced software bundled with them.

What is the FI50A?

The Freshwater FI50A is a complete modern replacement for the original CMI computer section, including CPU, graphics display, memory and library storage. It is compatible with Fairlight CMI Series I, II and IIx systems. The FI50A preserves the character, workflow and hardware experience of the original instrument while dramatically improving speed, reliability, storage and usability. It runs enhanced software derived from the original source code keeping the instrument recognisably and operationally a Fairlight CMI.

The card arrives pre-installed with a fully licensed original CMI sound library and adds practical modern ways to expand it, including enhanced 10-bit sampling, waveform upload over Wi-Fi, SD card and USB memory support. It also adds DisplayPort output, USB, Bluetooth and Wi-Fi while retaining support for legacy CMI keyboards, CRT/light pen operation, floppy disks, MIDI interfaces and Series I/II channel cards.

Installation is straightforward and fully reversible. Using the supplied user manual and online video guide, the original CPU and peripheral cards can be removed and preserved, the FI50A installed in their place, and the original peripherals reconnected.

For owners familiar with the CMI, the result is not a different instrument, but a transformed one: faster, easier to maintain and ready for contemporary studio use while remaining true to the original machine.

For more information, please follow the link below:

https://www.freshwaterinstruments.au/fi50a

“I once said ‘one day the whole CMI will fit on one chip’. We all had a laugh at that. Fast forward 40 years and that’s the reality. By making this new board compatible with the original CMI channel cards, the bits that make the CMI sound so unique are still there, while the digital part is a zillion times more powerful, smaller, cheaper and reliable.” —Peter Vogel

Plinky 12 Chords: Ramp Arpeggios

video upload by Making Sound Machines

"On our way to #Superbooth 2026! Really excited to see all our friends and fellow makers again!

This year, we will be showing the Plinky 12 family of expressive polyphonic touch synthesizers.

In this video, Enrica, engineer and musician of Düsseldorf-based synth maker Making Sound Machines, explores the new Plinky 12 Chords play surface.

The built-in sequencer produces a calm pulse, triggering an Arpeggio ramp at the beginning of each bar. With her left hand, Enrica selects which harmonies to arpeggiate from the rainbow chord palette at the bottom of the instrument.

With her right hand, she plays an expressive melody on the polyphonic play surface. The notes in this view are arranged in a tetrachord layout and adapt automatically to each harmony selected.

All sounds are produced with Plinky 12's internal synth engine."

Publison Infernal Machine + LinnDrum / Jam 1

video upload by Valmont

"Have you ever wondered if a Linndrum could sound... Not like a Linndrum?! Here's a first jam featuring a fully restored one for a client, along with a Publison Infernal Machine reissue, hand-built by my friend Valentin, aka “Vintage Standards” :)

LINNDRUM - This one came with a fun issue: the snare would trigger the side stick, and the toms would trigger the congas. Apart from various CMOS quirks of that kind, I rebuilt all sliders/faders (volume + pan), the trigger buttons and replaced the pots with custom clones made by my friend Manfred from VintageSynth&Co. I also swapped the audio caps for polypropylene ones and rebuilt the power supply. During the process, the CPU card failed so I had to debug the sequencer - turned out to be a bad address latch and a dead bus gate (no idea what caused that). All in all, a serious overhaul!

INFERNAL MACHINE - A very special device. The IM90 was originally designed by French engineer Philippe Petitdemange between 1983 and 1984, with development continuing until the final DSP update in 1989. Publison devices are infamous for their opacity: components were often stripped of references, making repairs impossible. No schematics were ever published or even formally documented, which made the Infernal Machine both exceptionally rare and subject to extreme prices (I’ve seen one listed around 20k€!!!)
Following Philippe’s assassination in 2019, much of the design knowledge risked being lost. Jonathan Prager was designated as the official Publison legacy/maintenance technician and undertook the task of redrawing schematics based on the original archives he bought to preserve these machines. Meanwhile, Valentin, a French expatriate living in Japan, independently carried out his own reverse-engineering and successfully built a true 1:1 clone. His version (named the Celestial Machine) fits the strictest definition of a clone: an exact replica running the original code, featuring a beautifully recreated remote controller and using NOS components throughout ; except for a new OLED display (co-designed with Bob Grieb of TaunTek).
This special Publison-badged unit was sent to me for testing and demonstration to original Publison co-founder D. Dean - more info soon maybe :)

By the way! If you’re curious, I wrote my master’s thesis on Publison, it was published in French (deal with it lmao) : https://www.ens-louis-lumiere.fr/wp-c..."

Patching Exciting Modulation for Filters // FIRST PATCH with Swell from Bartola Instruments

video upload by DivKid

"Here we have the new Swell Eurorack filter and valve gain stage from Bartola Instruments. We'll be exploring this in the usual in depth DivKid demo style in the future but wanted to share our literal first patch playing around with saturating, character oozing valve distortion and filtering ... and in doing so, share some modulation tips about how we like to patch modulation, mixing sources and making things feel exciting and dynamic. I hope the patch notes below are useful and let us know what you'd like to see more of with Swell."

"*PATCH NOTES*

The simple bit first - AUDIO PATH - two saw wave oscillators, changing the octaves between them at points, mixed into 'Swell' and then output into some stereo FX for background ambience.

The modulation is where this gets exciting going into the FM input (which modules filter cut off frequency) is my main envelope, a simple decay envelope. Resonance is modulated by a step sequence (external attenuation is the key here). Then the v/oct input is used as a place to input a mix of modulation. The first is an accent envelope, patching a less dense gate rhythm into a second envelope and patching that into a mixer. Then outputting the mixer into the v/oct input of the filter. The second is then the same step sequence as the resonance.

So with the mixer into the v/oct and the FM input I have 3 modulation sources modulating the filter frequency - main envelope, accent envelope & step sequence.

Modules used - Thonk Synth VCO, Joranalogue Cycle 5, TINRS Next Tuesday, Making Sound Machines Multiplikand, Bartola Instruments Swell, WMD + Infrasonic Audio Cosmis Debris, Vostok Instruments Fuji, Apollo View IOU, Thonk Synth dual VCA.

THIS VIDEO IS SPONSORED BY BARTOLA INSTRUMENTS* they have funded the creation of this first patch video and future demo video with Swell. Any questions just ask."

Plinky 12 Chords: 80s Brass

video upload by Making Sound Machines

"In this clip, Enrica from Making Sound Machines improvises on the Plinky 12 Chords play surface.

The internal sequencer advances through a progression of harmonies, playing and arpeggiating a new chord each bar. With her fingertips, Enrica improvises an expressive melody on the play surface.

The notes in this view are a stack of the chord notes for each of the harmonies from the rainbow chord palette at the bottom of the instrument. This allows Enrica to freely arpeggiate and transition from harmony to harmony, sometimes leading, sometimes trailing behind the chords launched from the sequence.

The polyphonic play surface reads both play position and pressure of the touch, allowing for an intuitive and nuanced play style. All sounds are produced with Plinky 12's internal synth engine."

Plinky 12 Chords and Model:Samples

video upload by Making Sound Machines

"In this video, Enrica and Roland from Making Sound Machines play a melodic techno track, performing live with the built-in polyphonic arpeggiator and the sound modulation in Plinky 12 Chords.

Plinky 12 receives a MIDI clock signal from the Elektron Model:Samples, synchronizing tempo and transport between both devices. Model:Samples is a fantastic all-digital drum machine and provides the beats you hear in this clip. All synth sounds are produced with Plinky 12's internal synth engine.

Plinky 12's sequencer advances through a harmonic progression, while Roland performs on the touch surface, editing the polyphonic arpeggio. As the track progresses, he taps the touch surface to add or delete notes in the arp pattern.

Enrica operates the model cycles, bringing in layers of drums, while Roland manipulates the XY pad on Plinky 12, modulating the synth and effects setting. This allows them to build and adjust the arrangement on the fly.

This track was composed for a live set at Club Synth, an event our friends Stijn and Priscilla from This is Not Rocket Science are hosting and organizing quarterly at Ruigoord near Amsterdam. Thank you for inviting us and putting in the hard work to create such a lovely event!"

Plinky 12 and Plinky v3

video upload by Making Sound Machines

"This video clip is a duet using a Plinky each from both generations: a Plinky 12 Chords providing glissandi and harmonies, and the original Plinky v3 from Thonk providing the main melody.

Enrica, engineer and musician of Düsseldorf-based synth maker Making Sound Machines, plays the original Plinky v3, with long melodic arcs and the characteristic melancholic sound at the touch of her fingertips.

Roland slides his fingertips along the rainbow coloured columns of Plinky 12 in Chordnotes view. The notes in this view are a stack of the chord notes for each of the harmonies from the chord palette at the bottom of the instrument.

This allows him to freely arpeggiate and transition from harmony to harmony. After the intro of the piece, Roland starts a harmonic sequence on Plinky 12 to accompany the notes Enrica plays on the original Plinky.

The lead synth in the beginning and throughout is captured directly from Plinky v3. All additional synth sounds and effects, the harp-like sound and glissandy in the accompaniment, are produced with Plinky 12's on-board synth engine.

Plinky 12 is a family of expressive polyphonic synthesizers. The three instruments are built around a shared polyphonic synth engine. Designed by mmalex, it evokes the unmistakable melancholic sounds of the original Plinky.

Each instrument is designed in collaboration with a different synth maker, lending each panel a distinct playability and unique character.

Plinky 12 Chords is a harmonic inspiration machine. It lets you improvise melodies and chords, with expressive control over voicings, progressions, and immediate musical play. Created by Making Sound Machines, Chords is the panel for finding beautiful harmonic movement quickly.

Plinky 12 Toadstep is a 4-track step sequencer built for super funky riffs, experimental self-generative melodies, and good ol' Acid. Created by Toadstool Tech, the designer behind the Ectocore Eurorack module, Toadstep is fun, immediate and easy to jam with!

Plinky 12 Blocks is an open panel built for experimentation, with monome-grid compatibility, Plinky style touch synthesis, and a browser-based coding environment just a click away. While it comes with a fully playable design out of the gate, creator mmalex invites you to build your own adventure with this panel. If you can imagine it, you can make it!"

In this video, Enrica and Roland from Making Sound Machines explore the three new Plinky 12 instruments: Blocks, Chords and Toadstep from left to right.

The track builds on a repeating loop created with the built-in sequencer on Plinky 12 Toadstep. The short sequence uses rhythmic step repeats, track step length and animated synth parameters to create an ostinato that keeps sonically evolving over the length of the track.

As the piece continues, Roland plays a progression of harmonies from the rainbow chord palette on Plinky 12 Chords, before launching a sequence that reharmonizes the loop heard from Toadstep. Enrica joins in playing sparkling arpeggios with her fingertips on Plinky 12 Blocks, the surface with the sunset colour-fade print.

As the track progresses, Roland plays a melodic line on Chords, then Enrica takes over with a melody on blocks. The Plinky 12 polyphonic play surface reads both play position and pressure of the touch. It enables bends and glides on the horizontal axis, while allowing for discrete arps in the vertical direction.

They end the piece with a tempo transition showcasing the septuplet feature on the internal sequencer."

Inside the 505 String Machine with Dan Chmielinski & Troels Folmann

video upload by Soundpaint

"Get the 505 String Machine here: https://soundpaint.com/products/505-e...

Go inside the making of one of the most iconic string machines ever captured.

Troels Folmann and Dan “Chimy” Chmielinski break down the process behind 505 String Machine, from obsessive ultra-deep sampling to preserving the raw character of the legendary Roland RS-505 String Machine. This is more than a recreation. It is a deep dive into the philosophy, detail, and decisions that bring a classic instrument back to life.

Used by artists like Vangelis, The Police, Depeche Mode, The Cure, New Order, Jean-Michel Jarre, and Herbie Hancock, the RS-505 helped define the sound of an era. Often living in the shadow of the Yamaha CS-80 synthesizer, it was the evolving texture underneath. The movement, the depth, the feeling."

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!

Genki KATLA - THE VOLCANO SYNTH!! Now Available

video upload by Starsky Carr

"What happens when a synthesizer completely breaks the rules?
In this video, we explore the Genki KATLA — a truly unique polysynth inspired by Icelandic volcanoes, featuring a rotating voice architecture, hybrid signal path, and some of the most unpredictable sound design possibilities I’ve come across.

This isn’t your typical analog polysynth. Each of the five voices can run independently with different waveforms, octaves, and modulation — creating evolving textures, harmonic movement, and generative-style sounds that feel closer to modular synthesis than traditional keyboards.

🎛️ What makes the KATLA special?
• Rotating voice polyphony (round robin-style synthesis)
• Independent per-voice oscillators & tuning
• Digital oscillators + analog filter signal path
• Looping envelopes reaching audio-rate modulation
• Phase distortion, wavefolding & multiple distortion types
• Tape-style wow, flutter & pitch instability effects
• Stereo voice movement & evolving spatial modulation
• External inputs for processing other gear

From lush ambient pads to aggressive, evolving sequences — this synth can go places most instruments simply can’t. It’s not about recreating vintage sounds… it’s about discovering entirely new ones.

💸 At around €5000, this is definitely not a beginner synth — but for sound designers, and anyone looking for something truly different, it well worth a look."

"Hey guys! Very very excited to be presenting the Genki Katla to you all... I am truly in awe of the sound of this very unique and powerful instrument.

I thought the best way to get to know the synth is to start from scratch so in this video we'll go full hands-on with the Genki Katla, exploring (almost) every parameter and building sounds from an initialized patch.

From some raw drone layers and gritty textures to evolving pads, rhythmic sequences, and atmospheric beds, we will see just what this instrument can do, discover new sounds, and maybe make some friends along the way 🙏

If you're into sound design, unique synths, or just love discovering new instruments, this one is for you!

HUGE thanks to Genki for letting me a part of this with them and showing off this super cool synth.

No money was paid, no agreements were made... these are my real thoughts on this very premium synthesizer and I will be sharing lots more."

Press release follows:


Genki Instruments announces availability of Katla as Voice Rotating Polyphonic Synthesizer inspired by its natural namesake

REYKJAVIK, ICELAND: having twice blown European musical minds thanks to show-stealing showcases at SUPERBOOTH25, May 8-10, Berlin, Germany and Machina Bristronica 2025, September 27-28, Bristol, UK, before adventuring across the pond for a repeat performance at Buchla & Friends 2026, January 24-25, LA, CA, USA, Reykjavik-based instrument developer Genki Instruments is proud to announce availability of the eagerly-awaited Katla as a Voice Rotating Polyphonic Synthesizer inspired by Iceland’s largest subglacial volcano as its natural namesake — readily representing the company’s first foray into analogue synthesis, albeit one that uniquely utilises a set of wildcard parameters to infuse it with organic, unpredictable behaviour as an instrument that is worthy of that legacy, excelling at generating rich, evolving, multi-layered textures, where each note stirs, swells, and erupts in its own distinct way — as of March 31…

Clearly Katla’s inspiration runs through its ‘volcanic’ veins. After all, it is framed by side panels and knobs forged from authentic Icelandic lava, giving each instrument a tangible connection to the volcanic forces that inspired it. That this synth should surely roar is a given. Genki Instruments inevitably chose, therefore, to kit Katla out with four independent distortion destinations, the most unruly of which is a stereo CMOS (Complementary Metal Oxide Semiconductor) Drive effect — a characterful saturation stage, pushing tones from warm and rounded to fractured and snarling.

Digitone II introduces four selectable synth machines (Wavetone, Swarmer, FM Tone, and FM Drum) and six dynamic filter machines, providing far more sonic variety than its predecessor. The improved 128-step sequencer, along with Euclidean sequencing and advanced modulation options, invites you to explore limitless creative possibilities. Packed with powerful effects, deeper sound-shaping tools, and a modular workflow.

Expanded Polyphony and Synth Machines:
While the original Digitone offered 8 voices and 4 synth tracks, the Digitone II doubles the polyphony to 16 voices and expands the tracks to 16, allowing for far more layered compositions. In addition, the four new synthesis machines (Wavetone, Swarmer, FM Tone, FM Drum) go beyond standard FM synthesis, offering greater creative potential for crafting rich melodic, rhythmic, and percussive sounds.

Enhanced Sequencing and Performance Features:
Digitone II features a 128-step sequencer—twice the length of the original Digitone's—enabling more complex patterns and compositions. The addition of Euclidean mode per track offers a fresh approach to sequencing, making it easier to generate evolving rhythms. With individual pattern length, time scale multipliers, and enhanced trig conditions, the Digitone II’s sequencing features are a leap forward from the original, giving you deeper control over your compositions.

Advanced Modulation and Effects:
The Digitone II builds on its predecessor’s modulation and effects capabilities, with three assignable LFOs per voice (up from two in the original) and added effects like digital overdrive, bit reduction, and sample rate reduction per voice. The inclusion of master effects like the stereo compressor and overdrive means you can fine-tune your final mix, while send effects like Saturator Delay and Supervoid Reverb add depth and dimension to your sounds."
