In 1975, Tom Oberheim revolutionised synthesiser design with the original TVS – Two Voice Synthesizer. By combining two SEMs and a keyboard, he introduced true duophony to the world—enabling musicians to play two independent voices simultaneously and explore harmonically rich, evolving soundscapes. It was a bold step forward, embraced by visionaries including Martin Gore, Adrian Utley, Peter Baumann, Lorn, The Prodigy, and Nils Frahm.
Decades later, the TVS Pro modernised that vision, adding a built-in sequencer, extended modulation, and refined controls—all while staying true to its unmistakable sonic DNA.
Now, with the GForce Oberheim TVS Pro plugin, this landmark instrument enters a new era. Developed in collaboration with Oberheim, this recreation captures not only the depth, warmth and character of the original, but also the spirit of innovation that made it extraordinary.

"What is it? MiniDexed is a high-performance FM synthesizer that replicates the sound of eight DX7 instances, delivering the iconic tones of the TX816 and TX802. Designed to run 'bare metal' on the Raspberry Pi, MiniDexed operates without the need for a Linux kernel or operating system, ensuring efficient and seamless performance. It is assembled into a custom made case, 3D printed. It’s ready for immediate use and compatible with any MIDI keyboard or sequencer featuring MIDI out. By default, its eight modules are assigned to MIDI channels 1-8, but these settings—and more—can be easily customized using the intuitive menu. Used just 3 hours: I had bought it just to compare it to my vintage TX816. I loaded the same sounds in either synth (yes, it loads by MIDI the DX / TX sounds!) and compared A/B. Simply UNBELIEVABLE. For a deep dive into MiniDexed's software and features, please visit this page."

"PX WaveFrame captures the groundbreaking essence of the WaveFrame AudioFrame, a high-end digital sampler and audio production system that made waves in the late 1980s. Developed in Boulder, Colorado, this system was a formidable competitor to the Synclavier and Fairlight, featuring advanced capabilities like non-aliased transposition, phase-coherent polyphony, and 24-bit processing features that were light years ahead of their time. Even with a focus on post-production, the AudioFrame was embraced by forward-thinking musicians and producers for its pristine sound and unique sonic character, with artists like Peter Gabriel, Stevie Wonder, and many others utilizing it for both studio and stage."

Note the "Peterlin" made it's first appearance with Hainbach on May 7 here on MATRIXSYNTH. This post features a few examples from others, and additional details and pics below.
Above:
"In this Signal Colors Palette video, I'm taking a first look at the Ciat-Lonbarde Benjolin / Peterlin, a tiny wooden synth featuring a nod to synthesis history by putting the focus on sound creation with a circuit design inspired by the 'Rungler' by Rob Hordijk.
Hang out while I coax some cool sounds from this wildly experimental sounding synth!"
Quirky little groove machine: Ciat-Lonbarde Peterlin first impressions
"Listen to albums, download tracks and support me at https://noctopolis.bandcamp.com/
I was lucky to get a Ciat-Lonbarde Peterlin (why not Blassolin though?) from the first batch at PatchPoint and these are clips from my first don´t-know-what-I-do-sessions with it. First one: solo. Second one: with Lorre Mill Double Knot 3. Third one: with Moog Subharmonicon."
"first patch ring modulates peterlin xor to vcfq with a sine wave - both controlled by rungler. this is mixed with the peterlin audio output in the vc res eq and its bands get modulated by various peterlin outputs
second and third patches have a bit less and a bit more going on... all gets a little confusing and knotted up
"Dressed in their signature banana jack-laden wooden enclosure, the Peterlin is Ciat-Lonbarde's take on the Benjolin: a tribute to the synthesizer designs of Rob Hordijk. Deceptively simple in appearance, the Peterlin is a highly interconnected instrument containing two oscillators, a resonant lowpass filter, and Peter Blasser's take on the infamous Rungler circuit. Clocked by one oscillator, the Rungler is a shift register feeding upon not only its own output, but also listening to the output of the other oscillator to further influence its data with feedback chaos. As the Rungler's CV output is then fed into the oscillators and filter, a range of hefty drones and chaotic noise is possible. Of course, the Ciat-Lonbarde take on this classic experimental instrument is filled with its own mysteries.
"Sometimes it happens. When I posted this episode a few days ago, Peter Paper commented that 32 bit recordings don't suffer from clipping, distortion and don't need a limiter. I wish that was true, and it turns out it IS! However, many people are still puzzled by it. It only applies to 32 bit analog to digital converters. If your 24 bit converter or analog source clips, there's nothing you can do about it. But 32 bit converters don't have a 0 dB digital brick wall. They just give you all the headroom you'll ever need, up to a range of 1500 dB (210 dB is the loudest possible sound on Earth and it will destroy a city).
I just can't write things that are not true on my channel while knowing about it. So I had to take the old version down and revisit the subject. 32 bit converters are hard to find, but it turned out my little Korg DSD recorder (from Episode 05) can also record 44.1K/32 bit float. So I could test it, and share it with you! The results are amazing. Indeed, it is true! So DSD is a cool 'nerd' feature, but I'll stick to PCM.
Spoiler:
In the blind A/B compare, A is the original 44.1/16 file, and B is the upscaled 768/24 bit version from the Chord Hugo TT2, analog XLR output and re-recorded with the Neve Master Buss Converter in 96K/24. There is a subtle difference in depth, placement, high-end and timing, but I doubt if you can hear it. The purpose of this set is to prepare a digital file for an analog audio chain, but I was wondering if the AD/DA conversion would already make a difference. Considering the price difference, I'd say no. Save your money for a Shared System - but maybe get that little Korg when you love to play loud.

"Unique piece of sound art; this noise machine features paper circuit, Fourses, designed by Peter B.
8% of the profits from this sale will be sent to Peter B as donation/thank you for use of his paper circuits.
104 brass sandrodes and one copper listener node, internal speaker switched off by 1/4” out, powered by 9v battery or 12vdc wall wart (not included), 8 white LED under Apophylite crystal points – one with some Stilbite, 8 knobs, walnut, purple heart and birch, acrylic bottom – protected by rubber feet.
Note, first three photos use flash, which bounces off the beeswax and olive oil used to seal the wood. This makes it appear brighter and redder. Under more normal light, the wood looks darker and more muted. Pics w/o flash give a little better idea, but probably sunlight would be best. Anyways, i'll leave that to you."
"I am pleased to announce a collaboration between EAR and Analog Haven.
The 4HP EAR Model 13 Mini Vactrol LPG KIT for Eurorack
The prices have not yet been determined, but the PCBs have been ordered and will be arriving shortly. ALl of the thru hole components are already in hand
We are producing 200 factory-assembled and 200 kits of VTL5C3 based Low Pass Gates closely resembling the behavior of the original Buchla design. Due to the largely unobtainium status of the proper vactrols this may by your last opportunity to purchase a Buchla based LPG. The factory pre-asembled modules will have green soldermask and metal photo process aluminum faceplates. The kits will have black soldermask PCBS and a FR4 black faceplate, of which there will be 2 variants - both priced differently:
A. A kit containing 1 Faceplate, 1 Main PCB, 1 Pot PCB, three jacks, three 1mm thick metal washers, 1 100K linear pot, 1 Davies-type push-on T18 black knob, 1 momentary pushbutton and a link where to purchase the SMT parts referencing both vendor and Mouser part numbers. Expect $12 in parts is purchased through Mouser.
B. Same as above including two vactrols. However, these will not be available until after the factory-built units have been completed.

"I am Peter Grenader - the designer, curator and sometimes sound designer for Danny Carey's Toolbox, the modular system used live with Tool (Chocolate Chip Trip).
I recently did a huge overhaul and expansion of that system and this video details that journey.
For a recent interview detailing this system and my involvement with Tool, check out Kris West's Spiral Out podcast:
"This is a lively Sunday morning jaunt with my newly acquired Beads... which, as silly as this may be, is offscreen in this video.
I know, lame.
Hear me out! The Mutable Beads is currently kicking the crap out of me. I have no idea of it's capabilities. It's all hunt and peck at this point. In one of those experiments, i noticed by putting a metric rhythm patch through it and syncing the Seed input with the same clock that's driving the patch that it would, magically, double the frequency of whatever it's processing.
This immediately reminded me of a certain passage Mort Subotnick is famous for, so i ginned up a quicky sonic xerox. This all came about after i produced a demo of what 'real' lowpass gates can do, which hearkened back my percussive motif fetish that dominated my piece The Secret Life of Semiconductors (search 'Peter Grenader Secret Life" on apple music or bandcamp if curious).
Everything you hear is being gated through vactrol-based LPGs, namely the Plan B Model 13 Timbral Gate. The first voice is from a Flame 4 Vox in which i cycle through a few of it's wavetables. The second voice is it's manifestation via the Mutable Beads in which i am controlling the wet/dry mix via Plan B Model 24 wiggly random voltage. The third voice is via a Plan B Model 15 which is getting it's pacing from Malekko Varigate 4.
Panning courtesy of an EAR Model 7 Panner, driven by a second wiggly random via a second Plan B Model 24
The first and third voices are being driven by two Plan B Model 10 EGs to both open the LPG and thwap the VCO frequencies.
As i sidenote, i think Apple finally chased all the demons out of iMovie. It does not piss me off anywhere near as much now.
7" Radio Edit - Glorified Lyric Video video upload by Alex Simesky
A new track from supporting member Alex Simesky who had the following to say about the release:
"The genesis of Such Imperfection comes from a demo tape that I did a few years ago. At the time I had eliminated the computer from the studio to get back to my roots - recording synth demos on cassette tapes. The original groove was recorded with Roland TR-505, MS-20 and electric guitars. This idea was then expanded using some of Arturia's V Collection synths like the SEM V (bass), CZ V (pads) and Emulator II V (drums and bass). A once in a lifetime encounter with Fritch lead to the finished track, for which he came up with the lyrics and the vox."
And the description with links from the video:
"A future retro love-letter to gloss-polished pop, neon nu-wave and cool indie.
As the decades collide from The Cure, Peter Gabriel and Brian Eno to Tears for Fears, Royksopp and Robyn, every sweetly honed sonic shines sultry. And in extending that love letter to the best lost tradition of A-side and B-side 80’s vinyl, the 7” edit arrives with a full 12” mix that weaves synthwave with prog-glam and grandeur. This is lo-fi turned hi-fi and glistening.
Living in Belgium, United Simesky Institutes has worked with Budapest Scoring Orchestra and scored high with releases of sweet 80’s synthwave amongst the ranks of Vice & We Write About Music. Fritch comes from Wales, and comes fresh from an album that gained 5-star comparisons to Bowie’s Blackstar and Scott Walker. This is music that moves across boundaries, this is UK and Belgium combined.
But right here a new cult is created. Right here is a new sound entirely.
With shared production, shared writing, shared artwork, shared visions, the debut single from Simesky+Fritch is a celebration of a meeting of minds. It’s a lean synth-kissed passion for pop.
I think people who haven't yet done a lot of PCB/faceplate design and integration will appreciate this.
As some of you know, i was the designer of and now the lion tamer for the Euro system used by Tool live (Chocolate Chip Drip). I had to make them a single channel attenuator with very little time left b4 they leave on their new tour and didn't have a lot of free HP in which to do it.
This video goes through the process to make sure things align perfectly when there is no time for rev. 2
