12/17/25 Zerosum Inertia ZI54 + Trogotronic 676 + RYK 185 (System 100m) + Alesis MIDIVERB II

video upload by Cfpp0

"A little montage of three horrendous fanfares while testing power supplies. The Monorocket Mission6 case has been emptied and the Zerosum Inertia ZI54 and Metasonix RKP have been moved to the racks, where the Moog Subharmonicon used to be installed. We almost sold the amazing Trogotronic 676 and two 11 VCA controllers, but they’re staying. Those, plus a Zerosum Inertia 6AS6 Signal Combiner, have been added to the same rack, as they all sound great with the Roland System 100m. There is also a Doepfer Quantizer, mainly for the Roland 182 sequencer we got recently. The reverb is from the MIDIVERB II."

Custom White Roland Juno-106 61-Key Programmable Polyphonic Synthesizer

Note: links to listings are affiliate links for which the site may be compensated.

via this Reverb listing

"Custom Roland Juno 106 serviced, painted, and modded by the synth spa in late 2017. This Juno 106 is super clean, works perfect perfectly, and is one of a kind. The color is cream and all the graphics, program lights, and mod wheel are all custom. Synth spa also socketed the main processor so it’s easily removed if you should ever decide to do the kiwi. The sides are Custom too but kind of wish I would’ve gone with a matte/satin finish because they’re a little overly glossy(see pictures,) but still nice. This synth is in great shape and playsas it should. If you’re familiar with this synthesizer, it’s the voice chips that can go bad but these were fully restored when this synth was customized and should continue to stay strong for a long time."

This is Not Rocket Science (TiNRS) Workshop ‪@schneidersladen_berlin‬

video upload by SchneidersLaden

"On November 20, 2025, This Is Not Rocket Science (TiNRS) visited our showroom in Berlin. In this recording of the evening, Priscilla and Stijn Haring-Kuipers present their latest Eurorack modules, the legendary Fenix IV, and provide insights into their creative applications for experimental sound design.

Special attention is given to modules such as BOPP & STEVE, which beautifully demonstrate how far reverb and effects processing can be taken in a modular context. The presentation is complemented by a live performance by Serge Jansen, Priscilla, and Stijn, who use TiNRS modules in a hardware-based modular live set and demonstrate their strengths in a stage context.

Recorded at the SchneidersLaden showroom, Berlin-Neukölln."

Quick No-Talk Synth Demo

video upload by Autodafe

"Here’s a fast, no-talk demo of SQUID-3 (SQ-3), the new synth by Acustica Audio. This video is all about listening: no voice-over, no explanations — just sounds and visuals so you can get a first impression of what this synth can do.

In this demo I’m simply showcasing a selection of patches and musical textures. I’m not going into technical details or deep sound-design features this time — think of this as a relaxed, musical overview rather than a tutorial.

If you’re curious about the engine, workflow, or a more in-depth breakdown, feel free to leave a comment and I may cover it in a future video. For now, just sit back and enjoy the sound."

SQUID-3 is a forward-thinking synthesizer born from Acustica’s groundbreaking MAREA series, available in VST3, AU, and AAX formats. Built to respond better than a real instrument, SQUID-3 gives you the speed to create instantly, and the depth to design without limits. It’s fluid, focused, and sonically honest.

This isn’t a vintage emulation, or a collection of pretty presets under reverb.

SQUID-3 fuses algorithmic modeling with advanced convolution, capturing the behavior of analog gear - better than gear does.

SQUID-3 is not another virtual synth.

It’s a new breed - designed to sound finished, even before the FX.
Every stage of its engine, from oscillator to output, was built to make raw synthesis sound like a mastered record.

SQUID-3 is available in two separate editions:

• the Standard (3-D, multi-page) edition, hardware-inspired interface with depth, lighting, and tactile realism for an immersive studio feel.

• a Flat (2-D version, single-page) edition, A clean, flat design optimized for speed, built for maximum graphic efficiency, where all controls are summarized on a single page"

Tonverk 1.2.0 OS Upgrade

video upload by Elektron

"Tonverk 1.2.0 is here! With some lovely little festive additions to put under the Tonverk tree. We’ve got two new FX to play with, even more options with the existing FX, random mode for the arpeggiator, and further fixes and improvements.

Find out more and download Tonverk OS 1.1.0: https://bit.ly/48T1BjG"

"OS Upgrade: Tonverk OS 1.2.0
We know Grainer, and the 1.1.0 OS that fixed the sync issues, are still fresh on the block, but we had some pretty neat dishes in the oven that didn’t quite make that release. So here is OS 1.2.0, a chance to put a few more little festive additions under the Tonverk tree. We’ve got new effects, even more options with the existing effects, a random mode for the arpeggiator, and some other little additions alongside further fixes and improvements.

New effect: Steel Box Reverb

A third reverb comes to Tonverk, and it’s a whole other flavor. Steel Box Reverb draws on early digital and ’90s plate reverbs, with deliberately wide parameter ranges that let you push sounds from tight metallic rooms to sprawling, resonant spaces. It can clang, bloom, or decay endlessly, making it equally suited to metal can tails or big, characterful ambience.

New effect: Filter Folder

Filter Folder combines wavefolding with filtering and distortion to reshape sound at a more fundamental level. By folding the waveform before it passes through a multimode filter and drive stage, it adds harmonics, grit, and movement that go far beyond traditional filtering. From subtle edge and density to aggressive, overtone-rich transformations, Filter Folder excels at turning simple signals into something far more complex.

More FX availability

If those two additions weren’t enough (for now) we’ve also extended Tonverk’s FX powers in other ways too. Daisy Delay can now be used on all tracks - and Frequency Warper can now be wielded on all audio tracks, bus tracks and mix. Use these two awesome options wherever your echoing, warped heart desires.

Random Arp

Random Arp introduces controlled unpredictability to arpeggiated patterns, reshuffling note order on the fly to generate evolving melodies and unexpected variations.

And more

There’s a few other stocking fillers too. Pattern mute, improved gain reduction and new sidechain sources for the compressor, shorter samples available to use on Grainer, and improved tempo stability when simultaneously receiving clock and large amounts of MIDI data from an external source, such as Octatrack. Plus various other fixes and improvements."

New Open Source Virtual Pipe Organ Project: Rusty Pipes

This one is in via DS:

"Hey Matrixitians!

I'm writing in to announce a new MIDI-controlled Virtual Pipe Organ software called "Rusty Pipes".

It's a sample-based organ synth with support for GrandOrgue and (unencrypted) Hauptwerk sample sets. It features 32 bit internal audio mixing, full MIDI support with extremely flexible channel routing, integrated audio and MIDI recording of performances, convolution reverb, and an innovative sample streaming mode that makes it possible to play very large sample sets with a minimal amount of RAM, yet without increasing latency!

Other unique features include a REST API for things like pulling stops - great for people who like to build physical consoles - and optional text mode support (via Ratatui) which makes this ideal for running on headless setups or on a RaspberryPi.

Rusty Pipes is a clean-room implementation written 100% in Rust, available free and open source under the GPL v2. Version 1.3.0 supports over 20 languages including Latin and Klingon, and is available for Linux, Mac and Windows. Debian and Arch (AUR) packages are provided as well.

c.1982 MPC “The KIT” Integrated Electronic Drum Machine

Note: links to listings are affiliate links for which the site may be compensated.
video upload by riffers

via this Reverb listing

"Early British classic with that gritty, punchy analogue character.
Recently serviced: every pad triggers reliably; no noisy pots.
Original flat-pack box included. All-original hardware.
Serial (no. 242) on chassis; “Made in England” plate intact.
Set a tempo, balance the per-voice levels, and you’ve got a solid groove in seconds—no menus, no programming detours. The tactile pads invite quick ideas (fills, accents, breaks) and the adjustable pad sensitivity lets you dial in the “human” feel that helps parts sit in a song. Its distinct British analogue tone layers well with samplers/DAWs: track it straight in for gritty loops, one-shot it for kits, or re-amp it through pedals for textures. It doubles as a dependable writing click with character, so riffs and basslines arrive faster.

Fast, hands-on layout. Front-panel rotary controls are primarily per-voice level/volume (plus master TEMPO and LEVEL).

Pad feel is responsive; use the rear trimmers to dial sensitivity for dynamics or hard, machine-tight hits.

Multiple 1/4" jacks along the top panel for audio connections (see close-ups).

Power: 9V battery operation or 9V DC mains adapter (PSU not included).

Condition

Fully working. Pads all trigger; sensitivity trimmers on the underside let you set your preferred feel. Cosmetic wear from age and use: scuffs/scratches and some discolouration; a few rubber feet missing (see photos).

Included

MPC the KIT unit
Original flat-pack/knock-down box"

Selmer Companion Electric Reed Organ SN 152

video upload by riffers

via this Reverb listing

"Selmer Companion reed organ from the 60s. In tune and wonderfully “parlour-harmonium”: bright, reedy mids with a gentle breathiness on the attack, then a steady, organ-like sustain from the blower. The chord buttons give an instant drone bed with that slightly nasal, woody timbre that cuts through without ever getting harsh. Think small chapel/folk harmonium vibes—perfect for drones, hymnal pads, psych-folk textures, lo-fi soundtrack cues, and vintage pop hooks. Hear it in the demo (skip to last photo). Typical vintage tuning and keybed feel; expect minor variance vs modern concert pitch.

Features

Classic electric reed organ with compact keyboard and built-in blower/speaker
Left-hand chord section: Major & Minor buttons (C, G, D, A, F, B♭) for instant accompaniment
On/off/level control, integrated flip-up music rest in the lid, suitcase-style cabinet with carry handle 1960s/70s Italian vibe: gold fascia, cream case, and period hardware
Sounds exactly like you want a small electric harmonium to sound—see the demo"

"Serial Nº 21196

Italian-made CRB “Diamond” Cavendish Combo 30 in remarkable condition for its age. Classic combo-organ tones plus a built-in “mini-band” (bass + drums) make it a fun, self-contained writing and performance machine. Built in Ancona under CRB’s Diamond/Cavendish line.

Organ section: Flutes, Clarinets, Reeds, Strings

Presets: Piano, Spinet, Harpsichord

Effects: Sustain and Vibrato (both sound great)

Mini-band (auto-accompaniment)

Drum patterns: Waltz, March, Tango, Bossa Nova, Samba, Slow Rock, Boogie, Disco — all with variable tempo/volume; very much in the vein of early CR-series drum machines.

Bass accompaniment with automatic chords, Free 1-Finger, Memory, and chord quality switching (Major default; Minor/7th via yellow/green buttons).

External output, headphone out
Expression pedal input
Built-in speaker that’s quaint yet surprisingly punchy
UK mains power - we can include a step-up/step-down transformer on request so you can use it in your country without modification, just ask for details."

(Video) *Serviced* 1970s Wersi Entertainer Compact German Combo Organ w/ Big Rhythms

Note: links to listings are affiliate links for which the site may be compensated.
video upload by riffers

via this Reverb listing

"Back with another charmer: the Wersi Entertainer—that unmistakable 1970s/80s German home-organ vibe in a slimline, wood-cased package. Heavy, driving rhythm section (like only the Germans can), lush organ tabs, and built-in speakers for instant fun.

Set a tempo, punch in a style (March, Samba, Slow Rock, Waltz, Beat, Swing), and layer chords with Auto-Chord while you hunt melodies on the upper keys. The rhythms are steady and weighty enough to act as a “groove grid,” so song ideas arrive quickly. The on-panel balance/volume lets you sketch arrangements (pad vs lead vs rhythm) in seconds, and the bold, simple voicings sit in a mix without fuss—great for writing hooks, auditioning progressions, or tracking guide parts straight into a DAW.

Features

Voices via coloured tabs: Horn 16', Tibia 16'/8', Klarinette, Perc 8', Vibrato, Auto Chord.
Rhythm presets: March, Samba, Slow Rock, Walzer, Beat, Swing with Start/Stop and Tempo.
Onboard stereo speakers for plug-and-play use.
Rear panel: pitch trim, external amplifier output (DIN), 12V battery input, and external speaker connection.
Compact, wood-veneer cabinet with Wersi badging.
Rear panel: external amplifier out, 12V battery input, external speaker out (2–8 Ω), pitch trim.
Condition

Fully functioning: all keys, tabs and rhythms tested and working. Clean overall with light cosmetic wear consistent with age; see photos for close-ups."
