"This video is all about cool things you can do with some basic utilities in a modular synth. In particular, I want to explain how you can massively expand the sonic range of a basic oscillator with a few simple tricks. I’ll show you a couple of ways to use sample & hold, both at audio rates and for more subtle ‘humanising’ modulation. I’ll explore using a rectifier to create octave-up copies of simple shapes and to transform basic waveforms in more radical ways. I’ll go into extreme PWM territory with a comparator, as well as using it for some pitch-dependent switching to spice up sequences. And I’ll show you how you can use analogue logic processing to turn a mono oscillator into a stereo one."

2. VoxModula Archives – The Beginning of an Archive
Hi, this is the first video of VoxModula Archives. VoxModula is an ongoing collection of sonic fragments — recordings where synthesis meets the quiet presence of the surrounding world.
Each piece is an observation of sound as a living material: unstable, imperfect, shaped by voltage and time.
The project does not aim to perform or entertain, but to document the space between intention and accident — where tone becomes memory, and noise becomes evidence of existence.
These works are presented without manipulation or spectacle, as if retrieved from an open archive of moments.
"This is a live performance on an original Buchla 100 from the late 1960s, using the Concrete Box™ , and TX-6 mixer
The patch uses 3 loopers and 2 delays, plus a very old Dynacord VRS23 reverb (which is adding some slightly woozy pitch-bendy-ness to the reverb)
The Buchla has a really basic patch - just one Sine-Saw VCO into the Sharp Cutoff Filter (Lowpass section). There's some cutoff mod from the keyboard capacitance voltage (which is why I'm wiggling my fingers in a rather silly-looking way)
The vintage Buchla 100 sounds so natural, rich and organic, I love it - almost like an acoustic instrument - a brassy, beautiful tone from the saw waves
Also, there's a second VCO (square) going into the HPF section of the Sharp Cutoff Filter (which is independent from the lowpass section in this mode) for the low drones
It builds up a bit like the many fallen leaves which have accumulated upon the now wintery lawn I am gazing upon"

Check with dealers on the right for availability and price.
"Bastl CITADEL - Fortress of Modular Magic - is a Eurorack reimagination of the popular Kastle 2 semi-modular desktop device. The CITADEL comes with a full 3.5mm patch bay that offers the flexibility needed in the Eurorack format while maintaining the strengths of the Kastle 2 allowing it to stand on its own, and yet let it truly shine when patched with other modules. We’ve also added switches for hands-on control of the pattern generator. The Citadel provides the basic infrastructure needed to integrate Eurorack systems within the context of electronic music making: headphone output, TRS MIDI input and sync, tempo generator with divider/multiplier, USB MIDI (from the back of the module), stereo mixing, integrated LFO and Pattern generator and effects. All that makes it the perfect module for smaller and beginner systems while the fun and unique creativity of the Kastle 2 firmwares: the FX WIZARD multi-effect processor and WAVE BARD sample player will earn its place in larger setups.
🛠️ Get Wave Bard & FX Wizard at the same time 🔃 The Citadel comes equipped with a reversible front panel with WAVE BARD on one side and FX WIZARD on the other side. It also comes with our custom designed tool to make the panel switching as seamless as possible. You can load and try different Citadel/Kastle 2 present and future firmwares and updates with a USB port (on the back).
The Citadel might break a few rules of standard Eurorack design, but it does so in the name of instant musicality, fun, and effortless integration of Eurorack with other gear. The PITCH inputs on the WAVE BARD track 1V/Oct, are factory-calibrated, and there’s even dedicated calibration software to ensure a perfect match with your source."
"Here we have Ferry Island Modular's first release 'Four Seas', which is designed, engineered and manufactured in Finland. It's a real power house of a sound source, suiting to quickly grabbing some waves to patch with or for deep sound design tweaking. Everything is knob/button per function with no menus, making complex behaviours, modulations and sounds simple to access. There's LOTS of examples in this video, see the timing index below for all that's covered ... yet I'm sure there's lots left to uncover with all the options this presents."

Pics and videos featuring some of the gear below, and his Lederhosen for good measure (thanks greg!).
Update: the post has been fully updated with all the synth related gear. This may just well be the longest post to be featured on the site. I wanted to capture all the pics for all of the details including notes, scuffs, and of course serial numbers. It's an interesting look into what he used, the condition he keped his gear, in some cases, how he actually used his gear. Note the phonetics on the keys of the Casio CZ-101 and DX-100. Note the Midi Switch Box with a built-in speaker? What's that about? Note the camouflage key strap on the Korg RK-100 Remote Keyboard. Did he pick it out himself or did the keytar just come with it? Note the repeat midi controllers and the MIDI saxaphones. Wind was his primary instrument. You'll find a ton of the acoustic gear he used in the other listings. This is a fascinating insight into both what and how he used his gear.

Rack Mount Sennheiser VSM-201 Vocoder
Starting Bid
$5,000
Estimate
$20,000 - $40,000 USD
A late 1970s Sennheiser VSM 201 Vocoder with no serial number from the personal studio and collection of Florian Schneider of Kraftwerk (see images). While it’s said that only a few dozen of these Vocoders were produced, a few examples made it into the hands of forward-thinking musical artists including Herbie Hancock, Daft Punk, and of course, Kraftwerk, who used a VSM-201 like this on their albums Man Machine (1978) and Computerworld (1981). The VSM-201 has an intelligible sound that has not yet been bested by modern gear. Includes power cable. This VSM-201 has been removed from its wooden enclosure (which bears the serial number plate) and modified with a metal rack mount casing, presumably for live use. Requires 240v, IEC power cable not included.
Dimensions: 19 x 9 x 9 inches
Category: Kraftwerk, Equipment
Provenance: PROVENANCE From the Estate of Florian Schneider
"Similis is a lo-fi synth that has several different patches. Here it is set to run a random sequence over a major or minor scale. This preset can be switched between 1 or 2 oscillators, each playing a random note independent of each other.
Pot A/CV in A sets the root note.
Pot B/CV in B sets the range of notes of the chosen scale.
Pot C/CV in C sets the rate of the sequencer (controlled using an envelope generator in this example)
Switch A sets the waveform (Sine, Saw or Square)
Switch B has 3 different settings (Stop the sequencer playback on its current note, run the sequencer, run the sequencer and add an additional synth voice.)
Switch C sets the scale."
"Similis is a lo-fi/chiptune style synth consisting of several different presets.
This Similis patch stacks 3 oscillators and detunes them against each other.
Pot A/CV in A controls the root note.
Pot B/CV in B controls the detune of the other 2 oscillators.
Pot C/CV in C controls the level of the 2 additional oscillators.
The root note pitch is being controlled by a random scale from Pam's Pro Workout.
Here an envelope generator is controlling the level of the detuned oscillators through CV in C.
Switches A B and C change each oscillators waveform (sine, saw, square)"
"Similis is a lofi synthesiser that has 6 different presets.
This is an example of the 'chord' preset.
The first control sets the root note of the chord. The second selects 1 of the 10 chords available (5 major variations and 5 minor). The third control sets the volume of the notes that make up the chord except the root. Each of these controls has a CV input.
Here the root note is controlled by the keystep pitch. The VCA is being gated by the keysteps gate out.
The volume of the chord notes are controlled using the mod wheel."

"Similis is a lofi chip tune synthesiser that uses basic waveforms to generate it's sound.
Features:- 6 different settings (TYPE) from stacked oscillators to chords to self sequencing. The setting selection can also be stepped using a trigger/gate signal for some odd patch skipping.
Each control can also has a CV input for connecting external gear.
Settings 1-3 deal with stacked oscillators. 3 oscillators with independent pitch. Sine, Saw and Triangle waves. 3 stacked oscillators. The first sets the root note and the other two are detuned plus and minus from the root. The two detuned oscillators can be faded in. Chords. The first oscillator sets the root note. The second control sets the chord (5 major chord variations and 5 minor) The amount of voices in the chord can be altered using switch C. The chord notes can be faded in to give a swell effect. Settings 4-6. Simple sequencing. The last three patches are random sequencers. The first is free running. Select between, chromatic, major and minor scales. The range and rate of the sequence can be altered and a second oscillator can also be brought into the sound. The last two patches substitute the rate control as a mix for other voices. A short trigger signal is needed to tell Similis to choose a new random note/s within it’s selected scale.
The output is run through a 3 position passive LPF which turns into a Low pass gate when the VCA switch is down and a CV signal is connected to the VCA input."
"More work on the SID module. Another 3 channel test. Those chorus sections 🔥👌❤️
The meow song (love action) by the Human league....
The floor is lava.. Baba is you... And Armalyte is Alleykat 🐱🐾🐾🐾
Project Armalyte is now called Alleykat. My long time feline companion, Maddie, passed away two weeks ago. She would sit and chill with me for hours while i coded and toiled away on this and other projects. She'd see me off when i went to work and be waiting for me when i got home. She'd ride around on my shoulder, sleep on my bed and follow me everywhere. From the scared and timid cat who had a massive alopecia bald patch on her back and who i think had had a bit of a bad life as the frightened girl who crept into my shed all those years ago, she became a gentle, funny and loving companion. She was 18, she was my friend for many years, and i miss her 😔
The module is now a tribute to kitty cat. And she'll be appearing on the back of it.
Nine lives - no regrets ❤️
Nice cover of the meow song for her. When the module is complete i'll come back and tweak it for a proper demo, where it will be paired up with the song 'tell me when', which also has a meow in towards the end 😂
Sounds somewhat like a Hubbard outing for the verses, but then you hit the chorus and it goes full sublime Galway - Ocean loader. It sounds wonderful. in a kept in the loft for 30 years way 😊
Tuning is still as crap as my Korg Monopoly on a good day. But a bit of pitch bend wheel keeps it sweet enough. The day i move it off the breadboard and get a precision reference in there for 1voct tracking can't come soon enough.
Currently waiting for some parts to make the next big leap. This is where the last few registers will become active and all the ringmod/sync/wave mixing kinds of things will come to life.
Than chorus though.. I fucking love this thing..... The nostalgia feels are something else ❤️❤️❤️"
"While designing a patch on the MicroFreak, I stumbled upon a strange sound — absurd in a good way — so I turned it into a jam. Now and then, it gives off a Steve Vai–like vibe (3:13-), which I love.
Starting from the init patch, pitch and timbre shift with LFO and pressure. The sequence was entered on a whim, following instinct more than logic.

PoliMATHS [MSRP: $459] is an eight-channel CV and Audio event generator for the New Universal Synthesizer System or any Eurorack modular synthesizer. It uses a single set of controls to generate complex functions at eight independent channel outputs. PoliMATHS’ functions are made up of two components: first, the well-known Rise-Fall envelope with variable Curve (familiar from the original MATHS and Function and 0-Coast Slope); and second, a variable-Shape Oscillation whose amplitude is controlled over time by the Rise-Fall envelopes. This oscillation can be either low frequency for the creation of complex control functions, or audio frequency for native generation of audio events/notes with optional tuned pitch control via 1v/oct control voltage. PoliMATHS also includes output headers for creating pre-patched connections to the control inputs of QXG.
PoliMATHS Part of the New Universal Synthesizer System Eight channel function generator with a single set of controls Create simple or complex functions Activate channels in many possible patterns using Channel Index, Round, and Parallel Modes Modulate parameters across channels with Spread or Modulation Dissemination Designed to work with MultiMod and QXG and future NUSS modules Chain to QXG for immediate eight channel amplitude control
The Quad Stereo Gate (QXG) [MSRP: $239] music synthesizer module is a Four Channel Stereo Low Pass Gate and Mixer. Like the DXG before it, the QXG utilizes a new low pass gate circuit that does not use vactrols. This circuit is 100% analog and its response was arrived at after many months tailoring it to meet or exceed the expectations that have been set by all the vactrol low pass gates that Make Noise has created over the years. Additionally the QXG adds a Vactrol button to select between a Slow, low-pass-gate-like response emulating the decay time of a vactrol (Vactrol button ON), and a Fast precision response that still maintains the gentle filtering characteristic (Vactrol button OFF). Fast response can be especially useful when patching QXG with complex and quickly-changing functions such as those generated by PoliMATHS with the OSC circuit in use. The QXG also includes a Stereo Sum Output with voltage controllable Stereo Spread to quickly route all four channels across the stereo field. Each channel also has an individual output that removes the channel from the Sum when patched. In addition, QXG includes signal and control input headers for creating pre-patched connections from the outputs of PoliMATHS and MultiMod.
Part of the New Universal Synthesizer System Four channel low pass gate Vactrol-free design for classic Low Pass Gate sounds Vactrol button to select Fast or Slow response Xpread parameter for spreading the four channels across the stereo field Summing stage with Stereo AUXiliary IN allows for chaining of multiple units, creating larger mixes Individual channels can be removed from Sum by patching to their respective outputs Designed to work with MultiMod and PoliMaths Chain two QXG units to a PoliMaths for immediate eight channel amplitude control
PoliMaths & QXG | How does it sound when you know nothing?
"Today MakeNoise has introduced PoliMaths and QXG. My dealer already had them in stock (!) and allowed me to buy them - under the strict condition to keep it a secret until after the official launch video. So I had the opportunity to make a video in one day, without access to any help from the manual or the MakeNoise launch video. Normally I'd do my homework first, but this opportunity is rare. Usually, I can intuitively figure out how a module works, but with PoliMaths, almost nothing is familiar, and what's familiar works differently. So I've probably been using a MonoMaths, but since I decided to get two, there's still a Poli vibe to it.
This is probably one of the worst videos I've made so far, but it's fun to patch in the blind with zero knowledge, and this was the only day I could record, edit and post it. So forgive me for being a MakeNoise groupie. I am biased, but I also think it's for a good reason. MakeNoise managed to make something extremely innovative. I'll make a proper video soon, and I'll figure out what to do with this one later."
"A true piece of synthesizer history, the Moog Source (early 1980s) was Moog’s first synthesizer to feature programmable patch memory—a groundbreaking step that combined classic analog warmth with futuristic digital control. Revered for its lush, fat Moog tone and its pioneering optical alpha dial interface, the Source is both a collector’s dream and a player’s powerhouse.
This unit includes its original factory presets on cassette, the original owner’s manual, preset sheets, and the original schematic—a complete package that rarely surfaces.
Key Features:
Monophonic analog synthesizer with dual oscillators per voice 37-key keyboard (C–C) with octave shift & pitch/mod wheels Oscillators offer sawtooth, triangle, and square (with PWM) waveforms Oscillator sync + noise generator for deep sound design potential Classic 24dB Moog Ladder Filter with self-oscillation & keyboard tracking LFO with multiple waveforms routable to VCO or filter 16 patch memory slots + cassette storage for presets Innovative optical alpha dial with LED display—clean, modern interface design"
