X1L3 - ALLEYKAT - DEV - NINE LIVES - NO REGRETS - module test build - swinsid - eurorack module

video upload by X1L3

The ALLEYKAT gets a front panel.

"First and flawed test build of the Alleykat module.
Nine lives - no regrets......

Completed the next schematic revision today ready for submission to fab. In doing so i ended up spending an hour on this flawed test piece knocking this up for a bit of fun.

When you consider how good it sounds (in a c64 kind of way) in it's current state, it becomes quite obvious how cool it will be when the filter is online and all the parameters are active. The test boards had numerous errors on them which have rendered the ring/sync and octave hopping inactive. The filter cutoff and resonance were also mis-routed in the schematic which rendered the filter unusable.

Swinsid in circuit this time. Does a decent enough job, but i've yet to see how it performs in comparison to a real SID or a superior clone when the ring/sync and filter come into play. The only difference i hear using just the waveforms and pwm compared to the usual 8580 i use for testing is that the swinsid doesn't sound as bright.

With a bit of luck i've fixed everything that was wrong with the first attempt and the next revision will work properly."

Dirtywave M8 Tracker // Atmospheric First Sketch

video upload by Dexba

"Only good things to say about the M8 Tracker.
I briefly owned the mk1 version (which I still prefer from a purely aesthetic standpoint: it was so cyberpunk!), and I had many plans for it, including a convoluted recording featuring the Wingie 2 outside, but I had to sell it because, as usual, money!
Now we're back with the mk2, which, aesthetic preferences aside, is better in any way: usb-c, battery, structural integrity, comfort in the hands, and I am starting again from zero.
The reverb now sounds way better, I have a tiny bit more experience with trackers, and I've digested hours of tutorials (but I am still scared of using Tables, lol)
It might seem a very basic jam, and it probably is for seasoned users, but I want to treat this channel as a diary for my journey with the various instruments I try, so here is my first sketch!
Recorded with the LOVELY 'Render' feature, which should be almost mandatory on all the digital grooveboxes around (OPXY, I am looking at you...)
Hope you'll like it!"

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."

Animal Factory Dirty Mirror × Korg Monologue // Fuzz Synth Jam (No Talking)

video upload by Animal Factory Amplification

"Use headphones for this one! Animal Factory Dirty Mirror dual parallel fuzz pedal running a Korg Monologue analog synth — no talking, no post-processing, just raw tone. This was recorded in one take to bring out how the Dirty Mirror becomes an instrument in itself.

A love letter to shoegaze, noise, and harsh textures, the Dirty Mirror pairs a modified Shin-Ei Superfuzz (the "Burn" channel) with a heavily modded Big Muff Pi (the "Churn" channel), plus a pre-fuzz delay modulated by an internal LFO and envelope follower. Hand-built in Mumbai by Animal Factory Amplification and debuted at Superbooth 2025.

Here it's sculpting the Korg Monologue's aggressive analog voice into fuzzscapes, drones, seasick vibrato, and pitch-shifted square-wave chaos. Recorded dry — no EQ, no reverb, nothing but the pedal and the synth. Drums from an MFB Tanzmaus (not processed)

Animal Factory Dirty Mirror Fuzz on MFB Tanzmaus | Dual Distortion Delay Jam

video upload by Animal Factory Amplification

"Use headphones or speakers with good bass! Dual fuzz chaos meets beat-driven synthesis! Watch the Animal Factory Dirty Mirror transform the MFB Tanzmaus drum machine with creative distortion and delay manipulation. This is pure experimentation—no tutorial, just sonic exploration.

Gear featured:
Animal Factory Dirty Mirror Dual Fuzz Pedal
MFB Tanzmaus Drum Machine

Not just a shoegaze and noise rock machine - the Dirty Mirror is the perfect fuzz for musicians exploring wall-of-fuzz sounds, experimental synthesis, drum machine effects processing, and unconventional gear combinations."

"The Dirty Mirror takes these two behemoths of sonic perversion and adds an extra layer of nasty – using the core circuit of our Coma Reactor Eurorack module.

This three footswitch, 15 knob pedal looks complicated – but it’s not:

The BURN Channel (left side) is based on our Chemical Burn circuit, a nastier FY-6 variant.

The CHURN channel (right side) is based on a heavily modded Big Muff Pi.

There is a short delay circuit before the fuzz circuits.

Both the fuzz circuits can switch between the input sound, 100% wet delayed sound or a blend of wet and dry.

The fuzz circuits are then mixed in parallel into a high-headroom output section.

For added sickness, the delay time can be modified by an envelope follower or LFO.

Choose your filthy reflection – from straight dual parallel fuzz textures, to seasick vibrato to long slow quasi-chorus phasey apocalyptica.

The delay can be used on its own for slapback, chorus and vibrato effects.

Yes, it can get very noisy.
No, you can’t do anything about it - so weep in pain and pleasure, and submit to the swarms of square waves that joyfully fill your room."

New Kodamo Mask1EX MK2 Bitmask Synthesizer ~ Jade Vine Limited Edition

video upload by Kodamo

"The Mask1EX desktop synthesizer is back, with new looks and new features! Mask1EX MK2 offers 14-voice polyphony with two Bitmask oscillators for each voice - Bitmask Synthesis is exclusive to all Kodamo's Mask synthesizers, it produces a wide range of unique tones by using a single number as parameter. Mask1EX MK2 also has built-in effects, a looper, an arpeggiator and much more."



"It is back, with a totally new design, more powerful than ever! The Mask1EX is a desktop synthesizer that you can use with your keyboard, DAW, sequencer or any other gear with MIDI. Like other Mask synths, it is based on our exclusive Bitmask synthesis technology which generates up to 512 different waveforms for oscillators.

Intellijel Swells | Four synth explorations

video upload by Jay Hosking

"Four mostly ambient pieces with Intellijel's new reverb and other hardware.

Fair warning: Intellijel sent me the Swells and Jellymix. Take that as you will. Considering how much other Intellijel stuff I use, and considering how much I'm a sucker for reverb, I was excited to try this one out.

00:00 - Omnichord ambient
03:49 - SubH Replay ambient
08:22 - S-4 OVUM ambient
12:35 - Hexdrums jam

Undoubtedly, we're living in a golden era of reverb hardware. I've got more reverb than one human needs, but I love it so much. One thing that means, though, is that I'm looking for reverb that does new things, that isn't just good but different and textural and interesting in and of itself.

In that respect I've been very happy with Swells, and am planning to use it a bunch after this. Swells can play it straight, but the combination of self-generated modulation and great colouration options means Swells can draw attention, add unique character, and fill a role more than simply adding space. I've particularly liked pairing it with Jellymix, using Swells as a send and then using varying amounts of wet/dry across multiple instruments, creating a shared reverb environment that feels pretty glued. It's a great combo.

So do you need another reverb? Probably not. You don't need anything in hardware, honestly. But if you're looking for a hardware reverb that makes you think differently about time-based effects, and if you're looking for a reverb that sounds good in new ways, I think Swells is worth checking out.

Thanks for listening.

"Quad reverse sigmoid chaos module with CV inputs, sync controls and mixed outputs
https://www.nonlinearcircuits.com/mod...

single 1U version - https://www.nonlinearcircuits.com/mod..."

"This module is a set of 4 reverse sigmoid chaos circuits, running at different frequencies, there are pots to feed each section into another and influence, sync – sort of, the action. There are also CV inputs for each section which affect the reset or crossover timing, for the faster ones the results are obvious. For the slower ones, give it a few hours.

The reverse sigmoid circuits are similar in concept to the mackey-glass based design used in the NLC Frisson, but are greatly simplified to a bare minimum of parts. Simply an integrator, two all pass filters and a nonlinear stage with two feedback paths. The nice thing about them is you can use any capacitors you like, so long as all three are the same, and the circuit will work with no other mods required. The sections in this module use 1uF, 10uF, 2x 1000uF in series (so 500uF) and 2x 2200uF in series (so 1100uF).

They work quite differently to the Sloth chaos circuits, with a number of ripples or rolls between each attractor, also the three outputs track each other, the faster ones are delayed by a few seconds, the slower ones by minutes. The intent of having 4 different circuits running together with pots to get them to influence each other is to have a module that can create longer tracks with many different but related musical events happening and, of course, weird delayed CV effects. Think of a band where the members all do their own thing but every now and then the sounds and patterns connect and achieve structure, which slowly scatters and reforms in new ways.

Feel free to change the 1uF caps to a higher or lower value, similarly for the 10uF. Stack capacitors on top of each other to get 20uF, or use Tayda 22uF caps and stack them. See pictures on pg6 for info on which caps to change. Make sure the capacitors have at least a 25V rating or higher.

If you want to use larger values than 1000uF and 2200uF, make sure they will fit on the PCB and/or thru the panel holes (1000uF on PCB are 10mm diameter, 2200uF panel holes are 16.8mm)

There are also two difference rectifier circuits which output complex mixes of the individual chaos circuits."

1U REVERSE SIGMOID
DESCRIPTION/USAGE

6hp

This module is a reverse sigmoid chaos circuit; it can be built to run as a fast or slow CV source, or even as an audio/noise source. This is a single version of the four chaos circuits in the NLC How’s the Serenity module.

The reverse sigmoid circuits are similar in concept to the mackey-glass based design used in the NLC Frisson, but are greatly simplified to a bare minimum of parts. Simply an integrator, two all pass filters and a nonlinear stage with two feedback paths.

The nice thing about this design is you can use any capacitors you like, so long as all three are the same the circuit will work with no other mods required. The capacitors are marked ‘C’ on the PCB, 1uF is a good mid-range value to install, but 10uF, 22uF are good too albeit much slower. Lower values than 100nF get you into audio rate territory. Make sure the capacitors have at least a 25V rating or higher.

This works quite differently to the Sloth chaos circuits, with a number of ripples or rolls between each attractor, also the three outputs track each other, the faster versions are delayed by a few seconds, the slower ones by minutes.

The Input expects a positive CV, negative going CVs won’t hurt but will have no effect. The CV signal feeds into the first all-pass filter stage via 10k and a diode, this is different to the method used on How’s the Serenity. On slower builds, using 10uF caps, the effect of the CV will be washed out to some extent. It will still have an effect but not as noticeably as on the faster versions.

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!

New module! Dual Retro Vco

video upload by Radical Frequencies Modular

"Listen the new Radical Frequencies Dual Retro VCO playing an arpeggio , showing all waveforms and making Pulse with modulation and Hard Sync between the vcos . It goes through the RF Mixer and then to Diode Dream Vcf as it suits this oscillator perfectly! #eurorack #modularsynth #radicalfrequenciesmodular #dualretrovco #drvco #diodedreamvcf #analogsynth"

"Handmade Dual VCO of discrete core capable of internal FM cross modulations - Hard sync and Ring Modulator

• Analog discrete saw core oscillators with Saw, Pulse, Triangle and Ring Modulation wave outputs.The sound is warm and fat, emphasizing odd harmonics for this big retro sound. My purpose here is to approach the sound of classic synths from 70s, that we all loved.
• The SAW wave produces rich bass frequencies, sweet mids and smooth highs but overall, it is still well balanced across the full frequency range. The Triangle wave is almost perfect in shape with no buzzy hum sound. The pulse wave can produce that chorus-like phasing effect, when using an LFO to modulate the PWM input and does so in a very unique way, as it changes the phase of the signal as well.
• Two identical VCOs : VCO ALPHA and VCO BETA, with the ability of hard sync as each VCO syncs internally with the other. Using the attenuator knob for SYNC, you can go from zero to soft sync(11-12 o’clock) to hard sync when the knob is fully CW. For syncing you just need to turn CW, the sync knob of the VCO you want to be the slave. Don’t open both the sync knobs at the same time unless you want to make some weird sounds.
• There are external sync inputs for each VCO as well. External oscillators can be used as masters, just feed the output of the oscillator of your preference, into the sync input or either ALPHA or BETA. Just remember to feed a saw or a square wave, into the SYNC input. This is very important in order to sync the oscillator. A ramp wave it will not sync at all! (The RF DPVCO for example is a ramp out VCO and if you want to use it as master you must invert the signal first.)
• Both ALPHA and BETA track 5 octaves accurately, tempco resistors are attached to the tuning ICs CA3046 on both VCOs.
Separate voltage regulators for each oscillator can achieve the best sounding results without drift or bleed pitch, between VCOs.
• Both VCOs go from a relative fast LFO range with the coarse tuning knob fully CCW, up to high frequency oscillation.
• Octave Switches of 3 positions: 1 octave down - , zero , 1 octave up +, are available and make patching, fast and intuitive.
• There are internal normalisations for exponential as well as linear FM and both have independent EXP FM and LIN FM, attenuators.
• You can select the wave for the internal FM buss via the front panel switches .Options are Triangle and SAW. The internal FM wave, is independent per VCO as well.
• There are also internal normalisations for PWM, where each VCO modulates the pulse width, of the other and both use the triangle waveform.
• There is a PW offset, per VCO - negative phase pulse width at CCW to + positive phase at CW and 50-50 duty cycle square wave, in the middle of the knob.
• Ring Modulation section is a separate feature where X and Y inputs are internally connected with the VCOs as well. It has 2 inputs, X and Ψ and one out, RM. The inputs are internally connected to the internal FM buss switch of triangle - saw selector.
VCO ALPHA is internally connected into Ψ input and VCO BETA, into X input. You can feed the RM inputs any wave you desire from other VCOs as well .
• An external patch cable breaks the normalisation of all internal connections, via input jacks. (EXP FM, LIN FM, PWM, SYNC, X Ψ)

• Important note about tuning : The vcos need at least 30 minutes warm up before using it for good tracking. Also when you have to tune the vcos it’s better the octave switches to be in the middle position and all the fm and sync knobs must be closed (CCW)

• Large range of sounds with countless sweet spots - ultra stable tuning for FM sounds by using the FM and SYNC knobs simultaneously - fat basses, classic leads and drones. Feed the DRVCO into a good filter and you will enjoy it as it was meant to be! The VCF that I suggest is the RF Diode Dream VCF as it is a ladder filter and suits it perfectly! Of course any other filter of your taste can be used with great results."

EMS Synthi AKS Mk2, 1975 w/ Docs & 7" Record

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

via this Vemia listing

Click the auction link on top when you get there for additional listings.

"A superb and highly original EMS Synthi AKS Mk2, manufactured in 1975, in full working order and very nice cosmetic condition as shown in the photos. The aluminium front panel is in excellent shape and fitted with the original vernier dials, which have developed a lovely natural patina with age and use. The Spartanite briefcase is also in very good condition and retains the correct EMS London badge.
This is a genuine, unmodified example that retains its original character and components, something that is becoming increasingly difficult to find. It has clearly been a well-loved and carefully maintained instrument. I have owned it for the past 11 years, but it’s now time for it to move on to someone who will give it the use it deserves.

The Synthi A itself has been recently serviced by a professional vintage synth technician, and the KS sequencer was serviced four months ago by Robin Wood at EMS in Cornwall, ensuring everything is functioning exactly as it should.

Included with the synth: • Extra patch pins • Original Synthi–KS sequencer umbilical cable (excellent condition) • UK mains cable • Two keys for the Spartanite case so it can be locked — a great security feature… after all, no one would think of stealing a locked briefcase synth!

Also included is an excellent collection of original EMS documentation and ephemera, which is becoming increasingly difficult to find with surviving instruments: • Original EMS user manual, bound for protection • EMS 7' 33rpm demonstration record with cover • Original guarantee form (unused — unfortunately the manufacturer’s warranty has now expired!) • Several original EMS leaflets for the Synthi, VCS3 and Synthi 100 & Synthi Hi-Fli • Unused patch cards from 1975, in two different formats • Original 1975 EMS price list • An unbound copy of the Synthi Educational Handbook

Overall this is a beautifully preserved and highly original Synthi AKS Mk2, complete with period accessories and documentation — something that is becoming increasingly rare.

"We say...
A pre-owned Sequential Trigon-6 in very good condition. It comes with original packaging and power cable

Manufacturer's description
Experience the Power of Three Oscillators and a Ladder Filter with the Trigon-6 Module

The Sequential Trigon-6 desktop module delivers the same massive sound and hands-on sonic control as the Trigon-6 Keyboard. It features the same pure analog signal path with discrete oscillators and filters, and the same high-quality digital effects. It also has the same intuitive layout with full-sized knobs and switches that make it quick and easy to shape new sounds.

The Trigon-6 module sounds huge — just like the keyboard, because it is the same six voice polyphonic instrument, just in a smaller form factor. And if you want even more polyphony, you can use the poly chain feature to link any two Trigon-6s for a stunning twelve-voice synth!

A Sound That is Bold and Familiar

The Trigon-6 is Sequential’s polyphonic take on the classic, thick and creamy, 3-oscillator-plus-ladder-filter analog sound that defined the dawn of the synth era. It’s a sound that bridges genres and styles — now refined and redefined with Sequential’s own modern imprint.
