Pokey — Passive CV Performance Switch & Router (6HP) Pokey is a passive Eurorack module designed for expressive switching, routing, and mixing of two signals — whether audio or CV. At its core, Pokey is a hands-on performance tool: • Smooth manual crossfading between two inputs • Voltage-controlled switching and blending via CV or trigger • Works equally well with audio and control signals Because it’s fully passive, it requires no power and integrates easily into any system. What You Can Do With It • 🎛 Manual performance mixing — Blend two oscillators, textures, or modulation sources by hand. • ⚡ CV-controlled switching — Animate transitions using envelopes, LFOs, or triggers. • 🥁 Lo-fi “Lopez gate” style drum shaping — Use triggers to rhythmically open audio sources for percussive effects. • 🔀 Creative signal routing — Build evolving audio paths or modulation networks in compact systems. Specs • Width: 6HP • Passive design (no power required) • Skiff-friendly depth • Audio & CV compatible Pokey is simple in concept but powerful in practice — perfect for small performance systems and modular setups where space and immediacy matter.

XAOC Devices Kamieniec II Phaser and Allpass Expansion Review

video upload by Molten Music Technology




"KAMIENIEC II
ANALOG RESONANT PHASE ROTATOR

ALLPASS EXTENSION

MODELS OF 1977

Introducing two new Xaoc Devices products: Kamieniec II and its Allpass Expansion sidekick. Kamieniec II is an updated and extended revision of Kamieniec - our analog module inspired by a range of classic phaser effect units from the 1970s. We aimed to preserve the classic sound while making Kamieniec versatile enough to shine with any modular sound source. The newly released module shares the basic specifications with its predecessor: 4 and 6-stage outputs, built in triangle LFO (with a separate output in the true modular spirit), manual resonance control (up to extremely high values), and spicy feedback routing modes. On the other hand, Kamieniec II is a truly new beast with redesigned circuitry and new features, such as voltage control over resonance, a third feedback mode, and an LFO reset input. We have retained the chaining feature and we are glad to say Kamieniec II is fully compatible with the original Kamieniec, so you can easily mix and match both generations of the module should you develop a craving for more stages.

Want even more stages without sacrificing precious HP in your case? We've got you covered. Enter the Allpass Expansion - an optional circuit board installed at the back of Kamieniec II. It adds up to 16 sweepable stages for a total of 22 (!), making Kamieniec II one of the most multidimensional and versatile analog phasers available in Eurorack.

Oh, and one last thing - Kamieniec II is 10HP.

Crazy Chicken Modular SHRIMPY filter musical demonstration

video upload by Fedir Tkachov Music

"Musical exploration of new eurorack filter by Crazy Chicken Modular - SHRIMPY."

Shrimpy is a fully analog multimode voltage-controlled filter with three simultaneous audio outputs: low-pass, band-pass, and high-pass. It was designed with a strong focus on character rather than neutrality.

The resonance is voiced to emphasize midrange frequencies, giving the filter a present, expressive tone that cuts through a mix. At higher settings, it becomes vivid and assertive without collapsing into thinness.

At the heart of Shrimpy lies an unusual distortion chain integrated directly into the filter core. This distortion adds a pleasant crunch, enriching the sound. When pushed further, it can turn glitchy and rustling, introducing rough textures and unstable edges that make the filter feel alive. It should be noted that the distortion sound characteristics will depend on the Shrimpy settings and the input signal, since distortion occurs in the filter core itself, rather than at its input or output.

All parameters are fully voltage-controllable:
Cutoff frequency (with and without attenuator)
Resonance
Distortion amount

This makes Shrimpy a flexible yet opinionated sound processing tool, well suited for experimental patches, aggressive basses, textured leads, drones, and evolving soundscapes."

The Ensoniq ESQ-1 is a 61-key, velocity sensitive, eight-note polyphonic and multitimbral synthesizer released by Ensoniq in 1985. It was marketed as a "digital wave synthesizer" but is actually an early music workstation. Although its voice generation is typically subtrative in much the same fashion as most analog synthesizer that preceded it, its oscillators are neither voltage nor digitally controlled, but true digital oscillators, provided by a custom Ensoniq wavetable chip. The signal path includes analog resonant low-pass filters and an analog amplifier.

NO CV INPUT? NO PROBLEM | ADDAC System - ADDAC320 Servo Control

video upload by DANIELE

"The ADDAC320 Servo Control by ADDAC System, a module that converts incoming CV into physical movement, allowing you to automate any knob that doesn’t have a CV input by mechanically turning it!"

0:00 Intro
0:22 How to set it up
1:30 Minimum and Maximum angle
1:48 Patch example

"At ADDAC we always admired the geniality of Neil Young’s Whizzer, way ahead of it’s time, a great example how great ingenuity and engineering can come together to make something great. Inspired by it’s motor controlled method we created a 4HP solution to control any knob that doesn’t have a CV input, while also possible to use for other gear as well (within certain distance constraints).

We use a Servo motor which is a specific type of motor that can be digitally controlled to go to a precise angle. This motor is controlled by a microcontroller that also receives an incoming CV voltage from 0 to +5v and lineary converts this voltage range to the 270 degree Servo motor range.

Using a spring wire and metal couplers the motor shaft is then attached to the target knob to be controlled which will turn as the Servo turns.

Two other knobs [MAXIMUM ANGLE] & [MINIMUM ANGLE] further allow to control the “sweet spot” of the target knob, setting a smaller Servo range.

Raising the [MIN ANGLE] knob above the [MAX ANGLE] knob inverts the Servo range.

We can't stress enough how important it is to read the whole User's Guide thoroughly for this one!"

Classic Analog Polyphonic Synthesizers from the 1970s and 1980s

In this episode of RetroSound Studio Tour, I explore the sound, design, and history of legendary analog polyphonic synthesizers from the golden era of electronic music. These vintage poly synths defined the lush pads, warm brass sounds, and cinematic textures heard in synth-pop, progressive rock, disco, film scores, and early electronic music.

This studio tour focuses on true analog polyphonic instruments featuring multiple voices, voltage-controlled oscillators , classic analog filters , and rich modulation systems. Unlike monophonic synths, polyphonic synthesizers allow full chords and layered harmonic textures — making them essential in 1970s and 1980s music production.

Red Synton Syrinx Audio Demo

video upload by Edwin Kiddo

"Audio demo of my Synton Syrinx. This one has been serviced and the power input changed from 220 to 110V.

The Syrinx uses seven Curtis chips for its VCO's, VCF's and envelopes. It has two analog VCO's, a sub-oscillator and three flexible voltage-controlled filters. You can switch between the three filters for either a 24 dB lowpass, or two bandpass filters, and they can be patched in four different ways (series/parallel). Additionally the Syrinx has two LFO's, FM, PWM, osc-sync, 2 ADSR envelopes, ring modulation, portamento and a cool touch-pad that can control various parameters from pitch-bending to the LFO rate. The Syrinx's Mixer section lets you adjust levels for each VCO and the sub-osc as well as the Noise Generator and Ring Modulator. Unfortunately, being released around 1983, the Syrinx just missed out on MIDI and patch memory options.

Polyphony - Monophonic
Oscillators - 2 VCO's (tri, saw, square, PWM) plus 1 sub-oscillator, ring modulation and noise gen.
LFO - 2
Filter - 2 Bandpass filters (Peak 1 & 2) and 1 Lowpass 24dB/oct filter. Individual cutoff and resonance controls, ADSR Envelope, Keyboard Tracking and LFO modulation
VCA - 2 ADSR filters (one can modulate the VCF)
Keyboard - 44-keys (3 1/2-octave, no velocity, low-note priority)
Arpeggiator - None
Sequencer - None
Memory - None
Control - CV / Gate (Moog type). Touch 'N Bend Pad.

"Here's a nice, restored ARP Omni 2... with MIDI!! This synthesizer has just been fully serviced by Synthchaser, the United States' top ARP specialist - recapped, new key bushings, new LED sliders, clean, fully functional, calibrated, in tune and sounding great. And best of all, this has been fitted with the Synthchaser MIDI Adapter! This keyboard is the sound of Joy Division and is all over The Cars' "Moving In Stereo", and many other late 70's/early 80's albums. It produces the lush Solina/String Ensemble sounds plus has a polyphonic synthesizer section with a voltage controlled filter, LFO, and ADSR, and a dedicated bass synthesizer section.

Excellent condition, with some marks on the right leather side panel. Includes a road case that needs new foam and to be aired out as it smells musty. See photos for condition. This synth was serviced by Synthchaser (the top ARP specialist) in February 2026. Work done included:

Synthchaser MIDI Adapter - Supports MIDI IN and THRU (only an "IN" jack has been fitted on this synthesizer). Configurable MIDI channel and starting key on your MIDI controller.

Synthchaser Precision LED slider upgrade. All 15 of the old original sliders have been replaced with new, smooth, high precision LED illuminated sliders (purple color--think Prince!). The difference in the way these sliders feel and perform compared to the originals is a huge improvement.

Power supply rebuilt - All tantalum and electrolytic capacitors in the power supply have been replaced, and high quality, high temperature 105 deg C capacitors have been used for the power supply filter capacitors.

All tantalum capacitors replaced - The tantalum capacitors in ARP synths are ticking time bombs. All of the over 100 tantalum capacitors in this synth, including the power supply and filter submodule, have been replaced with electrolytics to help provide stable operation for years to come.

Synthchaser 4075 Filter Enhancement Kit Installed - The ARP Omni uses the same 4075 filter submodule found in the Odyssey, Quadra, Avatar, and Pro DGX. This has been recapped, and enhanced to provide superior frequency response.

Keyboard rebuild - New key bushings installed, buss bar & key contacts cleaned and adjusted, keybed leveled, keys cleaned
