KOMA Elektronik Sensei Eurorack Sensor Module

video uploads by KOMA Elektronik

The Sensei Eurorack Sensor Module complements the Koma Elektronik Field Kit Sensor Pack from six years ago:

Making Music With Sensors | Koma Elektronik Field Kit Sensor Pack

video upload by HAINBACH

"I was doubtful whether sensors would be fun tools to create music with - beta-testing the Koma Elektronik Field Kit sensors taught me otherwise. They are ideal creative tools in that they make you think differently and far out of the box. Perfect for breaking writer's block or pure musical enjoyment."



Press release for the new Sensei module follows:

"Berlin-based synth makers KOMA Elektronik introduce Sensei, a new Eurorack module designed to connect your modular system with the world around you. Whether it's light, movement, heat, or touch, Sensei lets you patch your environment.

"Originally based on the Sensor Interface from the KOMA Field Kit, Sensei is a standalone Eurorack module built for artists, experimental musicians, and installation creators who want to go „beyond the knob“.

Two sensor inputs (one for continuous signals, one for triggers and switches) allow for expressive, non-traditional control over CV and gate signals.

From subtle environmental fluctuations like heat or wind to pulsing club energy fired by strobe lights, Sensei makes your surroundings part of the music.

Users can choose from KOMA's established lineup of Field Kit Sensors currently available:

- Light
- Temperature
- Sound
- Touch
- Movement (Accelerometer)
- A Micro Sequencer with three modes
- Softpotentiometer
- Ball Switch
- Button / Jack Input
or plug in their own Arduino / DIY sensors with standard three-pin connectors.

And even without sensors, Sensei offers creative functionality: it doubles as a re-triggerable saw/triangle envelope, voltage processor with gain and offset, or a simple CV source.

Key features:

2 sensor channels: one continuous, one switch/gate style
Built-in analog processing (offset & gain)
Re-triggerable envelope mode (saw & inverse saw, gate & inverse gate)
Works with KOMA and standard 3-pin sensors
Perfect for installations, generative patches & sound experiments

With Sensei, modular becomes tactile, responsive, and alive. Your modular just grew a few more senses!

KOMA is currently running an introductory sale on their Sensors that you should grab if you are interested!

CG-Products XR 22VCO, Delay 1022, Peak + Hold, sound.report (Short explanation + 15 Min sounds only)

video upload by The Green Man(TGM) + sound.report by Heiner Kruse

XR22 VCO FT
VCO with Ring Modulation Input and FSK (Frequency Shift Keying)

Amplitude Modulation (AM) Input
Ring modulation
CV controllable sine/triangle volume
Advanced waveform generation by AM
Rgb-LED for optical control
FSK (Frequency Shift Keying)
Pulse and ramp generation
Switching between two different frequency CVs
Advanced waveform generation by FSK
LFO-, Bass-, High- Mode
Switchable Sync-Mode (from Rev.6)

The XR22 VCO FT is a VCO with amplitude modulation option – which can be used for volume control, or ring modulation of the oscillator’s sine/triangle output. The AM-input signal is added to a DC-voltage adjustable by knob ‘Gain’ (between ca. +/-5V) and the sum voltage is being internally multiplied with the sinewave/trianglewave The result is an oscillator amplitude depending on the ‘Gain’-DC plus AM-input signal. The applied AM-input signal can be mixed to the VCO output signal (modulated or unmodulated) too – a kind of ‘dry/wet’ control with the mix provided on the sine/triangle output. With no AM-input, the XR22 VCO FT behaves like a normal sinewave/triangle VCO, then its volume is controlled by knob ‘Gain’. Whereas with the knob ‘Gain’ in center position, the oscillator tone is becoming almost muted, and the input signal on ‘AM in’ controls the amplitude of the wave completely; thus the VCO can be used as a ring modulator.

The FSK (frequency shift keying) option provides two internally switchable different oscillator frequencies F1 and F2; each controllable by the two big-sized knobs (and their respective fine-tuning knobs and CV inputs). Switching between F1 and F2 can be done manually or by a logic signal (e.g. a gate signal) applied on input ‘FSK in‘. Further, it is possible to use the XR22 VCO FT‘s squarewave output for FSK switching. This will result in ramp or sawtooth (on the sine/triangle output) and pulse (on the squarewave output) waveforms. The falling and rising edges of the of the sine/triangle signal and the duty-cycle of the squarewave output are independently adjustable, and/or controllable via CVs of F1 and F2.

Furthermore, there is a switch for linking F1 to F2. In this case, the ratio between F1 and F2 is remaining the same, independently from the frequency, and ensuring properly 1V/oct. CV tracking.

A switch allowes to enable ‘sync mode’: An applied trigger will restart the wave always at the same point, useful for synced LFO applications and more.

For optical control, the XR22VCO FT has a full-color LED for AM visualization and a 2-color LED for FSK control.

Hell Modular CS80 INSPIRED DUAL FILTER

video upload by Cornel Hecht

"The CS-80 is renowned for its rich, expressive sound, and its filters play a crucial role in that. Here are the key characteristics of the CS-80's filters:
Dual Filter Design Per Voice
This is a standout feature. Each of the CS-80's eight voices boasts two independent filters:
1. High-Pass Filter (HPF): With adjustable cutoff frequency and resonance.
2.Low-Pass Filter (LPF): Also with adjustable cutoff frequency and resonance.
These two filters can be used simultaneously, enabling unique band-pass effects and exceptionally flexible sound shaping. The cascading of these filters results in a very characteristic, mid-range-focused sound."

When modules grow limbs: ADDAC's Servo

video upload by Electrum Modular

"Checking out Servo, a unique new module from ADDAC Systems. It can turn knobs or trim pots on a modular, synth, pedal, mixer, or anything else that’s small and cylindrical and that lacks a cv input. Perfect for when your hands are busy doing other things, or for when you want slow LFO-style modulation, or for when you want super precise stepped adjustments.

More info and manual:
https://www.addacsystem.com/en/produc...

Latest Electrum Modular album:
https://smallchanges1.bandcamp.com/al..."

"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!

"Quick demo/review of the FM Radius by koma elektronik
RTFM: https://koma-elektronik.com/new/wp-co..."

"The FM RADIUS is a CV-tunable radio receiver capable of receiving radio broadcasts on the FM bands. It provides the user the ability to catch radio transmissions for further manipulation.

The CV Radio is capable of catching the strongest broadcasts without any external antennas but for better reception, an external antenna should be used.

Use it as a crazy oscillator, infinite sample generator or just listen to the news during your office break."

WORNG Electronics Quiver LFOs

video upload by WORNG Electronics

"Four analogue LFOs drive the modulation of Quiver, with cycle times varying from 33ms to over 35 minutes. They're controlled with a Rate macro and CV, and the three slowest LFOs each have an additional CV control for further control. This patch demonstrates the various LFO outputs by modulating the cutoff of a Parallax filter."

Quiver Analogue Modulation Toolkit

Quiver is a 100% analogue patch-programmable modulation powerhouse. Quiver’s 16 input, 18 output interface contains:
- Four triangle core LFOs with macro control, individual CV control, and cross
modulation
- Analogue wave folder/saw phase shifter
- Full wave rectifier
- Analogue noise source
- Voltage comparator
- Sample and Hold
- Analogue Min/Max
- A three input, six output Modulation Cube based on the acclaimed Vector Space
circuitry
‍
When left unpatched the different processors flow from one to the next with cleverly designed normalling, giving 18 modulation sources to use throughout your system.
‍
Quiver is the perfect quiver of essential modulation basics to get your modular system started, or to add a high quality, fully patchable, modulation workstation to your existing system.
‍
When designing Quiver we asked the question 'What collection of CV processors can greatly expand the capacity of every modular system?' and then carefully chose normalled connections and added four analogue LFOs to drive them. The result is like a mini modular system in itself, creating complex evolving modulation that never repeats, but is able to be quickly reconfigured with a patch cable or two.

Djupviks Spektrum // What is a 'Switch Capacitor Filter'?

video upload by Lesjamusic

"🎛️ Djupviks Spektrum: The Filter That Clocks Itself 🎛️

Spektrum isn’t just another Eurorack filter. It’s a switched capacitor stereo filter that uses your input signal as its clock, turning audio into rhythmic glitches, stutters, and pulsing textures you won’t find anywhere else.

In this video, we break down:
✅ What a switched capacitor filter actually is (in plain English)
✅ How Spektrum turns your audio into patterns and sequences
✅ The unique stereo behavior and control layout
✅ Patch examples to unleash Spektrum’s chaotic beauty

Spektrum reacts to everything you feed it — arpeggios become glitchy basslines, noise turns into crunchy percussion, and waveforms transform into evolving rhythmic patterns.

If you’re looking to add a truly unique, reactive, and chaotic filter to your rack, Spektrum might just be the perfect machine.

Spektrum is available to buy as a kit from Thonk in the UK and Europe, SynthCube and Modular Addict in the US. SynthCube will be stocking some pre-built versions soon too.
