3xVCA is a trio of high quality VCAs.
An intuitive one-knob design acts as both an attenuator and gain control.
Features
100% Analog
Fast Linear Response
Clean Signal Path
Equally Suited to Audio or CV Signals
Interesting Details
One Knob To Rule Them All!
The single LEVEL knob acts as both an attenuator and gain control. Rotating left attenuates incoming CV enough to completely null the channel. Rotating right increases the gain until the input and output are at unity. This simple one knob design is very “playable” and encourages performative use.
Trio of Pairs
The VCAs are built of discrete transistor “long tailed pairs”. Rather than using a specialized IC, we developed the VCA core using nothing but matched transistors and precision 0.1% components. Does this matter to the sound? Not really, but we still think it's cool!

This passive module works as a 7 in 1 out mixer or as two smaller mixers. Any signals or voltages put into the inputs of the module will be mixed and output from the bottom out. When a jack is inserted into the middle out, this creates two separate mixers - So the top inputs are mixed and output from the middle out, while the lower inputs are mixed and output from the lower out.
As this is a passive module, it is not unity gain so expect a drop in level of all inputs as each extra signal is inputted. despite this, it is a useful module for mixing audio signals or summing control voltages where accuracy is not of importance.

– Analogue voltage controlled oscillator
– Built-in Self-Tuning function
– Manual Fine Tune
– 3-wave mixer: Square, Saw-tooth & Triangle
– Signal level LEDs
– Easy to control & use
The Duskwork Self-Tuning VCO III is designed & built for Eurorack systems, requiring an external +/-12v power supply as per the Eurorack standard. It is just 6HP in width, so it’s easy to fit into any system; from a small skiff to a studio wall.
It contains an in-built Self-Tuning circuit, so gone are the days of finding your tuner. Just hold down a C note on your 1v/oct keyboard and hit tune – wait for the green LED to light up again, and then it will be perfectly in tune. These days, many of us wish to de-tune our VCO’s, and that’s why this updated version of the VCO now has its own manual fine tune knob in addition to the Self-Tuning function.
Another useful feature of this VCO, is the in-built 3 wave mixer. You can mix the 3 waves to your preference; Triangle, Saw-Tooth & Square. Each wave has its own signal LED so that you can tell how loud each wave is at just a glance. There is just one audio output, so no need to keep moving cables if you wanted to change the oscillator source sound.

Botanical Name: Flora Vertalius
Common Name: Attenuverter, Manual Voltage Source, Mixer (when being chained)
Description
The Flora Vertalius is a common and slim specimen in the Eurorack garden, known for its unique ability to tame, invert, and offset signals. This hardy perennial thrives in a modular ecosystem, providing both aesthetic beauty and functional value. Especially it enjoys being with its family, other Flora Vertalius species.
Growth Requirements
Power Supply: +12V, -12V (standard Eurorack power)
Space Requirements: 2HP width, skiff-friendly
Cultivation and Care
Feeding (Signal Input):
The Flora Vertalius accepts a variety of signals through its INPUT jack (the top one), flourishing with both audio and CV signals.
You don’t have to feed Flora Vertalius, without food it becomes a Voltage Generator and can provide you with the constant voltage controlled by the slider. The toggle allows you to go to the negative voltage territory
Growth (Attenuation and Inversion):
The primary function of Flora Vertalius is controlled by the slider.
The switch shifts between the attenuation and inversion modes.
Chain Cultivation (Chaining Multiple Modules)
Interconnected Growth:
The Flora Vertalius can be linked with other modules of its family to create a continuous signal path.
Utilize the pins at the back of the module named OUT and IN to chain modules together using the provided cable.
OUT: Sends the processed signal to the next module.
IN: Receives the signal from the previous module.
This chaining allows for a seamless integration, ensuring that the signal is normalized across all connected Flora Vertalius, enriching your modular garden with expanded possibilities.
To “break” the chain, insert a jack cable to the OUT, this will stop the module from feeding the next in line.
The “parental” module’s signal is mixed with the child’s one. You can mix both audio and CV signals. This module is not a mixer per-se, but with your creativity it can function as one.
Keep in mind the polarity of the audio signal. The pins are marked, so you don’t mistake it
Mix it up with the Micro Mix, a dual passive mixer in 2hp that functions as both a 3-to-1 and a 6-to-1 passive mixer, allowing you to perform acts of minor sorcery in your modular system (or maybe outside with your Volca and Pocket Operator jam?).
Nothing knobs or buttons here to confuse you, plug in either audio, CV, clock or triggers, and get the mixed signal out. The best part? Since it's passive, there's no guarantee what you put in is exactly what you'll get out. Embrace the unpredictable world of passive mixing like they did in the 60s and 70s.
Go ahead, spend your money, you'll be very glad you did.

Phaser and delay in one module
Onboard LFO
Broad CV control
Two outputs, so can be connected to stereo equipment
Two modules in one project: a phase shifter of 4, 8 and 12 steps and an echo processor.
The phase shifter has input level control, rate, depth and feedback controls, two modulation modes (triangular and ramp) step selector, CV for depth,
Using a switch, the phase shifter can be used without the echo module.
The echo processor has input level, echo level controls, echo repetition and delay. All these controls have their own CV.
The module has two outputs. Output A, with the steps that we choose in the phase shifter, and output B, with 4 random steps output.
The outputs are simultaneous so it can be connected to stereo equipment creating a very complex and full envelope.
Sewastopol allows you to interface your modular system with the outside world in many ways. Actually, there are 3 submodules in one compact package. The lower section can be used as input and output audio interface and external effects adaptor, while the upper section is an innovative voltage extractor consisting of a versatile, very accurate envelope follower and comparator. Either section can be used independently.
FEATURES

DALPG the active version has a control circuit that removes the minimum voltage threshold and LPG work like VCA.
This device, without supplying voltage to the control input, almost does not pass the signal, when the control voltage is applied, it changes the amplitude and opens like a VCA amplifier, with a characteristic curve corresponding to the resistor optocoupler, which has a small signal release (LPG envelope), and the memory effect of a resistor optocoupler.
Technical specifications:
- Normally closed gate / VCA
- Noise transmission is dark -75db (+ - 10%) with an input signal Sine 1kHz + -5Vp-p in the mode without cutting the high frequencies.
- The maximum CV source current required for maximum opening is 3mA, operating is less than 1mA.
DALPG and DPLPG use matched pairs of opto-resistors and LEDs to provide excellent speed performance. The maximum frequency of distinguishable modulation of one signal by another signal is 10 kHz.
IMPORTANT
This is the updated version with the improved passive mode.
