INGA is a complex analog device combining a VCA and a 7-stage Wavefolder (based on
Serge type). I aimed to bring extensive functionality into a very compact 2HP module, with
complete manual and voltage control over all parameters.
Key Features:
- 7 Wavefolder Stages – Provides deep and rich harmonic transformation of the signal
- Folding Control – Precise depth control over the folding effect
- Stage Count Adjustment – Smoothly controls the number of active stages from 3 to 7, with
the ability to highlight the fundamental against added harmonics. The SHP parameter can
be modified both manually and via CV
- Signal Symmetry – Adjusts the symmetry balance of sound waves, enabling unique textural
possibilities. The SYM input can also serve as an additional input for mixing two signals and
processing them together with wave folding
- Dual Control – All parameters are adjustable both with knobs and CV, allowing flexible
integration into your system
The module is ideal for creating rich, textured sounds, adding multilayered harmonic
complexity.
INGA was created as the sister module to AGNI - use them together for total exterminatus! Link to AGNI - https://trianglecore.rocks/store/eurorack/p/agni-by-knob-technology-vca-and-multi-fx-unit

The SGR1806-20 is an analog synthesizer module designed for percussion sounds, lead/bass voices, and various noise generation. The module consists of two primary voice blocks:
1. Voice Block “V”:
- Features three unsynchronized triangle wave generators with single pitch control (1V/Oct) and internal EG.
- Generators 1 and 3 include the Spread function for altering frequencies relative to the second generator.
- Frequency modulation (FM) capability with a routing of 1osc -> 2osc -> 3osc -> 1osc.
- Feedback option with manual control influences the summing stage.
2. Voice Block “N”:
- Incorporates three noise generators for various noise textures, controlled manually and via CV.
Voice signals from both blocks are mixed using voltage control (V<MIX>N), offering manual and EG-based manipulation.
The module includes a 4-stage voltage-controlled Wavefolder for shaping and enriching signals, along with a Distortion/VC Mixer (DIST) node that allows parallel control over distortion and mixing parameters.
A voltage-controlled amplifier (VCA) facilitates amplitude modulation, while an EG D Envelope Generator generates control signals based on trigger input, with routing options to various module nodes.
With its versatile functionality, the SGR1806-20 module offers a range of sound design possibilities, from percussion synthesis to complex waveform manipulation.

Active Resonant Low Pass Gate
ARLPG is an active resonant LPG of the dream
This is an active resonant filter 12db\oct based on vactrols.
When creating it, I had a goal to make a compact and powerful tool for filtering signals. First thing - I tried to keep the bouncy sound of great-grandfather in the face 292, the second thing is to add a completely new resonance circuit, also driven by vactrols, in which the resonance would have a large amplitude at medium and low frequencies and decrease towards high frequencies, in order to avoid the frequent case of uneven auditory perception of a high level of resonance.
The REG (regeneration) knob was also added, which gives additional functions, at the minimum value of this knob, the filter does not color the signal, and works like a VCA, as well as reducing the attenuation of vactrols, at intermediate values it reduces low frequencies in the resonance circuit and allows you to finetune both the character of the resonance and the sound of the filter.
The filter has two operating modes HP and LP.
By voltage, you can control the cutoff frequency and resonance.
Like any good LPG, ARLPG is very friendly to gate signal management, since vactrols have their own natural release, which depends on the time and duration of exposure.
Device inputs and outputs
IN - audio signal input in ARLPG
OUT - audio signal output from ARLPG
Freq - CV input for filter cutoff frequency control
Res- CV input for filter resonance control

The AONX is a combined boolean logic device that's perfect for use in your Eurorack modular synthesizer setup. Consisting of logical elements including NAND, AND, NOR, XNOR, and NOT (analog), as well as a small passive signal splitter, the AONX allows you to compare voltages at its inputs and produce the result of a mathematical equation at the output.
With the ability to send signals to all inputs on the AB, A, and B lines, or connect signal paths independently depending on which connectors are used, the AONX is incredibly versatile and flexible. Whether you're looking to create complex modulation patterns or shape your audio signals, the AONX has you covered. So why wait? Add this powerful device to your setup today and start exploring the endless possibilities it offers.
Technical specifications
All inputs can receive voltages from -5V to + 10V, inversion is available over the entire input voltage range.
Logic inputs can receive voltages of 0 - + 5V, voltages above + 5V, and are limited by a protection mechanism up to 5.1V.
THR connectors are passively interconnected.
The INV connectors are passively interconnected.
The logic gates accept input and output voltages as logic levels high (1) and low (0). If the input voltage is lower than 2.5V, then it is read as a low level (0), if the input voltage is higher than 2.5V, then it is read as a high level (1).
The outputs of the logic gates can only have voltages of 0V at low state or 5V at high state.
Tables of functional states of logic elements, depending on the input levels at their inputs, are shown in the image below in the module structure.
The output of each logic element can be turned off (MUTE) and inverted (¯с), with this you can change the function of the original logic elements:
AND -> NOT INV = NAND
OR -> NOT INV = NOR
XOR -> NOT INV = XNOR
this way you can get all the variations of binary logic gates
Example: signal 1 goes to all inputs of logic elements through the THR AB connector, signal 2 is applied to input B of the (N)OR element, respectively, below the input B of the X(N)OR element there will also be signal 2, and signal 1 will be on these elements only at the A (N)OR inputs, and A X(N)OR.
Internal connections save the number of wires required in connectors to form a working patch.

DPLPG is a passive device that does not require power, resistor optocoupler based, or alternative name Vactrol. 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 / VCANoise transmission is dark -75db (+ - 10%) with an input signal Sine 1kHz + -5Vp-p in the mode withoutcutting the high frequencies.
Since this LPG is passive, the minimum voltage for opening is about 1.8V-2V.
The maximum CV source current required for maximum opening is 3mA, operating is less than 1mA.
Our LPG 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.
