Notes: Really smart integration of macro controls for Eurorack, based on the original design by Emblematic Systems. Assign settings to eight CV outputs then morph with the crossfader or record movements to manage presets or set up complex real-time modulation. Can also operate as Catalyst Sequencer.

Supplier's Notes:
The Catalyst Controller is a macro controller with eight precision CV outputs and a responsive crossfader to morph between scenes. A scene is a snapshot of up to eight CV outputs, like a modular preset. Traverse a "pathway" composed of multiple scenes using the crossfader or an external CV signal, or immediately jump using the scene buttons. Record CV and slider movements, and play recordings back via a button or external trigger.

Each output has sub-millivolt precision and a maximum range of -5V to +10V. Channels have an adjustable morphing curve, can be quantized to common scales, restricted to a particular voltage range, or set to output gates.

Whether used as a CV preset manager, seamless transition generator, chord sequencer, CV recorder, or experimental CV playground, the Catalyst Controller puts control of your modular at your fingertips.

The Catalyst Controller can also turn into a Catalyst Sequencer! Hold down a special button combination to change between controller and sequencer modes. If you end up liking the Sequencer more, you can even remove the double-sided faceplate, flip it over, and re-install with the Sequencer artwork visible.

Based on the original Catalyst module from Emblematic Systems.

Based on the original Catalyst from Emblematic Systems

Pairs with: 4ms Catalyst Sequencer

Notes: The Catalyst Sequencer combines a traditional clocked step-sequencer with an unconventional phase-based sequencer to produce a new paradigm in sequencing. Eight precision CV sequencer channels can be simultaneously driven by a clock, a phase CV, or scrubbed manually with the crossfader.

Each of the eight channels has its own sequence length, quantizer, transposition, clock divider, randomization, voltage range (max -5V to +10V), and selectable CV (precise 16-bit resolution) or Gate mode.

Phase-based sequencing is an advanced form of sequencing where each step is selected by CV. The Catalyst Sequencer has a smooth, responsive crossfader that scrubs the sequence, playing it forward or backwards to track your motions. Patching in a CV signal will do the same: a ramp-up CV plays the sequence forwards, a ramp-down plays it backwards, a triangle plays it ping-pong, and complex waveforms generate new interesting rhythmic and melodic patterns.

The Catalyst Sequencer can also turn into a Catalyst Controller! Hold down a special button combination to change between sequencer and macro controller modes. If you end up liking the Controller more, you can even remove the double-sided faceplate, flip it over, and re-install with the Controller artwork visible.

A serious trigger sequencer for generating complex, multi-layered rhythms. Eight channels of Euclidean pattern generation meet probability, modulation and CV control for real depth and power.

Supplier's Notes:
Constellation is all about rhythm. It is an 8 channel pattern generator that works by combining multiple dense and sparse patterns to create long, complex and musically interesting trigger and gate rhythms. Constellation takes a "parametric" approach to rhythm - there is no explicit step sequencing on the module, rather the rhythms are defined by euclidean (and more) parameters that build the rhythm mathematically.

Constellation aims to evolve the concept of euclidean rhythms far beyond the useful but repetitive patterns we often think of when we hear the term "euclidean rhythm". This is accomplished by by combining up to 8 individual euclidean patterns of different lengths and density. Each pattern may provide only a small component of the final output, but together create immensely musical and varied rhythmic material over a very long time frame - up to 999 steps! If each of those steps are 1/16 note in length at 120 bpm, that's a full 2 minutes of explicitly defined, yet non repeating rhythmic material.

In addition, Constellation's parametric approach allows any of these parameters to be modulated with CV through one of 8 freely assignable CV inputs. CV modulation introduces further ability for Constellation's rhythmic output to vary over time. Paired with a Maestro or Navigators, hours of interesting morphing rhythms are possible without the need for tons of step programming or the uncontrollable chaos of a purely generative approach.

When writing music, rhythmic interest is often built through the combination of repeating and non repeating elements that work together to anchor the overall feel but also keep the ear free from boredom over the duration of the piece. Constellation provides a unique set of tools to accomplish this goal and achieve rhythms that are intentional, unexpected and exciting to use as the foundation of your compositions.

Notes: Two channel expander for Bartender

Mixer section

Each channel has the following:

Stereo or mono - Each channel can be treated as a stereo channel or a mono channel with two summed inputs.

CV inputs for both panning and level control

Two send buses - You can route each channel to one of two send buses. Each send bus is stereo. You can choose if you want the send to come before or after the level/panning controls.

Mute - The mute has both latching mute (up) and a momentary mute (down). The mute uses a capacitor to slow the turn off and on of the mute action. So it is mostly click-less, but you may find an occasional pop.

Cue bus - You can route each channel to the cue bus.

Expandable Mixer Series

Bartenders can be cascaded to create 8ch, 12ch, or 16ch mixer. The main level is what is sent the main level control can act as a group control.

Barbacks can be added to add 2ch to your mix. Barbacks can also be cascaded enabling up to a 16ch mixer configuration.

Send-VCA can be added for CV control of the level of the send.

DVCA, Cast Iron, Mingles, and USB-2CH can all be connected with Dupont cables (aka female to female breadboard cables) via pin headers on the back of the modules. Connecting the in and out pins will send/receive the audio into the next module.

Notes: Really clever stuff here. The Octaves VCO takes an additive approach, layering harmonics on top of a fundamental frequency to create complex tones. Control the six bands via CV to adjust the harmonic content.

Supplier's Notes:
A harsh and funky take of an additive Oscillator.

Pile up multiplications of your frequency to get a lo-fi-retro wall of squared sound!

You get six doubled frequency pulses, or octaves, with common PWM and volume control for each of them.

The output of each is cascaded to the next one, so you can either have one output with all frequencies or break the chain and get several sums and modulate each independently!

Features
Six bands, multiple of the base frequency.
Square wave oscillator with Octaves selector PWM control and sync.
Range control for Tune pot.
Volume CV control and individual output for each band
Cascaded summing outputs.

Module A-149-1 is the first module of the A-149-x range. In this group we present by popular request several functions of Don Buchla's "Source of Uncertainty 265/266" (SOU) modules that cannot be realized with existing A-100 modules. Many functions of Buchla's 265 and 266 SOU can be realized with existing A-100 modules. For details please refer to A-100 patch examples.

Module A-149-1 has available four different analogue random control voltages that are generated in different ways.

The "Quantized Random Voltages" section has available 2 CV outputs: "N+1 states" and "2N states". N is an integer number in the range 1...6 that can be adjusted with the manual control (Man N) and an external control voltage CVN with attenuator. Whenever the rising edge of the input clock signal (Clk In) appears a new random voltage is generated at the N+1 resp. 2N output. The N+1 output is capable to generate N+1 different voltage levels (or states), the 2N output up to 2N different states. If for example N is set to 4 the N+1 output generates up to 5, the 2N output 16 different states. The voltage steps of the 2N output are adjusted to 1/12 V in the factory. Consequently, exact semitones can be obtained in combination with a VCO. The voltage steps of the n+1 output are adjusted to 1.0 V in the factory corresponding to octave intervals in combination with a VCO. For each output a trimming potentiometer is available on the pc board that enables the user to select other voltage steps for the output in question.

Even the "Stored Random Voltages" section has 2 stepped CV outputs available: one with even voltage distribution of the max. 256 output states and second one with adjustable voltage distribution probability. The distribution probability is adjusted by a manual control (Man D) and an external control voltage CVD with attenuator. With the control set fully counter-clockwise most of the random voltages will be low magnitude but even medium and high magnitude voltages may appear but with smaller probability. As the control is turned to the right (or a positive control voltage appears at the CVD input) the distribution moves through medium to high magnitude voltage probability. The symbol at the lower jack socket shows this coherence graphically. The voltage range is 0...+5V for both outputs of the "Stored Random Voltages" section. For each output a trimming potentiometer is available on the pc board that enables the user to select another voltage range for the output in question.

The A-149-1 can be extended by 8 random digital voltages with the A-149-2 Digital Random Voltages module.

A unique analogue percussion module, based on principles from the legendary 909 twisted into new sonic territory. Capable of everything from classic kicks and snares to more experimental hits and complex VCO effects.

Supplier's Notes:
A machine is born

The Machine began as a quest to create a rich-sounding eurorack snare drum synthesis module to complement the existing Mutant Drums. The project quickly became too large and costly to justify the module being capable only of snare drum sounds. So, the decision was made to learn from the architecture of the TR-909's snare and kick circuits, in order to develop a module capable of generating multiple forms of analogue percussion, and various other effects.

Like the other Mutant Drums, the Machine has its roots in classic analogue percussion synthesis. Even though it can create totally alien sounds, it still has the capability to deliver those classic 909 house snares and kicks if you want them. There are no microcontrollers in the Machine. The signals and waveforms are all generated by discrete components and ICs, for a distinctly analogue sound, and user experience.

Features

Microcontroller-free analogue percussion synthesis engine
Unique Inverter Core oscillators form the MEMBRANE. Each analogue oscillator has three waveforms to select from
Capable of synthesizing everything from heavy-hitting bassdrums to classic 909-style snares and other complex timbres
Modular design gives the Machine many auxiliary purposes, great for modular sound design of many varieties, and not just percussion
The SNAPPY section is comprised of a voltage controlled noise oscillator, for modelling the noisy part of drum timbres
Both MEMBRANE and SNAPPY elements have an external input for replacing the built-in sound sources, opening up many avenues of possibility
13 control voltage and audio inputs, for a fully modular drum experience
7 audio and CV/gate outputs for maximum integration with other modules
Dedicated outputs for each WAVE and NOISE oscillator mean you can use the Machine as a complex VCO in your system, when not synthesizing percussion
Waveform scanning feature generates complex timbres from analog waveforms
The MEMBRANE's waveforms can be scanned through automatically by the wavescanner's voltage controlled clock generator, or an external clock or VCO can be used
SCAN FREQ CV forms a unique form of timbre control, making the Machine act like a complex oscillator at its WAVES output
The ENABLE input allows you to gate the wavescanner on and off with a CV or gate signal

Alia is a 10HP oscillator platform much like the Versio and Legio platforms. Launched in 2023 with a reboot of the beloved Basimilus Iteritas and Manis Iteritas, along with a new oscillator, Debel Iteritas, Noise Engineering is back with three more firmwares for the platform.

Separate hardware is available for each module, and a customer with any Alia module can try any firmware for free by going to the Noise Engineering Customer Portal and connecting with the included USB cable.

Cursus Iteritas Alia

Dynamically generated wavetable oscillator using orthogonal functions on a swappable oscillator platform

Cursus Iteritas Alia is Noise Engineering's take on a wavetable-inspired additive oscillator. Cursus creates sounds from a dynamically generated wavetable, then gives the user spectral controls to sculpt and modulate. Cursus has three different algorithms, based on different conceptualizations of frequency: Fourier, which uses sine waves; Daubechies, using wavelets; and Walsh mode, using the Walsh transform. All that math is hidden behind a set of friendly controls that produces an extremely wide variety of harmonic sounds, perfect for melodic sound design. Cursus has long been regarded as the gentlest Iteritas, but if you need some beef and extra low end, try mixing the suboscillator output into your patch.

CIA is available on Noise Engineering's 10HP Alia oscillator platform. Buy an Alia module and use the included USB cable to connect to the Noise Engineering Customer Portal and check out any other Alia firmware, free of charge, any time.

Notes: This module is a 12 ins and 12 outs precision buffered matrix.

It is conceived to be a semi-permanent matrix for medium to big systems, with white silkscreen labels to customize ins and outs names.

Every output has a rotary switch to select an input. This is not a mixer, you can make the same input go through several outputs but not several inputs go to the same output.

There's also a bicolor led next to every output for visual info of the signal that is going through it.

This module allows fast patch changes and easy rerouting signals, both audio and cv.

The last version has matte black & gold panel, and it's equipped with OPA4171 precision op-amps for the buffers.

Notes: VU meter for eurorack.

BLINKS is a VU meter for eurorack with 24 RGB leds per channel, function is pretty easy, it has 2 inputs, one for each led column (no output).

PATT button changes the led pattern ( 6 patterns to choose ).

SENS button changes the input sensitivity, cycling in 7 steps.

Long pressing the PATT button enters the color scheme selection.

Long pressing SENS button enters the brightness adjustment. Most probably you'll prefer the lowest setting.

The module has a 5v regulator in case you don't have 5v in you eurorack PSU. A jumper in the back select if the led board would be powered by the 5v rail or the internal regulator (which works with the +12v rail)

Up to 3 stereo signals can be connected to a buffered input using the rear headers.

Easy DIY with only a few components, the led board is already assembled.

5v not indispensable
+5v: 30 mA (on lowest brightness)
+12v: 4mA (or ~40mA if 5v rail is not used)

Notes: This is a 3HP version of the Douts module,

A breakout box for the direct outs of the TexMix. Valid for '4StereoChannels' and '4MonoChannels' version 1.5 & 1.6, for earlier channel expander versions some DIY would be required.

Each module has 8 outputs so it could have 2x '4MonoChannels' connected or 1x '4StereoChannels'.

DOUTS has 3 headers on the back, 2 of them are for 4 Mono Channels, the other one, labeled STEREO, is for 4 Stereo Channels.

Notes: This is the main module of the mixer and the only indispensable one, the only one that needs the eurorack power cable. It provides power to all the other modules and contains the summing circuit for all channels in every audio bus.

Notes: Remote extension module that allows to connect 16 signals (audio, CV, gate or whatever) between large or spread-out cases.

To avoid bleeding, signals are isolated with a ground line between them (both in the ribbon cable and the printed circuit).

The bundle consists in two XT modules and two ribbon cables (1, 1.5 or 2 meters depending on the option selected).

This is a passive module, it does not draw any current.
