Shakmat Modular – Mod Medusa – Full DIY Kit

In a simplistic way, The Mod Medusa could be described as a Euclidean LFO : an “algorithmic” modulation source which produces variable period LFO signals synced to rhythmic patterns. Those patterns are generated by algorithms such as the  classic Euclidean one or from different algorithms adapted from the Shakmat White and Knight’s Gallop. The Mod Medusa has 4 outputs which generate 4 correlated LFOs, giving different “polyrhythms” according to the chosen mode.

Generated waveforms can easily be twisted using the symmetry and shape parameters which continuously morph the signal into different waveshapes. The range of  panel controls and assignable Gate and VCA Inputs turn the Mod Medusa into a strong performance tool. A very unique but cohesive approach to modulation which leads to instantaneous and original results!

Shakmat Modular – Aeolus Mixer – Full DIY Kit

Aeolus Mixer from Shakmat is a Eurorack quadraphonic mixer that brings together quadraphonic, stereo, and mono signals into one place. It’s perfect for installations, concerts, and 5.1 surround sound applications.

Aeolus Mixer features three sets of quadraphonic inputs and two sets of stereo inputs. The inputs are normalled together, allowing the quadraphonic section to handle stereo signals, and all sections accept mono signals. The second stereo input section has a cross switch, which changes how the two signals pass into the quadraphonic section.

Aeolus Mixer features four primary and two secondary outputs. Center is a mix of channels 1 and 2, otherwise known as the front channels, while the sum is a mix of all four channels. An included 5.1 switch compensates the gain on channels 1 and 2 to keep the volume equal between the front and rear. Four headers on the rear of the module provide a way to reduce the output gain by 6dB for each of the four primary outputs.

Eurorack has barely scratched the surface of the possibilities of quadraphonic spacializing. This module is a simple and elegant solution for panning and mixing signals in a four-axis space.

Shakmat Modular – Time Wizard – Full DIY Kit

The Shakmat Modular Time Wizard is an 8HP sextuple clock divider. The module features individual division control for all six outputs and there are different division options available depending on the divider channel being used. The outputs are split into two sections – A and B. Each section can receive its own separate clock input if desired, and there is also extra functionality associated with both sections:

Section A has the ability to multiply incoming clock signals (either x3 or x4) before the clock reaches the dividers. This allows you to easily dial in triplets or create very unusual clock ratio’s – for example: multiply by 4 and divide by 7 at the same time.

Section B has the option to receive it’s own master clock from RST input on the front panel or internally from divider B4. This allows you to create further complex divisions from the dividers below. There is also a jumper on the back of the module that allows outputs B5 and B6 to be switched from triggers to gates.

The module features an internal auto-reset option which comes from divider B6. This can be switched on to affect either just Section A or all of the outputs. There is also a manual reset input on the front panel. Finally there are some additional logic function options for divider A2: This output can be switched to provide the following functions : A2 AND B5 or A2 OR A3.

Shakmat Modular – Gemini’s Path – Full DIY Kit

Gemini’s Path is a 6HP dual VCA with internal modulation source and trigger extractor. The clever internal interconnection of the components makes Gemini’s Path a panorama and dynamics tool. The module reacts to the transients of incoming CV or audio signals, extracts trigger signals and activates the internal modulation source. A compressor or auto-panner, for example, can be patched in no time at all and can be quickly recalled using the memory function.

Gemini’s Path consists of several internally interconnected sections:

  • Two analog VCAs
  • Trigger Extractor consisting of rectifier, envelope follower and trigger detector. The sum of the incoming audio signals is fed into this section and the threshold potentiometer determines from which incoming voltage value a trigger is extracted.
  • The modulation source is triggered by the above section and generates envelopes, LFOs or random values.

Four modes are available:

-Expander: A release envelope is generated by each incoming trigger. In this case, the Time parameter controls the length of the release envelope and Depth controls the minimum amplitude or offset of the VCA.

-Pump: Compressor with adjustable depth (Depth) and release envelope (Time).

-LFO Pan: The LFO controls the panning of the audio signal and can be modulated in frequency (Time) and stereo spread (Depth). Triggers in this mode serve as soft sync for the LFO.

-Random Pan: Similar to the LFO Pan, the frequency is modulated by the Time parameter and the width of the panorama by the Depth parameter. Unlike the LFO Pan mode, this mode generates random values that move from one value to another. Trigger signals generate new random values.

Four alternative modes are also available:

-Hold Expander: Similar to the Expander mode with the difference that the VCAs are controlled by a hold function instead of a release envelope.

-Animated Pump: Like Pump mode but with a positive Saw-LFO

-Auto Pan: With each incoming trigger the position in the panorama is changed. Time controls the speed of the panning effect and Depth controls the width of the panorama.

-Granuliser: In this mode gates of random length are created which are influenced by the time parameter. The width of the panorama is controlled by the Depth parameter.

Since the module is DC-coupled, it is suitable for processing control signals as well as audio signals.

Features:

• Dual VCA

• Stereo / dual mono dynamic and panning processor

• Low noise and distortion That Corp dual VCA core

• Trigger detector section extracting gates & triggers from any audio / CV signal

• 4 dynamic modes : pump, animated pump, expander and holder

• 4 panning modes : LFO pan, random pan, auto-pan and granuliser

• Simple VCA mode giving direct access to level and panning

• Flexible control assignment : shared, dual or independent control with ability to load different modes for each channel

• Audio and external inputs DC coupled

• Unipolar CV inputs

• User replaceable firmware chip

• Digital jumper allowing to set dynamic modes sensible to triggers or gates

• Current state storing

• Skiff Friendly

• Width: 6HP

Shakmat Modular – Knight’s Gallop – Full DIY Kit

Math & Rhythm

Two outputs and five different rhythmic flavors multiply by a load of “algo-rhythmic” processing to result in a practically infinite number of polyrhythms. That’s the fundamental formula that produces the Knight’s Gallop principle : a dual trigger generator providing sequences according to tables and modes.

The source tables contain patterns such as the Euclidean polyrhythms, and the modes allow the user manipulate and mangle those patterns according to different algorithms. As the module has two outputs, it is a very powerful instrument to create diversified and instantaneous polyrhythms.

Features

• Dual Output Trigger Generator

• Variable length sequences (up to 16 steps)

• Length and Pulse amount potentiometers and CV inputs

• Shift + & shift – buttons allowing to shift the sequence forward and backward
