EaganMatrix Module

Integrate the power of EaganMatrix Sound Technology into your Eurorack! The EaganMatrix Module is a full-featured EaganMatrix Sound Engine for Eurorack, and can be controlled by control voltages and/or Midi. This versatile module can act as a sound source, a sound processor, a CV source (via connection to an external Control Voltage Converter), a Midi source, or a customizable combination of all these capabilities.

The EaganMatrix Module provides a truly versatile framework for both studio and live performance. Flexibility is key, due to its audio inputs and outputs, integrated CV inputs, external CV outputs (via Control Voltage Converter), and robust implementation of MPE and MPE+ Midi.

A single EaganMatrix Preset can give completely different sonic results, depending on how it is patched into a particular Eurorack ecosystem. Hundreds of System Presets are included with the EaganMatrix Module. In addition, an external cross-platform (Mac and PC) Haken Editor may be connected to modify and customize the supplied EaganMatrix System Presets, or create completely new presets from scratch.

The EaganMatrix Sound Technology, originally created for the highly sensitive Continuum, is now available to you in a Eurorack module. The EaganMatrix Module will quickly become a 'goto' component in your modular sound design and sonic composition.

EaganMatrix Eurorack Module — E2x $799.00

• Price is for purchase direct from the Haken Store; free shipping within USA — International customers responsible for customs/import duties — European and Australian customers please purchase from sources on your continent (Schneidersladen in Berlin, Modular Square in Paris, KMR Audio in London, Found Sound in Melbourne, etc) .

Haken Audio’s EaganMatrix Module offers:

• Polyphony: Nominal 1, Maximum 8
  Direct CV note control is limited to 1 voice at a time, but higher polyphony avoids voice stealing when EaganMatrix presets have long decays, and higher polyphony is often useful for Midi input.

• 4 Per-note CV Inputs: W, X, Y, Z

  • Gate (W) — Triggers at 1V, with max range -10V to +10V

  • Pitch (X) — 1V per octave, with programmable offset for Middle C; useful input voltages are a subpart of -10V to +10V (depends on the programmable offset selected)

  • Timbre (Y) — Function depends on EaganMatrix preset; voltage range is normally 0V to 5V, but -5V to +5V can be useful when combined with a programmable offset

  • Loudness (Z) — normally 0V to 5V, but -5V to +5V can be useful when combined with a programmable offset

• 4 Global CV Inputs: i, ii, iii, iv
  Functionality depends on EaganMatrix preset; these CV affect all voices (notes from WXYZ and Midi); each global CV is normally 0V to 5V, but -5V to +5V can be useful when combined with a programmable offset

• 2 Analog Audio Inputs: Left and Right, or Mono

• 2 Analog Audio Outputs: Left and Right, or Mono Sum
  -12dB switch selects between Eurorack Level and Line Level

• Midi over USB
  Allows bidirectional MPE and MPE+ connection to other devices; allows connection to the Haken Editor for editing and archiving EaganMatrix presets (USB-A cable included with purchase)

• Universal 3.5mm Midi In (Type A, Type B, and TS)
  Allows connection to other Midi devices without need of computer or USB (adapter to 5-pin DIN Midi In included with purchase)

• Type B 3.5mm Midi Out
  Allows connection to other Midi devices without need of computer or USB (adapter to 5-pin DIN Midi Out included with purchase)

• i2c Port for Communication to the Control Voltage Converter
  (a switch selects between 3.5mm Midi Out and i2c functionality)

• 12 Switches, 1 Rotary, and LED Matrix
  A menu system allows stand-alone operation without need of computer, and provides monitoring for notes being played and CV input levels

EAGANMATRIX Sound technology

The EaganMatrix is a modular digital synthesizer invented by Edmund Eagan, utilizing a DSP engine designed by Lippold Haken. This is the same EaganMatrix Sound Technology internal to the Continuum Fingerboard, the ContinuuMini, and Expressive E’s Osmose keyboard. The EaganMatrix allows the user to finely craft their musical sound by digitally connecting audio and control modules via a patching matrix. The EaganMatrix Module contains a sophisticated digital modular patching world of its own, ready to interact with your other Eurorack modules to make musical results never before possible.

EaganMatrix presets are edited by using an external cross-platform editing program, the Haken Editor. The EaganMatrix takes advantage of the subtle and dramatic musical possibilities provided by CV signals as well as MPE and MPE+ Midi. The freedom of its internal matrix design and internal deep modulation structure allows for unprecedented integration with your patched CV inputs. It allows complex sound modulation to be assigned and mapped to the detail of your control voltages. The EaganMatrix has very deep synthesis technologies under the hood to create very unique sound experiences. Ed has worked with Lippold to create something unique in terms of the types of synthesis topologies that are combined in union. Subtractive Synthesis, Physical Modelling with Modal Filter Banks, FM, Spectral Sets with Micro Analysation, including Waveguide with Feedback and Feedback Delay Networks are all at work for you here. This complex union of synthesis is what makes the EaganMatrix a unique proposition in terms of digital sonic exploration and interaction within the analog world of Eurorack.

SEE HOW IT WORKS

This video is from SonicState, made during the wonderful Superbooth21:

The next video shows audio processing with the EaganMatrix Module. The video uses a single EaganMatrix sound-processing preset called “Colour Delay”. All timbre variations are a result of the Eurorack world interacting with this one “Colour Delay” preset.

The video uses a mBiraski kalimba (with pickup) as sound source. Within the EaganMatrix’s “Colour Delay” preset, the mBiraski audio source is captured, looped, sonically altered both destructively and non-destructively, and converted to stereo space through the application of morphable convolution body responses. The EaganMatrix module is the only module on the audio path between mBiraski and speakers.

The “Colour Delay” preset uses the EaganMatrix Module’s i, ii, iii, and iv CV inputs for Eurorack control of Time Offset, Tonal Colour, Delay Time, and Delay Feedback. All external timbre control is through these CV inputs from third party sources, documented in the signal flow diagram on the left of the video.
