Hexinverter Electronique

Notes: Really neat stuff from Hexinverter. Designed with synth sounds and drum processing in mind, the Hot Glue is a unique twist on a four-channel mixer, helping to integrate effects and voltage-controlled distortion alongside built-in bus compression.

Supplier's Notes:
The Mutant Hot Glue is a versatile bus mixer for analogue effects chain design. The included analogue compressor offers series or parallel compression and a sidechain input, making it particularly well suited to drum processing. The voltage controlled distortion is based on ideas borrowed from the guitar pedals responsible for a lot of yesterday's acid style techno sounds, but improved over the guitar equivalents, and made specifically for synthesizer and drum processing. The distortion can be used in its default position, normalized to the effects send, or like every other part of the module, broken out and used elsewhere in your modular system.

Features

4 Channel Mixer with Effects Send

4 input channels, each with their own level and effects send control
Channel A mixer bypass switch and dedicated output for easy sidechain compression
Channel B is dual input, but shares level/send controls (for dual output modules, like the Mutant Hihats)
Channel C+D summed output
Main mixer output normalized to compressor input

Hi-Fidelity Analogue Compressor

Soft-knee compressor based on the same family of premium audio ICs used in some 500 Series studio gear
Dedicated threshold and compression ratio controls
Gain control dials in up to +40dB of compressor make-up gain
Compressor sidechain input for creating pumping effects
LED indicator actively displays the amount of compressor gain reduction

Voltage Controlled Analogue Distortion

A classic distortion topology reborn for modular analogue synthesizers and drum processing
In/Outputs are conveniently normalized to the module's send and return jacks
Blend control lets you adjust the mix of distorted and clean input signal
Fast responding CV input allows for complex modulation patterns and even modulating with audio signals

By default, the 4 channel mixer's output conveniently feeds into the compressor's input, giving access to easy New York style parallel compression by way of the compressor blend control. The dedicated output and mixer bypass switch for channel A allow you to use it as a sidechain source for the compressor. An effects send and return allow you to create complex effects routings within your modular system. With the number of excellent DSP and other effects modules on the market today, this makes it easy to combine modules to great effect, all within the eurorack modular domain.

Redesigned by Erica Synths in close collaboration with Hexinverter. Minor alterations were made in mechanical assembly and digital controls to address Erica synths manufacturing routines and chip shortages, but the analogue signal path is 100% identical to the original version.

In September 2022 Stacy Gaudreau - the founder of Hexinverter Electronique, announced closing down the operations. Following their announcement, Erica Synths in cooperation with Hexinverter Electronique saw a way for their incredible and truly unique music instruments to keep on inspiring musicians and finding a home in countless studios to come.
The effort and innovation incorporated in Hexinverter Electronique eurorack modules are far too great to prematurely become history. Erica Synths will take over the manufacturing, sales, and support of several Hexinverter Electronique modules. While retaining all functionality of Hexinverter Electronique modules, Erica Synths redesigned the hardware of modules and will provide support for reissue modules only.

Notes: 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
