Digital Envelope Generator

The idea behind the GMSN! Pure Modular is to provide people with the basic building blocks of modular synthesis. Each module in the range performs a simple function. This makes it very easy to learn the principles of subtractive synthesis, while providing extremely powerful tools to explore non-traditional forms of music and sound design.

The GMSN! Pure ADSR provides a CV envelope with controls over the attack, decay, sustain and release. The envelope is triggered by either a trigger or a gate.

● Control over Attack, Decay, Sustain and Release
● Trigger or Gate Input
● Led Indicator shows envelope level
● Provide a CV output to shape any pitch, tone, volume, etc
● Arduino Compatible Code
● Width: 8HP; Depth: 75mm
● Power: 30mA +12v; 4mA 12v

The module comes as both a Complete Module, or as a DIY kit.

Synth DIY

For people wanting to get their hands dirty with coding eurorack modules, the Pure ADSR provides the perfect development platform. The module is an Arduino Uno Shield and all coding can be done via the Arduino IDE. For those wanted to take the next step passed shields, the full kit comes with an ATMEGA328, the same chip as the Arduino so again all coding can be done with the IDE, but this time as a proper embedded solution.

The DIY option come in 4 variations:

Complete kit with all components required, including panel
PCB, panel and preflashed IC. You’ll need to provide your own components, except for the ATMEGA IC.
PCB and panel. You’ll need to provide your own components. Full BoM is in the Build Doc (coming soon).
PCB and components, with no panel. You’ll need to provide your own panel.
PCB and preflashed IC. You’ll need to provide your own panel and components, except for the ATMEGA IC.
PCB. You’ll need to provide your own components and panel.
The circuit board is laid out cleanly to make component population and soldering a breeze and the build documentation includes step by step instructions, as well as fault finding hints and tips.
