Norns modular

MOIRA is an open sound computer redesigned specifically for Eurorack systems.

It brings the core experience of the norns shield directly into your modular rack—scripts, sampling, synthesis, looping, algorithmic rhythms, MIDI control, and deep interaction with your Eurorack system—all without requiring additional desktop hardware, external interfaces, or complicated signal routing.

Instead of placing a Raspberry Pi on your desk, MOIRA places a sound computer directly inside your patch.

More importantly, MOIRA is not a fixed-function module. It is a platform that can continuously change its identity. Today it may be a sampler; tomorrow a granular processor. The next time you power it on, it could become a looper, an algorithmic drum machine, a MIDI processor, or an experimental sound environment.

Designed for Eurorack from the Ground Up

MOIRA is not simply a norns shield mounted behind a Eurorack panel.

The electrical environment inside a Eurorack system is significantly more demanding than that of a desktop device. Power rails, grounding schemes, audio levels, and module-to-module interactions all introduce challenges that require dedicated hardware design.

To ensure stable operation within a ±12V Eurorack system while maintaining clean power and audio performance, we completely re-engineered the module's power architecture.

During development, we redesigned the power system three separate times and produced five PCB revisions. Every iteration focused on the same goals:

Reducing system noise
Minimizing digital interference
Improving audio dynamic range
Optimizing signal integrity
Allowing Raspberry Pi processing, MIDI, digital interfaces, power conversion, and analog audio circuitry to coexist reliably within a single Eurorack module
