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.\u003c\/p\u003e\n\u003ch2\u003e\u003cb\u003e\u003cstrong\u003eDesigned for Eurorack from the Ground Up\u003c\/strong\u003e\u003c\/b\u003e\u003c\/h2\u003e\n\u003cp\u003eMOIRA is not simply a norns shield mounted behind a Eurorack panel.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eTo ensure stable operation within a ±12V Eurorack system while maintaining clean power and audio performance, we completely re-engineered the module's power architecture.\u003c\/p\u003e\n\u003cp\u003eDuring development, we redesigned the power system three separate times and produced five PCB revisions.

Our goal was not simply to make it work, but to create a module that feels truly at home inside a Eurorack system and remains a valuable creative tool for years to come.\u003c\/p\u003e\n\u003ch2\u003e\u003cb\u003e\u003cstrong\u003eAudio Path Optimized for Modular Systems\u003c\/strong\u003e\u003c\/b\u003e\u003c\/h2\u003e\n\u003cp\u003eRather than connecting a standard desktop audio interface directly to Eurorack signals, MOIRA features dedicated analog input and output stages powered from the ±12V rails.\u003c\/p\u003e\n\u003cp\u003eBoth the input and output paths utilize custom analog op-amp circuitry with adjustable level controls, allowing precise gain matching across a wide variety of modular scenarios.\u003c\/p\u003e\n\u003cp\u003eWhether you're processing hot oscillator signals, drum voices, feedback networks, or routing processed audio back into filters, VCAs, mixers, and external effects chains, MOIRA integrates naturally into the voltage environment of a Eurorack system.\u003c\/p\u003e\n\u003cp\u003eThe audio path is intentionally mono, reflecting the signal-flow philosophy commonly used in modular synthesis, feedback patching, and live performance environments.\u003c\/p\u003e\n\u003cp\u003eDedicated audio activity LEDs on both the input and output provide immediate visual feedback, allowing signal flow to be seen as well as heard.\u003c\/p\u003e\n\u003ch2\u003e\u003cb\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/b\u003e\u003c\/h2\u003e\n\u003cp\u003ePower\u003c\/p\u003e\n\u003cp\u003e- Power Requirement: +12V 500mA, -12V 10mA\u003c\/p\u003e\n\u003cp\u003eMechanical\u003c\/p\u003e\n\u003cp\u003e- Width: 20HP\u003c\/p\u003e\n\u003cp\u003e- Panel: High-resolution UV-printed PCB panel\u003c\/p\u003e\n\u003cp\u003eAudio Input:\u003c\/p\u003e\n\u003cp\u003e- Mono\u003c\/p\u003e\n\u003cp\u003e- ±12V analog op-amp input stage\u003c\/p\u003e\n\u003cp\u003e- Adjustable input gain\u003c\/p\u003e\n\u003cp\u003eAudio Output:\u003c\/p\u003e\n\u003cp\u003e- Mono\u003c\/p\u003e\n\u003cp\u003e- ±12V analog op-amp output stage\u003c\/p\u003e\n\u003cp\u003e- Adjustable output level\u003c\/p\u003e\n\u003cp\u003eLevel Controls:\u003c\/p\u003e\n\u003cp\u003e- Independent input and output potentiometers\u003c\/p\u003e\n\u003cp\u003e- Optimized for Eurorack signal matching\u003c\/p\u003e\n\u003cp\u003eSignal Indicators:\u003c\/p\u003e\n\u003cp\u003e- Dedicated input and output LEDs\u003c\/p\u003e\n\u003cp\u003e- LEDs respond dynamically to incoming and outgoing audio signals\u003c\/p\u003e\n\u003cp\u003eMIDI\u003c\/p\u003e\n\u003cp\u003e- 3.5mm TRS MIDI In\u003c\/p\u003e\n\u003cp\u003e- Automatic Type A \/ Type B detection\u003c\/p\u003e\n\u003cp\u003e- 3.5mm TRS MIDI Out\u003c\/p\u003e\n\u003cp\u003e- Switchable Type A \/ Type B operation\u003c\/p\u003e\n\u003cp\u003eUSB\u003c\/p\u003e\n\u003cp\u003e- 3 × USB ports\u003c\/p\u003e\n\u003cp\u003eProcessing Platform\u003c\/p\u003e\n\u003cp\u003eCompatible with:\u003c\/p\u003e\n\u003cp\u003e- Raspberry Pi 3B\u003c\/p\u003e\n\u003cp\u003e- Raspberry Pi 4B\u003c\/p\u003e\n\u003cp\u003eStorage\u003c\/p\u003e\n\u003cp\u003e- Includes a pre-configured 32GB microSD card\u003c\/p\u003e\n\u003cp\u003e- Operating system and software are pre-installed\u003c\/p\u003e\n\u003cp\u003e- Ready to use immediately after inserting the card\u003c\/p\u003e\n\u003cp\u003eExpansion\u003c\/p\u003e\n\u003cp\u003e- Expansion header reserved for future CV-to-MIDI and MIDI-to-CV modules\u003c\/p\u003e\n\u003cp\u003e- Expansion modules currently under development\u003c\/p\u003e\n\u003cp\u003eCustomization\u003c\/p\u003e\n\u003cp\u003e- JLCEDA Pro panel design files provided\u003c\/p\u003e\n\u003cp\u003e- Users can customize and manufacture their own front panels\u003c\/p\u003e\n\u003cp\u003eAssembly\u003c\/p\u003e\n\u003cp\u003e- Compatible with user-supplied Raspberry Pi 3B or 4B\u003c\/p\u003e\n\u003cp\u003e- Self-assembly supported\u003c\/p\u003e\n\u003cp\u003e- Assembly tools and resources provided\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cb\u003e\u003cstrong\u003eAfter-Sales Policy:\u003c\/strong\u003e\u003c\/b\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eProducts are \u003cb\u003e\u003cstrong\u003enon-returnable\u003c\/strong\u003e\u003c\/b\u003e after purchase.\u003c\/li\u003e\n\u003cli\u003eFor any \u003cb\u003e\u003cstrong\u003enon-human-caused quality problems\u003c\/strong\u003e\u003c\/b\u003e within one year, we offer \u003cb\u003e\u003cstrong\u003efree replacement kits by mail\u003c\/strong\u003e\u003c\/b\u003e and \u003cb\u003e\u003cstrong\u003eremote technical assistance\u003c\/strong\u003e\u003c\/b\u003e.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cb\u003e\u003cstrong\u003eShipping Location \u0026amp;
