Electronics design

This page describes the high-level structure of the Shmøergh Moduleur electronics and how the different PCBs relate to each other.

The Moduleur is not a single circuit board, but a system built from multiple independent modules that together form a complete synthesizer.

Modular architecture

The Moduleur consists of individual functional modules such as oscillators, filters, envelopes, VCAs, utilities, and a digital Brain module.

Each module:

• implements one specific function
• has its own electronics
• can be designed, built, tested, and understood in isolation

At the same time, all modules are designed to fit together mechanically and electrically inside the Moduleur enclosure. Power distribution, signal levels, connectors, and mounting points are consistent across the system, allowing the modules to form a coherent instrument rather than a loose collection of boards.

Standalone modules, shared system

Although the modules are independent, they are designed with the Moduleur system in mind:

• Modules mount into a shared enclosure
• Power is distributed via a common bus
• Audio and control signals follow consistent conventions
• Modules can be rearranged, replaced, or omitted

This makes it possible to:

• build only selected modules
• expand or modify the system later
• reuse modules outside the Moduleur (e.g. in Eurorack contexts, where applicable)
