Fairfield Circuitry Board Member is a high-quality CV-to-Expression converter designed to act as the ultimate bridge between modular synthesizers and effects pedals. Unlike standard attenuators, the Board Member is specifically engineered to map Control Voltage (CV) onto the TRS expression standard. This tool is essential for artists looking to harness the complex modulation capabilities of Eurorack—such as sequencers and logic modules—and apply them directly to the expression inputs of their pedalboard.
Seamless CV and Expression Interfacing
The primary challenge when interfacing modular gear with pedals is the mismatch between voltage standards and physical connectors. Board Member solves this by converting CV signals (3.5mm input) into a format compatible with 1/4" TRS expression jacks. This allows for unprecedented control over delay times, filter cutoffs, or modulation rates on pedals from manufacturers like Strymon, Eventide, or Boss, effectively turning your entire pedalboard into an extension of your modular synthesizer.
Accurate Parameter Scaling and Offset
To ensure musical results, Board Member features precision controls for scaling the incoming voltage. This addresses the common issue of modulation "clipping" or overshooting the intended parameter range. By allowing you to dial in the exact sweep depth, it ensures that your LFOs and envelopes interact with your pedals in a predictable, expressive manner. As a passive device, it requires no power supply, ensuring a noise-free signal path and eliminating potential ground loop issues when connecting disparate power sources.
