MAUDLIN: Interface for Random Walks and Beyond - Eurorack Module for Ubiquitous Music

This paper offers an expanded review of work presented at the ubimus 2025 conference, detailing the MAUDLIN Eurorack module inspired by the “drunk” object in Cycling 74’s Max/MSP. MAUDLIN introduces a novel interface for generating controlled randomness in ubiquitous music (ubimus) practices by leveraging an unconnected Analog to Digital Converter (ADC) pin as a natural entropy source to augment pseudo-random sequences constrained within user-defined
boundaries. Designed for modular synthesisers, the module integrates control voltage (CV) inputs, potentiometers, and an display for real-time interaction and feedback, aligning with ubimus principles of accessibility and creative flexibility. We detail the module’s design principles and the use of environmental (EMF) noise to seed and perturb randomisation, we also discuss the potential to enhance musical creativity through constrained random walk outputs. As an opensource hardware and software development, MAUDLIN aims to democratise access, fostering collaborative
innovation in the ubimus and Eurorack communities while serving as a potential platform for expanded applications in embedded technology contexts.
