The surge of advanced microcontrollers allowing for real+time processing of audio has taken the DIYworld of instrument and effect builders by storm. This project utilizes the Daisy Seed barebone platform from Electrosmith to implement a high definition playable musical delay for dub mixing and live performance. An important aspect of the platform is the capability to execute C++ code with extremely low latency at 24-bit 96kHz audio quality, comparable to state of the art delays like the

... rary and widely used El Capistan by Strymon Engineering. A second aspect of the project seeks to replicate the specific character and playability of vintage delay Roland SDE-2500 - one of dub pioneer King Tubby's favourites. Finally, the project explores rapid prototyping of real-time audio effects and sound generation with Max and Gen by Cycling74 and the translation to executable and embeddable Daisy Seed code with the Max object, Oopsy by Electrosmith. Evaluation, design, and implementation was conducted alongside a series of qualitative interviews with avid music producers, sound engineers and live performers with expertise in delays, sound design, and dub mixing.
