This project aims to improve outdated audio devices by pairing them with contemporary technologies. I propose the development of an analog multi-effect chain unit that combines different types of vintage components and modern microcontrollers. I seek to preserve the warmth and organic character of the analog sound and expand its capabilities with the flexibility and integrability of digital tools. The core element of the effect chain is an analog delay line which, if sampled in various sequences, produces different modulation effects. By design, the unit can be expanded with additional analog modules such as spring reverbs and tape delays that are chained in an interchangeable order and controlled by the same central microcontroller. The user interface is divided between a minimalist control panel located on the unit and a mobile app that allows for in-depth parameter adjustment.
