Abstract

Audio plugins processing equipment that serve beginner
instrumentalists have limitations regarding of extension
for physical control and integration with other equipment,
limiting the execution and the creation performances. Opensource
projects allow their adaptation or extension by modifying
the code or by integrating components that comply with some
specification. Pedal Pi, a low-cost open-source DIY project,
enables the development of software components for producing
HMIs through a specified API. In this paper, components are
developed that allow the control of the Pedal Pi by means of
applications for mobile devices. For this, a bibliographic review
of open-source solutions for the embedded processing of audio
plugins is performed, an analysis of the extension points offered
by the Pedal Pi software architecture is realized, the control
components developed are presented and are discussed the results
and the contribution relationships among the open-source musical
projects.
