Elielson da Silva Gomes, researcher at INET-md and PhD candidate in the Department of Communication and Art at the University of Aveiro, Gilson Beck, researcher at École de la Cause Freudienne, Gilvano Dalagna, researcher at INET-md, and Alexsander Jorge Duarte, researcher at the Federal University of Pará, are the authors of the article “Revitalization Strategies for Electroacoustic Music: Dialogue between Pure Data, Affordances, and Performative Perception“, published open access in Revista Mosaico: processos criativos em música e em artes do som, v.2 (2025).
This article presents the results of an artistic research project centered on the exploration of the Pure Data software for the re-creation of Echo: for Trumpet, Tape and Delay, composed by Ross Harris in the 1970s for trumpet and live electronics. The project culminated in the recording of the work and in the systematization of the processes, which are organized in an exploratory model also described in this article. Both contributions of this study may inform new attempts at the technological updating of past works through the use of free resources, while also opening new directions for the development of an artistic voice in contexts of interaction between performer, instrument, and digital technologies.
