The advance of technology brings about modifications of style, performing techniques, music listening, and brings to us new relationships between creation, interpretation and perception. The aim of this article is to set out an approach to strategies of musical production for acoustic instruments and technological resources, describing different notions of interaction where the electroacoustic textural complexity coexists with the live processing of the instrumental source and where a goal is to work within the frame of an open and easy-to-carry-out performance structure which is friendly to the musicians, clear as a discourse and attractive to the audience.
