TY - Type of reference TI - Elements of technique and language for performing and composing with the digital musical instrument Karlax AU - Benjamin Lavastre AB - This article presents elements of technique and language for composing and performing with the Karlax digital musical instrument (DMI). Developed in the early 2010s, this interface is supported by an active community of composers/performers and an extensive repertoire. In this sense, the Karlax is an ideal candidate for a second phase of development with a DMI. Playing the Karlax or composing for this instrument requires a range of techniques and leads us to reconsider the place of instruments in the musical practices. To this end, the article offers a detailed examination of the interface, details different types of technique for composition and interpretation based on concrete examples, and proposes a philosophical and aesthetic framework, based on the main issues of sonic identity, the sound-gesture relationship, the interaction strategies and the perception.
