The use and implementation of software and digital-material controllers in conjunction with protocols indispensable for the process change the aesthetic experiences and capacities of musical and creative expression potentials in musical practices. What is first established as a constructed naturalness of individual music practices is challenged and disrupted by the digitality-specific multiplicity of the musical interface complex (hardware/software/protocol). The role of the empty-world hypothesis as a hidden agenda of these devices will be examined in more detail with the aid of a self-produced video documenting the use of the digital-material interface ROLI Seaboard by a musician playing in an “Arabic” idiom. Due to its dialectic framing character, the ROLI device will have to be described as a culturally expanding facilitator on the one hand and as a cultural capitalist artifact on the other.
