abstract = {This thesis investigates continuous interaction as a design principle for Artificial Intelligence (AI)-powered music creativity support tools. Discrete text prompting, the de facto standard for current generative AI systems, can limit musicians’ sense of artistic agency and creative ownership. Continuous interaction instead can enable fine-grained, real-time control over the generative process, helping musicians retain a sense of authorship over the generated output.



This thesis presents three studies that together examine how continuous interaction, integrated into real-time interfaces, can better support musicians’ creative workflows. First, I derived low-dimensional latent representations from a Variational Autoencoder with an intentionally small latent space, integrated them into a real-time GUI, and evaluated them in a mixed-methods study with both novice and experienced synthesizer users (n = 18). Second, I interviewed experienced musicians (n = 10) about their hesitations toward generative AI; their concerns centered on a lack of compelling tools and workflows, further motivating continuous interaction as a design preference. Finally, I developed a framework for Aging Digital Musical Instruments (AgingDMIs), a novel class of instruments that adapt to a user’s play style over time. I then implemented a hardware prototype instantiating one point in the AgingDMI design space, and evaluated it longitudinally with experienced musicians (n= 4) for twelve recurring sessions over several weeks.



The findings presented in this thesis suggest that integrating continuous interaction into generative AI-powered creativity support tools increases musicians’ artistic agency and creative ownership and fits better within their existing creative workflows. I further contribute a validated

design framework for AgingDMIs, a novel class of adaptive and personalized digital musical instruments, and a hardware prototype that together demonstrate the principles of that framework in practice.},
