Within computer-based and live electronic music, the values of competition, power, control and innovation dominate. Women continue to be under-represented in technical roles across production, management and software development. To address this imbalance, I examine how feminist frameworks and values can be applied to challenging the biases that influence uneven gender distribution within music technology development. Focusing on live embodied composition and computing where performative and design roles intersect, I explore the work of women composers who design or co-create bespoke systems that feature the body, reimagining the norms of music technology development while exposing insights about gender, race and body types in the sound and music industries. Referencing the work of Laetitia Sonami and Lauren Sarah Hayes, I argue that their embodied design practices constitute a type of activism that promote the feminist values of human computer interaction (HCI), including collaboration, transparency and empathy, countering dominant audio equipment and software design values oriented towards precise, perfected and disposable designs created in a hierarchical fashion.
