Artists and composers such as Jordan Rudess and Amon Tobin have explored the potential of MPE, integrating intricate and expressive synthesized sounds into their compositions.

Gender and Synthesizers

The exploration of gender dynamics within the world of synthesizers and electronic music encompasses a wide range of experiences, achievements, and challenges faced by individuals across the gender spectrum.

Pioneering Women in Electronic Music

Historically, women have been pivotal in shaping the landscape of electronic music, often overcoming societal and industry barriers. Daphne Oram, co-founder of the BBC Radiophonic Workshop, pioneered techniques in synthesizer and radiophonic music. Similarly, Else Marie Pade, from Denmark, explored and created groundbreaking works in musique concrète and electronic music. Wendy Carlos, through her work such as “Switched-On Bach,” played an instrumental role in bringing synthesizers to the wider public, blending classical compositions with electronic innovations.

Women in Modular Synthesis

Despite the often male-dominated nature of the electronic music scene, women have been, and continue to be, at the forefront of innovating within the modular synthesis community. Kaitlyn Aurelia Smith has made significant waves with her explorative and organic approach to the Buchla modular system, and Erika from Ectomorph (an American techno group) has long been a proponent of modular and synthesized soundscapes.

Challenges and Progress

Women and non-binary individuals have historically faced numerous challenges within the electronic music scene, from lack of representation and recognition to disparities in opportunities and pay. The inception of initiatives like Female:Pressure, a global network of female, transgender, and non-binary artists in the fields of electronic music and digital arts, is essential in advocating for and spotlighting underrepresented voices within the community.

Gender and DIY Synth Building

The DIY synthesizer building scene has also seen an influx of diverse gender participation, with artists and engineers alike designing and creating their own electronic instruments. Liz Dobson of the Yorkshire Sound Women Network has engaged in empowering women and girls through technology and sound workshops, fostering an inclusive environment for learning and creating.
