This channel is dedicated to educational content in modular synthesis, mathematics, and physics. All videos are original, non-commercial, and designed to foster curiosity, learning, and community engagement.
I'm a software developer and electronics hobbyist who has become fascinated with electronic music and modular synthesis. I develop the Sapphire modules for VCV Rack, which are all free and open source, and always will be. Sapphire's goal is to facilitate generative and ambient music, and to help create interesting sound effects in a deep stereo field. I love connecting and getting nerdy about synth stuff, so always feel free to reach out here or on the VCV Rack forum.
