About StepSeqPoly
StepSeqPoly Live Edition is an in-browser polymetric groovebox that merges a deep sequencing workshop with a high-performance live matrix.
It bridges the gap between hardware ergonomics and modern web technology, running entirely on the Web Audio API—no plugins required. This tool was born from a personal quest to create a lightweight, anytime-accessible performance environment that reflects the freedom of hardware-based live jamming.

About the Author
Hello, I’m Shurikat. I am a Belgian dawless live music entertainer and the creator of this project.
My journey into electronic music started with a deep love for hardware, particularly the Roland AIRA Compact series, which I showcase through live jams and tutorials on my YouTube channel. StepSeqPoly was born out of those moments when I didn't have my gear with me but needed to keep the creative flow alive. It’s the result of combining my passion for live performance with a journey into software project management and AI-assisted development.
