About cy83rd3ck

cy83rd3ck is an innovative open-source music instrument platform that runs directly in your browser, specifically optimized for Safari on iPhone. It offers a rich suite of features including 14 drum machines, 10 synth engines, a step sequencer, arpeggiator, multitrack recorder, sampler, and a virtual piano keyboard, all accessible without any installation. Built entirely from scratch using the Web Audio API, it avoids reliance on third-party audio libraries, ensuring a lightweight and efficient experience. The project aims to eventually extend into a physical hardware version featuring a Raspberry Pi Compute Module 4 (CM4), touchscreen interface, piano keys, and a compact form factor akin to an iPhone, blending digital and physical music creation. This tool is perfect for musicians, producers, and hobbyists seeking a portable, open-source solution for music production and experimentation directly in their browser, with an emphasis on accessibility and customization.
