I've created an index.html file in the /workspace directory with placeholders for your CSS and JavaScript code. You can now add your styles and JavaScript logic for the 16-step drum machine with a clickable grid for kick, snare, hi-hat, and clap sounds, all synthesized with the Web Audio API, plus play/stop buttons and an adjustable BPM. The file is ready for you to edit.
