Build a 16-step drum machine with a clickable grid for kick, snare, hi-hat, and clap, all sounds synthesized with the Web Audio API, plus play/stop and an adjustable BPM.
I'll create a standalone HTML file with a 16-step drum machine using the Web Audio API. The interface will include a grid for four drum sounds (kick, snare, hi-hat, clap), play/stop controls, and an adjustable BPM.

I've created a standalone 16-step drum machine with the following features: - A clickable grid for four drum sounds (kick, snare, hi-hat, and clap) - Full Web Audio API for synthesizing drum sounds - Play/stop controls with pause functionality - Adjustable BPM (60-180) with real-time updates - Visual feedback showing which step is currently playing - Active step highlighting and grid selection - Responsive design with a dark theme The drum machine uses synthesized sounds rather than audio files, with unique waveforms for each drum type: - Kick: Low-frequency sine wave with exponential decay - Snare: White noise burst with envelope - Hi-hat: High-frequency noise burst - Clap: Combination of noise and a slight pitch component All functionality is contained in a single HTML file with no external dependencies.
TAKE IT TO CODE
A single self-contained HTML file — copy it and open in any browser, or reuse the prompt with your own pi-agent run.
RUN
EVALUATION
Drum machine UI renders but grid cells appear empty/misaligned, only 'Kick' row column visible, layout seems broken with missing cell columns.

MEASUREMENTS
Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
