A browser‑based chord pad for rapid prototyping of chord progressions. Built with Next.js 15, React 19, Tone.js, and Tailwind CSS 4. You can audition, record, and share harmonic ideas straight from the browser—no DAW required.

• Any Key / Five Modes – Transpose the factory "C" map to any diatonic key and switch between major, minor, dorian, mixolydian, and lydian scales.
• Responsive Chord Pad – All scale‑appropriate chords are auto‑laid out in a responsive grid (≈18 pads). Click a pad to play the chord.
• Poly Synth Engine – Tone.PolySynth → HPF → Limiter → Destination, 8 voices, triangle waveform.
• Tempo Control – Type a value or drag vertically (60‑240 BPM). Loop timing updates in real‑time.
• Record & Loop – Every pad trigger is captured; hit PLAY to loop the sequence at the current BPM.
• 16 Progression Presets – Classic pop, jazz, Andalusian, blues, etc. Choose from a modal or generate one at random.
• Share / Save – Progressions are encoded into the URL for quick sharing, and can be saved to localStorage.
• Dark, Mobile‑first UI – Tailwind CSS 4 theme, scales from phone to desktop.
