A design study in minimal music machines.

This project is a browser-based digital keyboard inspired by the Casio PT-1, the small synth I grew up with. Built with HTML, CSS, and JavaScript (Tone.js), it captures the spirit of the original, from its simple one-octave layout to the playful retro interface.

It includes a mode switch (Off / Record / Play), tone selector (Piano, Fantasy, Violin, Flute), volume slider, and working keyboard controls. Users can play notes, record short melodies, and play them back.

While not yet a faithful recreation, it’s a work in progress that may evolve into a more complete digital PT-1 replica over time, blending retro design, creative coding, and nostalgia into one interactive project.
