Chiptune Tracker
A four-voice chip synth with a step grid in front of it: two pulse channels with selectable duty, a triangle, and a noise register. The synth is integer-only, so a song renders the same bytes here, in the test suite and from chiptune-cli on your own machine, and the WAV you export is that buffer; what your speakers actually play is resampled by the browser at its own rate and is deliberately not part of the claim.
Nothing here makes a sound until you ask it to. No audio starts before you press Enable audio, the level ramps in gently, and a limiter sits across the output. Headphones can still be loud, so start quiet.
Rendered when the site was built, by the same core the browser runs: the demo song Overworld, written out as the tracker grid that produces it. A browser cannot make a sound without JavaScript, so there is no audio on this page. The music is here as the grid, and chiptune-cli render song.json --out song.wav turns that same grid into the same bytes on your own machine.

| Field | Example | What it means |
|---|---|---|
| Note | C-4 | The note struck here, from C-0 up to B-7. Three dashes means this cell starts no new note and whatever was playing carries on. |
| Volume | c | One base-16 digit, 0 to f, so sixteen levels fit in one column. A dot means the cell says nothing about loudness; a 0 is the note off. |
| Effect | A47 | An arpeggio: the pitch cycles through the note, four semitones above it and seven above it, once per tick, six ticks to a row. Three dots means no effect. |
| Effect | S+3 | A slide: the pitch bends up three parts in 1024 on every tick, and keeps bending into the rows that follow until a new note lands. S-3 bends down. |
