Drop a .MOD and watch the sound

Those 90s tracker tunes almost no player opens any more — .MOD, .XM, .IT, .S3M and 40+ exotic cousins. Drop the file below and it plays instantly, with the oscilloscope shifting colour by frequency: green in the bass, amber in the mids, red up top.

Why almost nothing opens these files

A tracker module isn't recorded audio: it's a score plus the instruments, and the player has to build the music on the fly, channel by channel. That's how the demoscene and the Amiga and DOS games fit onto a floppy.

The maths here is done by libopenmpt, the same library behind OpenMPT, compiled to WebAssembly. It runs inside your tab — which is why nothing is uploaded anywhere, and why it keeps working if you go offline after loading the page.

No module at hand? The Mod Archive has kept tens of thousands of them, free, since 1996.

This page is one piece of a bigger player

The colour oscilloscope, the tracker engine and the stubbornness about playing formats nobody else plays all come from VPX, a Windows desktop player: around 70 formats in one program, a 10-band equaliser, and one oscilloscope per channel instead of a single shared one. An unapologetic heir of the DOS-era visual players.
