Game jam background loops
Get a title, level or boss loop in minutes and drop the WAV straight into Unity, Godot or GameMaker.
Retro game music from four classic chip channels, ready for your DAW or game engine
Pick a style, key and tempo. The generator writes a looping chiptune with two pulse leads, a triangle bass and noise drums. Play it, roll new variations, then download the notes as MIDI or the sound as a loop-ready WAV.
Each part is assigned to a pulse, triangle or noise voice. Drums go to the noise channel; the highest parts take the pulse leads and the lowest part plays the triangle bass.

Have a song or recording instead?
Turn audio into editable MIDI first, then bring it back here to hear it in 8-bit.
Start from overworld, battle, dungeon, boss, victory or puzzle. Each style has its own chords, bass line, drum pattern and melody rhythm.
Pick the key, scale, BPM and 4, 8 or 16 bars. Switch channels on or off and change the pulse width for a thinner or rounder lead.
Every press of Generate rolls a new variation. The loop point lands on the bar line, so the preview repeats in time.
Download the WAV for a game or video, or the MIDI to re-voice the parts in your DAW. Open it in the editor to change single notes.
Get a title, level or boss loop in minutes and drop the WAV straight into Unity, Godot or GameMaker.
Use the MIDI as a starting point, then swap in your own chip plugins or layer modern drums in the DAW.
Upload a MIDI file and hear it played by pulse, triangle and noise voices instead of piano and strings.
Short victory and puzzle loops work as YouTube intros, stream alerts or menu sounds.
Yes. Generating, previewing and downloading MIDI or WAV are free and need no account or credits.
The loops are built from the rules and settings you choose, not copied from existing songs. PureMIDI does not claim ownership of what you generate, so you can use it in your own projects, including commercial ones.
Two pulse (square) channels carry the melody and harmony, a triangle channel plays the bass, and a noise channel plays the drums. This is the classic layout of 8-bit consoles.
Yes. Open the MIDI to 8-bit tab, choose a .mid file, and each part is mapped to a pulse, triangle or noise voice. You can preview it and download the result as WAV or as a re-voiced MIDI.
WAV contains the sound you hear here and is ready for a game engine or video editor. MIDI contains the notes, so you can change instruments, tempo and arrangement in a DAW.
Generated loops are exactly 4, 8 or 16 bars long and end on the bar line, and no note rings past the loop point, so they repeat in time without drifting or clicking. Any silence you hear at the seam is a rest in the music. MIDI files you convert keep their own length.
Yes. Choose Open in editor to move, delete or add notes in the PureMIDI piano roll, then export a new MIDI file.
