Bloop Maker
a little bloop machine that makes game music with you. no AI slop, no scraped songs. just notes.
runs offline · generates songs instantly · no account
Bloop Maker is a desktop app that writes original video game music for you. pick a vibe, press one button, and it builds you a whole multi-track song right then and there. no waiting, no loading bar. tweak it however you like, then export it as MIDI or audio and drop it into your project.
every song is built from real music theory, written in code. no AI. no samples. the music is yours, free and clear, for your game, your stream, your video, whatever cool thing you're making. music shouldn't be the scary part.
made for indie game devs, streamers, YouTubers, artists, and game jam folks who need their own background music right now, without copyright worries or anyone squinting and going "wait, is this AI?"
so what is it, really? think of it as a friend who hands you a song to start from, plus a little wall of buttons to reshape it: steer the mood, swing the groove, simplify a part, lock a hook you love, regenerate any channel. a quick spark when you've got ideas, and a gentle nudge when your brain's gone quiet.
No AI. No copyright headaches.
no machine learning, no training data, no songs scraped from anybody. Bloop Maker writes music with plain, fixed rules: chord progressions, melody logic, little motifs that come back around, drum patterns. use what it makes in commercial games, monetized videos, streams, personal projects. it's yours.
Not a toy. A tiny studio with buttons.
six independent channels, a full piano roll editor, 50+ melodic archetypes, 28 arpeggio styles, and six steering modes: bright, dark, cozy, punchy, cinematic, lo-fi. a colorful little composer for people building cool things.
Generate it. Poke it. Make it yours.
roll a song, then shape it: simplify a part, swing the groove, add some harmony, reverse a phrase, lock the bits you love and reroll the rest. keep nudging it until it sounds like your world.
Real files. Real useful.
export standard MIDI for FL Studio, Ableton, LMMS, Reaper, and the rest, or render to WAV with your own SoundFonts. make it, take it, finish it.

heads up: the desktop apps are unsigned, so Windows and macOS may warn about an unidentified developer. it's safe, just not code-signed (certificates cost money). on Windows, click "More info" then "Run anyway". on macOS, right-click the app and choose Open. Linux has no warning.
