Your music. Your notes. Your painting.

How to play with an MP3 file

1. Open “upload mp3”. Choose it on the home screen, then select “choose file from my PC”. Pick an audio file saved on your device.
2. Use the automatic chart. The game analyzes your audio to build a chart: a sequence of notes to hit. Preparation time depends on the song and your device.
3. Set up your game. Start with 4 lanes and easy difficulty. You can adjust the note scroll speed separately.
4. Press play. Follow the notes to the hit line. The default 4-key layout is D F J K; you can change it in settings.

Your MP3 is processed on your device. The selected file is not sent to a server to generate its chart. You do not need to install ColoRythm or create an account to play.

Automatic, imported or handmade charts

Automatic charts are a quick way to try your music. Rhythm detection can produce different results depending on the mix and instruments; it is not the same as a manually reviewed chart.

To choose exactly where notes appear, open create → chart editor. You can record by tapping in real time or edit notes individually. You can also import .crchart, .json, .sm or .ssc files with their matching audio. An imported chart defines its own difficulty and lane count.

Other games may use note types that ColoRythm does not reproduce in the same way. When importing StepMania files, holds become taps at their starting points. Review the result before playing.

To try the game immediately, open the song catalog. Available prebuilt charts load directly, avoiding another chart-generation step.

Every successful hit also paints

Play on a blank canvas or load an image to rebuild it with splashes. Colors appear as you hit the notes. After the song, you can keep painting, sign your artwork and export it as an image.

Settings let you choose whether all successful hits or only perfects add paint. To make the notes easier to read, adjust the track opacity and try the Splash, Chromatic pulse or Simple hit animations.
