MIDI visualizer online
A good music visualization makes every note visible: a ball lands on a pad, a key lights up, a corner chimes. These games generate the level from the tune, so the motion follows the music exactly.
Load your own MIDI file in Melody Bounce or Roll Hopper, or pick one of the built-in public-domain classics and original songs, then record a vertical video.
Music and MIDI visualizers
Melody Bounce: A ball plays a song: every pad it hits sounds the next note, exactly on the beat. The level is generated from the tune, so short notes make tight zig-zags and rests make long flights. Pick a public-domain classic or an original, or load your own MIDI file.
Roll Hopper: A ball hops across the notes of a glowing piano roll and plays the song: every landing is the next note, exactly on the beat, and the key lights up on the keyboard. The roll is generated from the tune, so rests become long arcs and chords flash together.
Musical Path Premium: Turn music into a colourful journey along a flowing path: a ball travels the course and every bounce lands on the beat. Set the tempo and first beat, name and colour the cast, choose long flowing or short winding turns and record a portrait video. Use only music you have permission to use.
Chime Chamber: Nested polygons, one ball each, all sharing the same lap time: every corner is a note, so a 12-gon, hexagon, square and triangle build a hypnotic 12:6:4:3 polyrhythm that layers in, breaks down and builds back.
Pulse Bloom: Glowing balls bounce inside a neon rainbow ring while a red ×2 badge orbits it. Every ball that strikes the badge spawns another ball and fires a ring-wide burst; every bounce sprays sparks and plays the next note of an original tune.
Sort Spectrum: Watch sorting algorithms put a rainbow back together. Pick up to eight sorts from 47, one of 19 shapes, colours, element count and start order; every operation plays a note pitched by its value and a final sweep confirms the result.
How to turn a MIDI file into a video
Open Melody Bounce or Roll Hopper, choose the song selector and load your MIDI file (or pick a built-in tune). Set the tempo, instrument and look, press preview and check that the motion matches the music, then sign in and record. The video downloads as a vertical 9:16 MP4.
Use only music you have the rights to. The built-in classics are public-domain compositions played by the studio’s own instruments.
Which visualizer to pick
Melody Bounce: a ball bounces from pad to pad, one note per hit. Roll Hopper: a ball hops across a glowing piano roll and the keys light up. Musical Path: a ball travels a flowing course on the beat, with your own song. Chime Chamber builds polyrhythms from nested polygons, Pulse Bloom plays a generated melody on every bounce, and Sort Spectrum turns sorting algorithms into sound.
Questions
Can I upload my own MIDI file?
Yes, in Melody Bounce and Roll Hopper. Musical Path accepts an uploaded song instead.
Is the MIDI visualizer free?
You can preview without an account and record non-premium games on the Free plan with a watermark. Musical Path is premium: recording it needs Pro or Lifetime.
Does the ball really hit the notes on time?
Yes. The level is generated from the tune, so each hit is the next note at its exact time.
