BounceLoop

Everything a loop needs, nothing it doesn’t

Bounceloop is a focused tool: simulate, score, sound, export. Here is what is inside.

A simulation you can trust

Bounceloop runs its own physics at a fixed 120 steps per second. Nothing depends on how fast your computer is.

  • Continuous collision detection, so fast balls never slip through walls.
  • A seeded random generator: the same mode, settings and seed always replay the same loop.
  • Seek anywhere on the timeline; the engine replays from the start to land on the exact frame.
  • 20 modes, each with its own settings panel generated from its schema.

Every bounce is a note

Turn a loop into a tune. The ball plays the next note of your melody each time it hits something.

  • A piano roll for drawing notes, with import and export of standard MIDI files.
  • Pick which MIDI track drives the loop when a file has several.
  • Nine instruments you can swap while the loop keeps playing.
  • Upload an mp3 or wav as a backing track, with offset and volume.

Let Auto Find do the searching

Not every seed makes a great loop. Describe what you want and let background workers look.

  • Goals such as a finale near the end of your track, a target length or a number of hits.
  • Hundreds of seeds are tried in parallel without freezing the page.
  • The best runs appear as live thumbnails you can open in the studio.

Available on Creator Pro.

Export without screen recording

Video is rendered one frame at a time from the simulation, so a slow computer makes a slower export, not a worse one.

  • H.264 and AAC in an MP4, at 720p, 1080p or 4K and 30 or 60 fps.
  • 9:16, 1:1 and 16:9 frames, with a title overlay for the first seconds.
  • Audio is mixed separately and lined up to the first visible frame.
  • WebM fallback for browsers without WebCodecs.
