How to use this tool

  1. Enter beats, bpm, hits a, hits b.
  2. Use consistent units shown beside each input. Run the calculation and review the assumptions below.

Try this example

{
  "beats": 4,
  "bpm": 120,
  "hits_a": 3,
  "hits_b": 4
}

Accuracy and scope

Both patterns start together and divide one shared cycle equally; no MIDI file or audible playback.
