iReal Pro format and model

Sources

Application model and playback algorithm

  • iReal Pro sheets are made of rows of cells
  • Each cell can contain a chord and other music annotations such as barlines, time signature, repeats, etc.
  • A row contains exactly 16 cells and barlines can be placed on any cell - one cell does NOT correspond to one beat!
  • The iReal Pro sequencer generates a playback sequence and detects illegal input (e.g. too many chords in a bar)
