director: _play

  • cycle_pos, weight = metronome.*beat*()

  • IF meter-position is HEAVY (a *2* n the meter):
    • composer: choose_rhythm
      • voice:
        1. set_rhythm_grouping
        2. apply_overhanging_notes
  • composer: generate (main method - coroutine - that generates the next polyphonic step)
    • voices:
      • generate (the single voices generate their next step) the harmony is cumulatively created and later voices have to move their notes to comply with harmonic necessities
      • eventual “SLAVE” voice is made to follow another voice for some notes

    • note duration is registered for the each note

    • apply_scale()

    • embellish(state)

    • stream_analyzer() : decision if a caesura should take place (by setting <comment>-attribute to ‘caesura’)

    • drummer: generate

    • percussion_hub: send drum-frame to sound-engine

    • hub: send voices to sound-engine

    • notator: note_to_file

    • returns “caesura” or “normal”

    • new shuffle_delay

    • new speed

    • metronome: reset

    • composer

      • gateway.stop_all_notes

      • set_scale (choice(composer.SCALES_BY_FREQUENCY))

      • new_random_meter

      • IF automate pan:
        • each voice new pan
      • IF automate binaural diffs:
        • each voice new binaural diff
      • IF automate note duration prop:
        • each voice new note_duration_prop
      • IF automate transpose:
        • new transpose
      • IF automate wavetables
        • each voice new wavetable
