  1665. Usage:
  1666. 1) In the program resource file setup a list of sync points.
  1667. 'asmp' refers to a sample offset into the audio file 'af'
  1668. which should match to the midi event index 'mid' in the
  1669. midi file 'mf'.
  1670. amSync :
  1671. [
  1672. { af:"af-16" asmp:34735276 mf:"mf-10" mid:350 }
  1673. { af:"af-16" asmp:71802194 mf:"mf-10" mid:787 }
  1674. ]
  1675. 2) Feed the 'fidx' output from a wave table loaded with 'af' into the 'asmp' input port of this amSync object.
  1676. Feed the 'id' output from the MIDI file player loaded with 'mf' into the 'mid' input port of this amSync object.
  1677. 3) Run the players.
  1678. 4) When the run is complete send any message to the 'sel' port of this amSync object.
  1679. The 'frm:' field of the printed output gives the difference in samples between
  1680. MIDI and audio sync points.
  1681. If the value is positive then the MIDI point is after the Audio point.
  1682. If the value is negative then the MIDI point is before the audio point.
