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