// 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.
// If the value is negative then the MIDI point is before the audio point.
