Class BeatDivisionSchemeList

java.lang.Object
com.softsynth.jmsl.score.transcribe.BeatDivisionSchemeList
public class BeatDivisionSchemeList
extends java.lang.Object
This class holds a static Vector of BeatDivisionSchemes, which are valid for the entire piece under examination. A BeatDivisionScheme holds info on how to divide up a window up time (ex. triplet, with 2/3 members required to be found to qualify)

defaultSetup() sets up a BeatDivisionSchemeList of general purpose use. Code and explanation for a few BeatDivisionSchemes follow:
 
 // 16ths
 BeatDivisionScheme b = new BeatDivisionScheme();
 // covers a quarter note
 b.setTimeSpan(1.0);
 // could just be 1/4 of a quarter note
 b.setMinTimeSpan(0.25);
 // any number of sixteenths in beat span should be considered
 b.setMinRequired(0);
 // time span split into how many divisions by this
 b.setNumberOfDivisions(4);
 // Can this beat division scheme fill a beat independently of what beat it start on in the
 // measure?
 b.setConformToBeat(true);
 // add this beatDivisionScheme to the overall quantization strategy
 BeatDivisionSchemeList.addBeatDivisionScheme(b);
 
 // 8th note triplet
 b = new BeatDivisionScheme();
 b.setTimeSpan(1);
 b.setMinTimeSpan(b.getTimeSpan());
 // consider this even if only 2 of 3 triplets are present
 b.setMinRequired(2);
 b.setNumberOfDivisions(3);
 BeatDivisionSchemeList.addBeatDivisionScheme(b);
 
 // 16th quintuplet
 b = new BeatDivisionScheme();
 b.setTimeSpan(1);
 b.setMinTimeSpan(b.getTimeSpan());
 // consider this even if only 4 of 5 quintuplets are present
 b.setMinRequired(4);
 b.setNumberOfDivisions(5);
 BeatDivisionSchemeList.addBeatDivisionScheme(b);
