public class MusicList
extends MusicJob

MusicList
A MusicList's children are InstrumentPlayable's. InstrumentPlayables implement public double play(double playTime, Composable parent,Instrument ins)
method which returns an updated playTime (such as playTime + parent.getTimeStretch * duration) A MusicList's Instrument gets handed to each of its children as it enumerates them over time.

Method Summary

Modifier and Type	Method	Description
void	add(InstrumentPlayable p)

InstrumentPlayable	get(int i)	return the InstrumentPlayable at position i
java.util.Vector	getChildren()
double	internalRepeat(double playTime)	Execute all elements in list with instrument.
static void	main(java.lang.String[] args)	Add some ad hoc InstrumentPlayable's to a MusicList and play it with the default (printing) Instrument.
double	start(double startTime)	open() Instrument and return startTime
double	stop(double stopTime)	close() Instrument and return stopTime
