/**
 * Real-time Granulator sample
 * Made using JSliders.
 *
 * A more complex version of this instrument has been written using
 * MIDI control. It was used for the Poseidon - a Granular Texture Controlling Fish -
 * in the REV concert at the Brisbane Powerhouse. More information on this, and on
 * Granular Synthesis can be obtained at: http://zor.org/synthesis
 *
 * This file is used in conjunction with RTSliderGrainLine  
 *
 * Author: Timothy Opie
 * Latest Update: 24/06/2002
 * Designed to function with jMusic designed by
 * Andrew Sorensen and Andrew R. Brown
