97         * specific event in time where one or more voices were spawned at the same
98         * time and all those voices due to the same cause.

100         * For example when you press down and hold the sustain pedal, and then
101         * trigger the same note on the keyboard multiple times, for each key
102         * strokes a separate Note instance is created. Assuming you have a layered
103         * sound with 4 layers, then for each note that is triggered 4 voices will
104         * be spawned and assigned to the same Note object. By grouping those voices
105         * to one specific Note object, it allows to control the synthesis paramters
106         * of those layered voices simultaniously.
107         *
108         * If your instrument contains a real-time instrument script, then that
109         * script might also trigger additional voices programmatically (by
110         * calling the built-in script function play_note()). Each time the script
111         * calls play_note() a new Note instance is created and the script may then
112         * further control the voices of specific notes independently from each
113         * other. For example for each key stroke on your keyboard the instrument
114         * script might trigger 3 additional notes programmatically and assign a
115         * different tuning filter parameters for each one of the 3 notes
116         * independently.
