matthiasm@774 30 * Extension of the NoteModel for more flexible note interaction.
matthiasm@774 31 * The original NoteModel rationale is given below, will need to be
matthiasm@774 32 * updated for FlexiNoteModel:
matthiasm@774 33 *
Chris@441 34 * Note type for use in a sparse model. All we mean by a "note" is
Chris@441 35 * something that has an onset time, a single value, a duration, and a
Chris@441 36 * level. Like other points, it can also have a label. With this
Chris@441 37 * point type, the model can be thought of as representing a simple
Chris@441 38 * MIDI-type piano roll, except that the y coordinates (values) do not
Chris@441 39 * have to be discrete integers.
