I represent a collection of individual notes at different pitches, volumes, and articulations. On request, I can select the best note to use for a given pitch, duration, and volume. I currently only support two volumes, loud and soft, and two articulations, normal and staccato, but I can easily be extended to include more. The main barrier to keeping more variations is simply the memory space (assuming my component notes are sampled sounds).

	allNotes Answer a collection containing of all the unique sampled sounds used by this instrument.
	chooseSamplesForPitch:from: From the given collection of LoopedSampledSounds, choose the best one to be pitch-shifted to produce the given pitch.
	memorySpace Answer the number of bytes required to store the samples for this instrument.
	midiKeyMapFor: Return a 128 element array that maps each MIDI key number to the sampled note from the given set with the closests pitch. A precise match isn't necessary because the selected note will be pitch shifted to play at the correct pitch.

	pruneNoteList:notesPerOctave: Return a pruned version of the given note list with only the given number of notes per octave. Assume the given notelist is in sorted order.
	pruneToNotesPerOctave: Prune all my keymaps to the given number of notes per octave.
	pruneToSingleNote: Fill all my keymaps with the given note.

	soundForMidiKey:dur:loudness: Answer an initialized sound object that generates a note for the given MIDI key (in the range 0..127), duration (in seconds), and loudness (in the range 0.0 to 1.0).
	soundForPitch:dur:loudness: Answer an initialized sound object that generates a note of the given pitch, duration, and loudness. Pitch may be a numeric pitch or a string pitch name such as 'c4'. Duration is in seconds and loudness is in the range 0.0 to 1.0.
