Functions
void	midi_note_get_global_start_pos (MidiNote *self, Position *pos)
	Gets the global Position of the MidiNote's start_pos.
MidiNote *	midi_note_new (RegionIdentifier *region_id, Position *start_pos, Position *end_pos, uint8_t val, uint8_t vel)
	Creates a new MidiNote.
void	midi_note_set_region_and_index (MidiNote *self, ZRegion *region, int idx)
	Sets the region the MidiNote belongs to.
void	midi_note_set_cache_val (MidiNote *self, const uint8_t val)
NONNULL PURE int	midi_note_is_equal (MidiNote *src, MidiNote *dest)
	Returns 1 if the MidiNotes match, 0 if not.
void	midi_note_get_val_as_string (const MidiNote *self, char *buf, PianoRollNoteNotation notation, const int use_markup)
	Gets the MIDI note's value as a string (eg "C#4").
void	midi_note_print (MidiNote *mn)
	For debugging.
void	midi_note_listen (MidiNote *mn, bool listen)
	Listen to the given MidiNote.
void	midi_note_shift_pitch (MidiNote *self, const int delta)
	Shifts MidiNote's position and/or value.
int	midi_note_hit (MidiNote *self, const signed_frame_t gframes)

void	midi_note_notes_to_events (MidiNote **midi_notes, int num_notes, Position *pos, MidiEvents *events)
	Converts an array of MIDI notes to MidiEvents.
void	midi_note_set_val (MidiNote *midi_note, const uint8_t val)
	Sends a note off if currently playing and sets the pitch of the MidiNote.
ZRegion *	midi_note_get_region (MidiNote *self)
