Detailed Description

A Region containing MIDI events.

MidiRegion represents a region in the timeline that holds MIDI note and controller data. It is specific to instrument/MIDI tracks and can be constructed from a MIDI file or a chord descriptor.

Definition at line 37 of file midi_region.h.

Member Typedef Documentation

◆ ChordDescriptor

◆ add_events()

void MidiRegion::add_events	(	dsp::MidiEventVector &	events,
		const Position *	start,
		const Position *	end,
		bool	add_region_start,
		bool	full ) const

Adds the contents of the region converted into events.

Parameters

add_region_start	Add the region start offset to the positions.
export_full	Traverse loops and export the MIDI file as it would be played inside Zrythm. If this is 0, only the original region (from true start to true end) is exported.
start	Events before this (global) position will be skipped.
end	Events after this (global) position will be skipped.

◆ export_to_midi_file()

void MidiRegion::export_to_midi_file	(	const std::string &	full_path,
		int	midi_version,
		bool	export_full ) const

Exports the Region to a specified MIDI file.

Parameters

full_path	Absolute path to the MIDI file.
export_full	Traverse loops and export the MIDI file as it would be played inside Zrythm. If this is 0, only the original region (from true start to true end) is exported.

◆ get_note_positions_in_export()

void MidiRegion::get_note_positions_in_export	(	Position *	start_pos,
		Position *	end_pos,
		int	repeat_index ) const

Set positions to the exact values in the export region as it is played inside Zrythm.

Parameters

[in,out]	start_pos	start position of the event
[in,out]	end_pos	end position of the event
	repeat_index	repetition counter for loop offset

◆ get_velocities_in_range()

void MidiRegion::get_velocities_in_range	(	const Position *	start_pos,
		const Position *	end_pos,

		bool	inside )

Fills in the array with all the velocities in the project that are within or outside the range given.

Parameters

inside Whether to find velocities inside the range (true) or outside (false).

◆ init_after_cloning()

void MidiRegion::init_after_cloning	(	const MidiRegion &	other,
		ObjectCloneType	clone_type )

overridevirtual

Initializes the cloned object.

Note: Only final classes should implement this.

Exceptions

ZrythmException If the object could not be cloned.

Implements ICloneable< MidiRegion >.

◆ is_note_export_start_pos_in_full_region()

bool MidiRegion::is_note_export_start_pos_in_full_region ( Position start_pos ) const

Returns if the given positions are in a given region as it is played inside Zrythm.

Parameters

offset_in_ticks Offset value if note is repeated inside a loop

◆ pop_unended_note()

MidiNote * MidiRegion::pop_unended_note ( int pitch )

Returns the midi note with the given pitch from the unended notes.

Used when recording.

Parameters

pitch The pitch. If -1, it returns any unended note. This is useful when the loop point is met and we want to end them all.

◆ print_midi_notes()

void MidiRegion::print_midi_notes ( ) const

Prints the MidiNotes in the Region.

Used for debugging.

◆ start_unended_note()

void MidiRegion::start_unended_note	(	Position *	start_pos,
		Position *	end_pos,
		int	pitch,
		int	vel,
		bool	pub_events )

Starts an unended note with the given pitch and velocity and adds it to midi_notes_.

Parameters

end_pos If this is nullptr, it will be set to 1 tick after the start_pos.

◆ validate()

bool MidiRegion::validate	(	bool	is_project,
		dsp::FramesPerTick	frames_per_tick ) const

overridevirtual

Validates the arranger object.

Parameters

frames_per_tick Frames per tick used when validating audio regions. Passing 0 will use the value from the current engine.

Returns: Whether valid.

Must only be implemented by final objects.

Implements ArrangerObject.

◆ write_to_midi_file()

void MidiRegion::write_to_midi_file	(	MIDI_FILE *	mf,
		bool	add_region_start,
		bool	export_full ) const

Exports the Region to an existing MIDI file instance.

This must only be called when exporting single regions.

Parameters

add_region_start	Add the region start offset to the positions.
export_full	Traverse loops and export the MIDI file as it would be played inside Zrythm. If this is 0, only the original region (from true start to true end) is exported.
lanes_as_tracks	Export lanes as separate tracks (only possible with MIDI type 1). This will calculate a unique MIDI track number for the region's lane.
use_track_or_lane_pos	Whether to use the track/lane position in the MIDI data. The MIDI track will be set to 1 if false.
