Syntax

public abstract class MetaEvent : MidiEvent

Remarks

Meta event specifies non-MIDI information useful to specific applications.

As with chunks, future meta events may be designed which may not be known to existing programs, so programs must properly ignore meta events which they do not recognize, and indeed, should expect to see them. Programs must never ignore the length of a meta-event which they do recognize, and they shouldn't be surprised if it's bigger than they expected. If so, they must ignore everything past what they know about. However, they must not add anything of their own to the end of a meta-event.

You can create custom meta events that can be read from and written to a MIDI file. See Custom meta events article to learn more.

See https://midi.org/standard-midi-files-specification for detailed MIDI file specification.

Constructors

MetaEvent()

Initializes a new instance of the MetaEvent.

Declaration

protected MetaEvent()

Methods

GetContentSize(WritingSettings)

Gets the size of the content of a MIDI meta event.

Declaration

protected abstract int GetContentSize(WritingSettings settings)

Parameters

Type	Name	Description
WritingSettings	settings	Settings according to which the event's content must be written.

Returns

Type	Description
int	Size of the event's content.

GetStandardMetaEventStatusBytes()

Returns array of status bytes of standard meta events.

Declaration

public static byte[] GetStandardMetaEventStatusBytes()

Returns

Type	Description
byte[]	Array of status bytes of standard meta events.

Remarks

This method can be used for choosing status byte for custom meta event to prevent the status byte is equal to one of the standard ones.

Declaration

protected abstract void ReadContent(MidiReader reader, ReadingSettings settings, int size)

Parameters

Type	Name	Description
MidiReader	reader	Reader to read the content with.
ReadingSettings	settings	Settings according to which the event's content must be read.
int	size	Size of the event's content.

WriteContent(MidiWriter, WritingSettings)

Writes content of a MIDI meta event.

Declaration

protected abstract void WriteContent(MidiWriter writer, WritingSettings settings)

Parameters
