	)

noexcept

Creates a 3-byte short midi message.

Parameters

byte1	message byte 1
byte2	message byte 2
byte3	message byte 3
timeStamp	the time to give the midi message - this value doesn't use any particular units, so will be application-specific

		double	timeStamp = `0`
	)

noexcept

Creates a 2-byte short midi message.

Parameters

byte1	message byte 1
byte2	message byte 2
timeStamp	the time to give the midi message - this value doesn't use any particular units, so will be application-specific

		double	timeStamp = `0`
	)

noexcept

Creates a 1-byte short midi message.

Parameters

byte1	message byte 1
timeStamp	the time to give the midi message - this value doesn't use any particular units, so will be application-specific

◆ MidiMessage() [4/10]

template<typename... Data>

juce::MidiMessage::MidiMessage	(	int	byte1,
		int	byte2,
		int	byte3,
		Data...	otherBytes
	)

inline

Creates a midi message from a list of bytes.

References jassert.

◆ MidiMessage() [5/10]

juce::MidiMessage::MidiMessage	(	const void *	data,
		int	numBytes,
		double	timeStamp = `0`
	)

Creates a midi message from a block of data.

◆ MidiMessage() [6/10]

juce::MidiMessage::MidiMessage	(	const void *	data,
		int	maxBytesToUse,
		int &	numBytesUsed,
		uint8	lastStatusByte,
		double	timeStamp = `0`,
		bool	sysexHasEmbeddedLength = `true`
	)

Reads the next midi message from some data.

This will read as many bytes from a data stream as it needs to make a complete message, and will return the number of bytes it used. This lets you read a sequence of midi messages from a file or stream.

Parameters

data	the data to read from
maxBytesToUse	the maximum number of bytes it's allowed to read
numBytesUsed	returns the number of bytes that were actually needed
lastStatusByte	in a sequence of midi messages, the initial byte can be dropped from a message if it's the same as the first byte of the previous message, so this lets you supply the byte to use if the first byte of the message has in fact been dropped.
timeStamp	the time to give the midi message - this value doesn't use any particular units, so will be application-specific
sysexHasEmbeddedLength	when reading sysexes, this flag indicates whether to expect the data to begin with a variable-length field indicating its size

◆ MidiMessage() [7/10]

juce::MidiMessage::MidiMessage ( )

noexcept

Creates an active-sense message.

Since the MidiMessage has to contain a valid message, this default constructor just initialises it with an empty sysex message.

◆ MidiMessage() [8/10]

juce::MidiMessage::MidiMessage ( const MidiMessage & )

Creates a copy of another midi message.

◆ MidiMessage() [9/10]

juce::MidiMessage::MidiMessage ( MidiMessage && )

noexcept

Move constructor.
