double  timeStamp = 0 
)
noexcept

Creates a 1-byte short midi message.

Parameters
byte1message byte 1
timeStampthe time to give the midi message - this value doesn't use any particular units, so will be application-specific

Definition at line 117 of file juce_MidiMessage.cpp.

◆ 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.

Definition at line 67 of file juce_MidiMessage.h.

◆ MidiMessage() [5/10]

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

Creates a midi message from a block of data.

Definition at line 107 of file juce_MidiMessage.cpp.

◆ 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
datathe data to read from
maxBytesToUsethe maximum number of bytes it's allowed to read
numBytesUsedreturns the number of bytes that were actually needed
lastStatusBytein 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.
timeStampthe time to give the midi message - this value doesn't use any particular units, so will be application-specific
sysexHasEmbeddedLengthwhen reading sysexes, this flag indicates whether to expect the data to begin with a variable-length field indicating its size

Definition at line 165 of file juce_MidiMessage.cpp.

◆ MidiMessage() [7/10]

If the message is being used in a MidiBuffer, it might indicate the number of audio samples from the start of the buffer.

If the message was created by a MidiInput, see MidiInputCallback::handleIncomingMidiMessage() for details of the way that it initialises this value.
