◆ MidiMessage() [1/10]
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
◆ MidiMessage() [2/10]
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
◆ MidiMessage() [3/10]
|
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]
|
inline |
Creates a midi message from a list of bytes.
◆ MidiMessage() [5/10]
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]
