public void setMessage(int type, byte[] data, int length) throws InvalidMidiDataException
MetaMessage
.
Since only one status byte value, 0xFF
, is allowed for meta-messages,
it does not need to be specified here. Calls to getStatus
return
0xFF
for all meta-messages.
The type
argument should be a valid value for the byte that
follows the status byte in the MetaMessage
. The data
argument
should contain all the subsequent bytes of the MetaMessage
. In other words,
the byte that specifies the type of MetaMessage
is not considered a data byte.
type
- meta-message type (must be less than 128)data
- the data bytes in the MIDI messagelength
- the number of bytes in the data
byte array
InvalidMidiDataException
