int CsoundMidiOutputBuffer::GetChannel | ( | ) |
Returns the channel number (1 to 16) for the first message in the buffer.
The return value is zero if there are no messages, or the first message is not a channel message.
int CsoundMidiOutputBuffer::GetData1 | ( | ) |
Returns the first data byte (0 to 127) for the first message in the buffer.
The return value is zero if there are no messages, or the first message does not have any data bytes.
int CsoundMidiOutputBuffer::GetData2 | ( | ) |
Returns the second data byte (0 to 127) for the first message in the buffer.
The return value is zero if there are no messages, or the first message has less than two data bytes.
int CsoundMidiOutputBuffer::GetStatus | ( | ) |
Returns the status byte for the first message in the buffer, not including the channel number in the case of channel messages.
The return value is zero if there are no messages.
int CsoundMidiOutputBuffer::PopMessage | ( | ) |
Pops and returns the first message from the buffer, in the following format: STATUS + DATA1 * 256 + DATA2 * 65536 where STATUS also includes the channel number (0 to 15), if any.
The return value is zero if there are no messages.
