CsoundMidiOutputStream (CSOUND *csound) | |
CsoundMidiOutputStream (Csound *csound) | |
void | EnableMidiOutput (CsoundArgVList *argv) |
Enables MIDI output for the associated Csound instance. | |
int | GetChannel () |
Returns the channel number (1 to 16) for the first message in the buffer. | |
int | GetData1 () |
Returns the first data byte (0 to 127) for the first message in the buffer. | |
int | GetData2 () |
Returns the second data byte (0 to 127) for the first message in the buffer. | |
int | GetStatus () |
Returns the status byte for the first message in the buffer, not including the channel number in the case of channel messages. | |
int | 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. | |

void CsoundMidiOutputStream::EnableMidiOutput | ( | CsoundArgVList * | argv | ) |
Enables MIDI output for the associated Csound instance.
Should be called between csoundPreCompile() and csoundCompile(). If 'argv' is not NULL, the command line arguments required for MIDI output are appended.

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.
|
inherited |
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.
|
inherited |
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.
|
inherited |
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.
