The non-realtime buffer size and the realtime buffer size are both optional arguments.

jack_nframes_t Jack::JackPhysicalMidiOutput::Advance | ( | jack_nframes_t | frame | ) | [protected, virtual] |
Override to specify the next frame at which a midi byte can be sent. The returned frame must be greater than or equal to the frame argument. The default returns the frame passed to it.
Definition at line 57 of file JackPhysicalMidiOutput.cpp.
void Jack::JackPhysicalMidiOutput::HandleEventLoss | ( | JackMidiEvent * | event | ) | [protected, virtual] |
Override to customize how to react when a MIDI event can't be buffered and can't be sent immediately. The default calls 'jack_error' and specifies the number of bytes lost.

virtual jack_nframes_t Jack::JackPhysicalMidiOutput::Send | ( | jack_nframes_t | , |
jack_midi_data_t | |||
) | [protected, pure virtual] |
This method *must* be overridden to specify what happens when a MIDI byte is sent at the specfied frame. The frame argument specifies the frame at which the MIDI byte should be sent, and the second argument specifies the byte itself. The return value is the next frame at which a MIDI byte can be sent, and must be greater than or equal to the frame argument.
jack_nframes_t Jack::JackPhysicalMidiOutput::SendBufferedData | ( | jack_ringbuffer_t * | buffer, |
jack_nframes_t | current_frame, | ||
jack_nframes_t | boundary | ||
) | [protected, virtual] |
Override to optimize behavior when sending MIDI data that's in the ringbuffer. The first frame argument is the current frame, and the second frame argument is the boundary frame. The function returns the next frame at which MIDI data can be sent, regardless of whether or not the boundary is reached. The default implementation calls 'Send' with each byte in the ringbuffer until either the ringbuffer is empty, or a frame beyond the boundary frame is returned by 'Send'.

void Jack::JackPhysicalMidiOutput::Process | ( | jack_nframes_t | frames | ) |
Called to process MIDI data during a period.
Definition at line 90 of file JackPhysicalMidiOutput.cpp.
void Jack::JackPhysicalMidiOutput::SetPortBuffer | ( | JackMidiBuffer * | port_buffer | ) | [inline] |
Set the MIDI buffer that will contain the outgoing MIDI messages.
