Detailed Description

A realtime MIDI output class.

This class provides a common, platform-independent API for MIDI output. It allows one to probe available MIDI output ports, to connect to one such port, and to send MIDI bytes immediately over the connection. Create multiple instances of this class to connect to more than one MIDI device at the same time.

Constructor & Destructor Documentation

RtMidiOut::RtMidiOut  
 

Default constructor.

An exception will be thrown if a MIDI system initialization error occurs.


Member Function Documentation

void RtMidiOut::openPort unsigned int    portNumber = 0 [virtual]
 

Open a MIDI output connection.

An optional port number greater than 0 can be specified. Otherwise, the default or first port found is opened. An exception is thrown if an error occurs while attempting to make the port connection.

Implements RtMidi.

void RtMidiOut::openVirtualPort   [virtual]
 

Create a virtual output port to allow software connections (OS X and ALSA only).

This function creates a virtual MIDI output port to which other software applications can connect. This type of functionality is currently only supported by the Macintosh OS-X and Linux ALSA APIs (the function does nothing with the other APIs). An exception is thrown if an error occurs while attempting to create the virtual port.

Implements RtMidi.

std::string RtMidiOut::getPortName unsigned int    portNumber [virtual]
 

Return a string identifier for the specified MIDI port type and number.

An exception is thrown if an invalid port specifier is provided.

Implements RtMidi.

void RtMidiOut::sendMessage std::vector< unsigned char > *    message
 

Immediately send a single message out an open MIDI output port.

An exception is thrown if an error occurs during output or an output connection was not previously established.
