SendProgramChange() public method

Sends a Program Change message to this MIDI output device.
A Program Change message is used to switch among instrument settings, generally instrument voices. An instrument conforming to General Midi 1 will have the instruments described in the Instrument enum; other instruments may have different instrument sets.
channel or instrument is out-of-range. /// The device is not open. The message cannot be sent.
