// Description:   An interface for MIDI input capabilities of
//                an unknown sound driver's specific MIDI input methods.
//                This class is inherited privately by the MidiInPort class.
//                This class is used when there is no MIDI input, so
//                that MIDI programs can otherwise be compiled and run.
//                This file can also serve as a template for creating
//                an OS specific class for MIDI input.
