// Syntax: C++
//
// 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.
