// This demo shows how to use the MidiInput and MidiOutput types to send and receive
// messages using the traditional bytestream format.
// New programs should prefer to use the newer Universal Midi Packet format whenever
// possible.
// For an example showing how UMP messages can be sent and received, see the UMPDemo,
// as well as the ump::Session, ump::Input, and ump::Output types.
