public class RealtimePlayer
This player sends messages directly to the MIDI Synthesizer, rather than creating a
sequence with the MIDI Sequencer.
There are two ways that you can send messages to RealTimePlayer, and you can freely intermix these:
1. Pass any Staccato string to the play() method. In this case, start notes should be indicated as the start of a tie
(e.g., "C4s-") and stop notes should be indicated as the end of a tie (e.g., "C4-s")
2. Call specific methods, like startNote or changeInstrument
