/**
 * Demonstrates JMSL support for SynthNotes with more than one SynthOutput
 * defined. See SquareSineSawSynthNote for an example on how to massage your
 * SynthNotes to fit into this scheme. Note that this is different that a
 * SynthNote with a single "output" with one or more parts. Those already fit
 * into SynthNoteAllPortsInstrument without the need for any changes to the
 * SynthNote source code. This example however, covers SynthNotes that literally
 * have multiple outputs defined (output, output2, output3, etc) and how to
 * support that. When JSyn supports an output unit that can have multiple inputs
 * assigned to indexed parts, this will become obsolete
