/**
|
|
* An instrument is a sound-synthesis algorithm with certain parameter
|
|
* settings, usually designed to emulate a specific real-world
|
|
* musical instrument or to achieve a specific sort of sound effect.
|
|
* Instruments are typically stored in collections called soundbanks.
|
|
* Before the instrument can be used to play notes, it must first be loaded
|
|
* onto a synthesizer, and then it must be selected for use on
|
|
* one or more channels, via a program-change command. MIDI notes
|
|
* that are subsequently received on those channels will be played using
|
|
* the sound of the selected instrument.
