* 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.
