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.

/**
* Instrument patch

private final Patch patch;
Constructs a new MIDI instrument from the specified Patch.
When a subsequent request is made to load the
instrument, the sound bank will search its contents for this instrument's Patch,
and the instrument will be loaded into the synthesizer at the
bank and program location indicated by the Patch object.
Params: - soundbank – sound bank containing the instrument
- patch – the patch of this instrument
- name – the name of this instrument
- dataClass – the class used to represent the sample's data.
