Patch (Java SE 9 & JDK 9 )

java.lang.Object
- javax.sound.midi.Patch

```
public class Patch
extends Object
```
A Patch object represents a ___location, on a MIDI synthesizer, into which a single instrument is stored (loaded). Every Instrument object has its own Patch object that specifies the memory ___location into which that instrument should be loaded. The ___location is specified abstractly by a bank index and a program number (not by any scheme that directly refers to a specific address or offset in RAM). This is a hierarchical indexing scheme: MIDI provides for up to 16384 banks, each of which contains up to 128 program locations. For example, a minimal sort of synthesizer might have only one bank of instruments, and only 32 instruments (programs) in that bank.
To select what instrument should play the notes on a particular MIDI channel, two kinds of MIDI message are used that specify a patch ___location: a bank-select command, and a program-change channel command. The Java Sound equivalent is the programChange(int, int) method of MidiChannel.
