/**
|
||||
* A <code>Patch</code> object represents a location, on a MIDI
|
||||
* synthesizer, into which a single instrument is stored (loaded).
|
||||
* Every <code>Instrument</code> object has its own <code>Patch</code>
|
||||
* 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.
|
||||
* <p>
|
||||
* 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
|
||||
* {@link MidiChannel#programChange(int, int) programChange(int, int)}
|
||||
* method of <code>MidiChannel</code>.
