我使用的默认合成器的音库包含各种不同的乐器。例如，这段代码片段...
Synthesizer synthesizer = MidiSystem.getSynthesizer();
synthesizer.open();
Instrument instruments = synthesizer.getDefaultSoundbank().getInstruments();
for (Instrument i : instruments)
System.out.println(i);
...打印以下内容：
Instrument: Piano 1 bank #0 preset #0
Instrument: Piano 2 bank #0 preset #1

Instrument: Applause bank #0 preset #126
Instrument: Gun Shot bank #0 preset #127
Instrument: SynthBass101 bank #128 preset #38
Instrument: Trombone 2 bank #128 preset #57
