<span>一个<code>Patch</code>对象表示在MIDI合成器上存储（加载）单个乐器的位置。</span>
<span>每个<code>Instrument</code>对象都有自己的<code>Patch</code>对象，它指定应该加载该仪器的内存位置。</span>
<span>该位置由银行索引和程序号（不是直接指向RAM中的特定地址或偏移量的任何方案）抽象地指定。</span>
<span>这是一个分层索引方案：MIDI提供多达16384个银行，每个银行最多包含128个程序位置。</span>
<span>例如，最小的合成器可能只有一笔工具，而该银行只有32个工具（程序）。</span>
<p> <span>要选择什么乐器应该在特定的MIDI通道上播放音符，则使用两种MIDI消息来指定一个音色位置：银行选择命令和一个编程改变频道命令。</span> <span>Java的声音相当于是<a href="../../../javax/sound/midi/MidiChannel.html#programChange-int-int-"><code>programChange(int, int)</code></a>的方法<code>MidiChannel</code> 。</span> </p>
