package javax.sound.midi;
/**
* A {@code Soundbank} contains a set of {@code Instruments} that can be loaded
* into a {@code Synthesizer}. Note that a Java Sound {@code Soundbank} is
* different from a MIDI bank. MIDI permits up to 16383 banks, each containing
* up to 128 instruments (also sometimes called programs, patches, or timbres).
* However, a {@code Soundbank} can contain 16383 times 128 instruments, because
* the instruments within a {@code Soundbank} are indexed by both a MIDI program
* number and a MIDI bank number (via a {@code Patch} object). Thus, a
* {@code Soundbank} can be thought of as a collection of MIDI banks.
* <p>
* {@code Soundbank} includes methods that return {@code String} objects
* containing the sound bank's name, manufacturer, version number, and
* description. The precise content and format of these strings is left to the
* implementor.
* <p>
* Different synthesizers use a variety of synthesis techniques. A common one is
* wavetable synthesis, in which a segment of recorded sound is played back,
* often with looping and pitch change. The Downloadable Sound (DLS) format uses
* segments of recorded sound, as does the Headspace Engine. {@code Soundbanks}
* and {@code Instruments} that are based on wavetable synthesis (or other uses
* of stored sound recordings) should typically implement the
* {@code getResources()} method to provide access to these recorded segments.
* This is optional, however; the method can return an zero-length array if the
* synthesis technique doesn't use sampled sound (FM synthesis and physical
* modeling are examples of such techniques), or if it does but the implementor
* chooses not to make the samples accessible.
