public interface Soundbank
ASoundbank
contains a set ofInstruments
that can be loaded into aSynthesizer
. Note that a Java SoundSoundbank
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, aSoundbank
can contain 16383 times 128 instruments, because the instruments within aSoundbank
are indexed by both a MIDI program number and a MIDI bank number (via aPatch
object). Thus, aSoundbank
can be thought of as a collection of MIDI banks.Soundbank
includes methods that returnString
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.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.
Soundbanks
andInstruments
that are based on wavetable synthesis (or other uses of stored sound recordings) should typically implement thegetResources()
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.

- a
String
that indicates the sound bank's version
-
getVendor
String getVendor()
Obtains astring
naming the company that provides the sound bank- Returns:
- the vendor string
-
getDescription
String getDescription()
Obtains a textual description of the sound bank, suitable for display.- Returns:
- a
String

.- Parameters:
patch
- aPatch
object specifying the bank index and program change number- Returns:
- the requested instrument, or
