Obtains a list of instruments that come with the synthesizer.

  Obtains a list of instruments that come with the synthesizer. These instruments might be built into the synthesizer, or they might be part of a default soundbank provided with the synthesizer, etc.

Note that you don't use this method to find out which instruments are currently loaded onto the synthesizer; for that purpose, you use getLoadedInstruments(). Nor does the method indicate all the instruments that can be loaded onto the synthesizer; it only indicates the subset that come with the synthesizer. To learn whether another instrument can be loaded, you can invoke isSoundbankSupported(), and if the instrument's Soundbank is supported, you can try loading the instrument.
Returns: list of available instruments.
See Also: Synthesizer.getLoadedInstruments(), Synthesizer.isSoundbankSupported(Soundbank), Synthesizer.loadInstrument(javax.sound.midi.Instrument),

  Obtains the set of MIDI channels controlled by this synthesizer.

  Obtains the set of MIDI channels controlled by this synthesizer. Each non-null element in the returned array is a MidiChannel that receives the MIDI messages sent on that channel number.

The MIDI 1.0 specification provides for 16 channels, so this method returns an array of at least 16 elements. However, if this synthesizer doesn't make use of all 16 channels, some of the elements of the array might be null, so you should check each element before using it.
Returns: an array of the MidiChannel objects managed by this Synthesizer. Some of the array elements may be null.

  Obtains the default soundbank for the synthesizer, if one exists.

  Obtains the default soundbank for the synthesizer, if one exists.
(Some synthesizers provide a default or built-in soundbank.)
If a synthesizer doesn't have a default soundbank, instruments must
be loaded explicitly from an external soundbank.
Returns: default soundbank, or null if one does not exist.
See Also: Synthesizer.isSoundbankSupported(javax.sound.midi.Soundbank),

  Obtains the processing latency incurred by this synthesizer, expressed in microseconds.

  Obtains the processing latency incurred by this synthesizer, expressed in microseconds. This latency measures the worst-case delay between the time a MIDI message is delivered to the synthesizer and the time that the synthesizer actually produces the corresponding result.

Although the latency is expressed in microseconds, a synthesizer's actual measured delay may vary over a wider range than this resolution suggests. For example, a synthesizer might have a worst-case delay of a few milliseconds or more.
Returns: the worst-case delay, in microseconds

  Obtains a list of the instruments that are currently loaded onto this Synthesizer.

  Obtains a list of the instruments that are currently loaded onto this
Synthesizer.
Returns: a list of currently loaded instruments
See Also: Synthesizer.loadInstrument(javax.sound.midi.Instrument), Synthesizer.getAvailableInstruments(), Soundbank.getInstruments(),

  Obtains the maximum number of notes that this synthesizer can sound simultaneously.

  Obtains the maximum number of notes that this synthesizer can sound simultaneously.
Returns: the maximum number of simultaneous notes
See Also: Synthesizer.getVoiceStatus(),

  Obtains the current status of the voices produced by this synthesizer.

  Obtains the current status of the voices produced by this synthesizer.
If this class of Synthesizer does not provide voice
information, the returned array will always be of length 0. Otherwise,
its length is always equal to the total number of voices, as returned by
getMaxPolyphony(). (See the VoiceStatus class
description for an explanation of synthesizer voices.)
Returns: an array of VoiceStatus objects that supply information about the corresponding synthesizer voices
See Also: Synthesizer.getMaxPolyphony(), VoiceStatus,

  Informs the caller whether this synthesizer is capable of loading instruments from the specified soundbank.

  Informs the caller whether this synthesizer is capable of loading
instruments from the specified soundbank.
If the soundbank is unsupported, any attempts to load instruments from
it will result in an IllegalArgumentException.
Returns: true if the soundbank is supported, otherwise false
Parameters:
- soundbank - soundbank for which support is queried
See Also: Synthesizer.loadInstruments(javax.sound.midi.Soundbank, javax.sound.midi.Patch[]), Synthesizer.loadAllInstruments(javax.sound.midi.Soundbank), Synthesizer.unloadInstruments(javax.sound.midi.Soundbank, javax.sound.midi.Patch[]), Synthesizer.unloadAllInstruments(javax.sound.midi.Soundbank), Synthesizer.getDefaultSoundbank(),

  Loads onto the Synthesizer all instruments contained in the specified Soundbank.

  Loads onto the Synthesizer all instruments contained
in the specified Soundbank.
Returns: true if the instruments are all successfully loaded (or already had been), false if any instrument could not be loaded (for example, if the Synthesizer had insufficient memory)
Parameters:
- soundbank - the Soundbank whose are instruments are to be loaded
Throws:
- IllegalArgumentException - if the requested soundbank is incompatible with this synthesizer.
See Also: Synthesizer.isSoundbankSupported(javax.sound.midi.Soundbank), Synthesizer.loadInstrument(javax.sound.midi.Instrument), Synthesizer.loadInstruments(javax.sound.midi.Soundbank, javax.sound.midi.Patch[]),

  Makes a particular instrument available for synthesis.

  Makes a particular instrument available for synthesis. This instrument is loaded into the patch location specified by its Patch object, so that if a program-change message is received (or has been received) that causes that patch to be selected, subsequent notes will be played using the sound of instrument. If the specified instrument is already loaded, this method does nothing and returns true.

The instrument must be part of a soundbank that this Synthesizer supports. (To make sure, you can use the getSoundbank method of Instrument and the isSoundbankSupported method of Synthesizer.)
Returns: true if the instrument is successfully loaded (or already had been), false if the instrument could not be loaded (for example, if the synthesizer has insufficient memory to load it)
Parameters:
- instrument - instrument to load
Throws:
- IllegalArgumentException - if this Synthesizer doesn't support the specified instrument's soundbank
See Also: Synthesizer.unloadInstrument(javax.sound.midi.Instrument), Synthesizer.loadInstruments(javax.sound.midi.Soundbank, javax.sound.midi.Patch[]), Synthesizer.loadAllInstruments(javax.sound.midi.Soundbank), Synthesizer.remapInstrument(javax.sound.midi.Instrument, javax.sound.midi.Instrument), SoundbankResource.getSoundbank(), MidiChannel.programChange(int, int),

  Loads the instruments referenced by the specified patches, from the specified Soundbank.

  Loads the instruments referenced by the specified patches, from the
specified Soundbank. Each of the Patch objects
indicates a bank and program number; the Instrument that
has the matching Patch is loaded into that bank and program
location.
Returns: true if the instruments are all successfully loaded (or already had been), false if any instrument could not be loaded (for example, if the Synthesizer had insufficient memory)
Parameters:
- soundbank - the Soundbank containing the instruments to load
- patchList - list of patches for which instruments should be loaded
Throws:
- IllegalArgumentException - thrown if the soundbank is not supported.

  Remaps an instrument.

  Remaps an instrument. Instrument to takes the place of instrument from.
For example, if from was located at bank number 2, program number 11, remapping causes that bank and program location to be occupied instead by to.
If the function succeeds, instrument from is unloaded.

To cancel the remapping reload instrument from by invoking one of Synthesizer.loadInstrument(javax.sound.midi.Instrument), Synthesizer.loadInstruments(javax.sound.midi.Soundbank, javax.sound.midi.Patch[]) or Synthesizer.loadAllInstruments(javax.sound.midi.Soundbank).
Returns: true if the instrument succeessfully remapped, false if feature is not implemented by synthesizer
Parameters:
- from - the Instrument object to be replaced
- to - the Instrument object to be used in place of the old instrument, it should be loaded into the synthesizer
Throws:
- IllegalArgumentException - if instrument from or instrument to aren't supported by synthesizer or if instrument to is not loaded
- NullPointerException - if from or to parameters have null value
