getChannels

public MidiChannel[] getChannels()

Get the set of MIDI channels controlled by this synth.
Returns:
an array of MIDI channels controlled by this synth

getDefaultSoundbank

public Soundbank getDefaultSoundbank()

Get the default Soundbank for this synth. Return null if there is no default.
Returns:
the default Soundbank for this synth, possibly null.

getLatency

public long getLatency()

The processing latency for this synth in microseconds.
Returns:
the processing latency for this synth in microseconds

getLoadedInstruments

public Instrument[] getLoadedInstruments()

Get an array containing all instruments loaded in this synthesizer.
Returns:
an array containing all instruments loaded in this synthesizer

getMaxPolyphony

public int getMaxPolyphony()

Get the maximum number of notes that the synth can play at once.
Returns:

isSoundbankSupported

public boolean isSoundbankSupported(Soundbank soundbank)

Returns true is this synth is capable of loading soundbank.
Parameters:
soundbank - the Soundbank to examine
Returns:
true if soundbank can be loaded, false otherwise

loadAllInstruments

public boolean loadAllInstruments(Soundbank soundbank)

Load all soundbank instruments into this synthesizer.
Parameters:
soundbank - the Soundbank from which to load instruments
Returns:
true if all instruments were loaded, false othewise
Throws:
IllegalArgumentException - if the soundbank isn't supported by this

loadInstrument

public boolean loadInstrument(Instrument instrument)

Load an instrument into this synth. The instrument must be part of a supported soundbank.
Parameters:
instrument - the Instrument to load
Returns:
true if the instrument was loaded and false otherwise
Throws:
IllegalArgumentException - if this synth doesn't support instrument

loadInstruments

public boolean loadInstruments(Soundbank soundbank,
                               Patch[] patchList)

Load a subset of soundbank instruments into this synthesizer. The subset is defined by an array of Patch objects.
Parameters:
soundbank - the Soundbank from which to load instruments
patchList - the array of patches identifying instruments to load
Returns:
true if instruments were loaded, false otherwise
Throws:
IllegalArgumentException - if the soundbank isn't supported by this

remapInstrument

public boolean remapInstrument(Instrument from,
                               Instrument to)

Parameters:
from - the instrument source
to - the instrument target
Returns:
if from was remapped
Throws:
IllegalArgumentException -

unloadAllInstruments

unloadInstrument

public void unloadInstrument(Instrument instrument)

Unload an instrument from this synth.
Parameters:
instrument - the Instrument to unload
