A convenience method would meet my needs, something like:
AudioInputStream getAudioInputStream(Sequence seq, AudioFormat targetFormat)
throws MidiUnavailableException, UnsupportedAudioFileException;
An AudioSynthesizer interface (of some form) might be useful to select among
multiple software synthesizers, if that should ever happen, and might be useful
as a service provider interface.
