Null pointer / midi synthetizer

[GoogleCodeExporter]

Second, while trying to convert ABC contents to MIDI, I discovered that a
MIDI synthesizer must be open, like this:

Synthesizer synth = MidiSystem.getSynthesizer();
synth.open();

... conversion ...

synth.close();

I left out the exception handling. It would be nice to know this little
fact, because without doing so one will surely wonder why he is getting all
those NullPointerException-s trying to convert ABC to MIDI.
