I'm using an external MIDI monitor program (MIDI-OX).

I guess default Synthesizer (returned by MidSystem.getSysnthsizer()) on
my system is software synth of Windows.  But I hear nothing.

It seems my XP system is worse than Linux.

I have not decided to install 1.5 yet.
I don't prefer to install beta version.  And I'm afraid having two
version of SDK will cause trouble for me.

You can use core.Utility.getJavaVersion() and disable sequencer
without waiting for the time when 1.5 will be requirement.
