Hey guys,
I have a sample java program that does a beat box using midi:
(url not allowed google "beatbox.java head first")
(sorry I have a new user name and no url privileges yet.)

And I can't get it to produce any sound on my linux box.

Here's what I've done:

alsa is installed and works
timidity can play a midi file (though i suspect this is unrelated)
I installed a soundbank from sun
(url not allowed google java midi soundbank)

(did i put this in the right place?)
/usr/java/jdk1.5.0_12/jre/lib/audio/soundbank.gm
/usr/java/jdk1.5.0_12/lib/audio/README-soundbank.txt
/usr/java/jdk1.5.0_12/lib/audio/soundbank-deluxe.gm
/usr/java/jdk1.5.0_12/lib/audio/soundbank-deluxe.gm.zip


The program exhibits the same behavior as windows/mac,
ie, throws no exceptions, doesn't crash etc, but no sound
is generated.

Here's my setup:
lenovo X61s
opensuse 10.2
java 5
alsa is from cvs (newish chip)

Am I missing another piece for midi generation?
Is there a device I need to set up?
Can test the midi subsystem from something other than the
java API to help locate the problem?


thanks

Benjamin

Yes, this is (probably) unrelated. Timidity++ will convert a MIDI file to sound information and output it to the soundcard as a “wave” file (the PCM channel). The program you are writing most likely attempts to use the soundcard’s MIDI hardware to do this work. To check if your alsa setup correctly uses your soundcard as a sequencer, you might try to tell timidity to use the hardware or try a sequencer-based (i.e., non-software-based rendering) MIDI file player (e.g., playmidi).

As an alternative, if you don’t like the sound of your hardware sequencer compared to timidity (or like the prospect of sound fonts and such), you can use timidity as a server which provides alsa a virtual MIDI sequencer. This device can be made the default and would be used by playmidi and other players which access the sequencer.

I accidentally posted this twice,
