Well, I don't know if the midi test methods I wrote 2 years ago are 
still in the source but, if they are, you can use them (with a midi 
cable looping your interface's OUT to the IN) to do a "sanity check". 
This would let you know if the problem lies in the low-level parts (ie a 
problem in the methods of your current java-midi driver, or the 
lower-level midi drivers in your OS, or the midi interface itself or the 
cable).

The way things were headed back before the aliens abducted me, the midi 
layer was intended to completely encapsulate the creation, sending, and 
receiving of all midi messages. So, if things are still 
well-encapsulated, the problem *should* be in the midi driver. Which one 
are you using? I'm not even sure which ones are still in the package. 
JavaMidi, jMidi, ALSA, OSX?
