The only variable on line 93 of this is your callback that should field
the input call... Have you added a non-null object to handle the input?
Ideally if you can file a bug and include the code I can take a look at
this...

My first post, being new to the list:
I'm trying to create a midi filter application: read the input, pass
it on or don't according to what's being filtered. I've gotten the
basic idea to work using C++ but want to use Java.
From what I've seen, virtual endpoints (destinationCreate) are "seen"
by MIDIsetup.getSource(), ports (inputPortCreate) are not. I need to
use the virtual variety.
I'm getting the following error:
java.lang.NullPointerException
at
com.apple.audio.midi.MIDIDispatcher.readProc(MIDIDispatcher.java:93)
when I send. Same behavior in 1.3.1 and 1.4.1. Again, the virtual
endpoints work fine in C++.
Any ideas?
Thanks in advance.
