thanks for the ideas. it is a consumer path and so it is red. an
interpolator is connected to it that loops through note on msgs 52-76
with velocity set to 100.
i am getting there. i can not see the logs in the console. and in
MIDIMonitor app, I can see the messages. But i am not getting any
softsynth to play (even DLS Synth within MIDIPipe). It appears to be
finding all of the destinations though (except Logic).
Also, the build put the package in a strange place and it does not
appear that Apples templates for QC plugins place the patches in the
right location. Again, I am a green stick with XCODE and Obj-C

Has anyone else worked with MIDI in a QC plugin?
We've done a fair amount with midi in QC. Looks like you're doing
things right in a general sense, but I've only given it a once-over.
Things that came to mind: Is your patch's execute method getting
called each frame? Throw some NSLog()'s (or the QC-sanctioned
equivalent, not sure off the top of my head) and see what it's doing
each frame. If it's not a consumer patch (red title bar), it will
only get executed if it's attached to a red one that's enabled
somewhere down the line. Its timemode may also factor into this, if
it's not a red patch (honestly, I'm a bit rusty regarding how red
patches handle timemode compared to green and blue patches).
If that doesn't work out, let me know and I can take a closer peek
to see what's happening.
