MIDI getting killed by Jack?

["Mark Knecht" <mknecht@controlnet.com>]

Hi,
   I posted this last night on LAU but received no responses. Either it
was of no interest or just no one had anything to say about it.

   Is anyone else experiencing this problem? I set up a bunch of
aconnect commands to route my keyboard controller (64:0) to a number of
synths on different MIDI interfaces, and also to route the output of Pro
Tools (on another computer - 80:0) to pretty much the same places:

aconnect 64:0 64:32
aconnect 64:0 80:1
aconnect 80:0 64:0
aconnect 80:0 64:32
aconnect 80:0 80:1

I also route Pro Tools output back to my keyboard (line 3) in case I
want to plug another hardware synth in there, but nothing is hooked up
to that right now.

At this point I set up my mixer and play. Everything works and is
perfectly fine for long periods of time.

I then start Jack and within a minute or two I lose MIDI connectivity. I
can run alsaplayer or other audio apps and I still get audio, but there
is no more MIDI connectivity. I look at the synths and they are not
receiving MIDI input. (No event lights.)

I then stop Jack and I immediately hear a bunch of MIDI notes get
played. These notes were stored from when I wasn't getting connectivity.
At this point I have MIDI back for live playing until the next time I
start Jack when it happens again.

I do this 4 or 5 times and at this point I cannot get MIDI back at all.
I have to completely power down as far as I can tell. I tried rebooting
and had no luck the one time I did that.

I don't know what to look at to figure out what could be causing this.
Hardware and modules shown below.

In thinking about this overnight it dawned on me that I am only seeing 
this problem on MIDI generated by my controller hooked to the HDSP
MIDI input. I do not see this problem on MIDI generated by Pro Tools
hooked to the MidiSport. I will likely rewire what is hooked to what
this evening and see if I can say that it is only the HDSP input, or
something else.

Thanks,
Mark
