I will post this - here at this forum as well. Have already posted it at http://www.unicornation.com/.
Hope this can help someone else:

As of late I have been having progressively more/worse midi-related problems with DP4.
( I readily confess to NOT being very versed in things midi )

With much appreciated help of Nathan (tech-support) at Motu, we have formulated a long & rather boring process for eliminating these particular problems.

In short when I'm working with audio only, everything is smooth sailing, steady as a rock.
As soon as I'm doing any midi-recording and/or midi-editing, the infamous "SBFH" puts in an encore.

Either forcing a "Force quit" from the Apple-menu, or killing off the MIDIServer process - in the terminal window.

Below is the entire 22-step proces for coming to grips with this:
--------------

1:) Remove all FW USB adio & midi-interfaces from your computer.

2:) Reboot your computer

3:) Uninstall all fw and usb-drivers

4:) Open a new project in DP4/DP4.0.1

5:) Put DP in MIDI only mode. "Setup"-menu --> Audio System --> MIDI Only

6:) Go to: "Setup"-menu --> Interapplication MIDI...

7:) In the "Interapplication MIDI" - dialog -- check the "Software Synthesizer"

9:) Create a number of midi tracks - 6 to 8 tracks will do.

10:) Using the pencil tool only, add midi notes into the tracks

11:) Loop the sequence let it play for an hour or two or 24, whatever.

12:) If this plays along fine start adding things back in.

13:) Reconnect your usb/fw - midi-interface and install the proper latest driver.

14:) Reboot your computer.

15:) Go To "Audio/MIDI Prefs" - utility. Setup your minimum studio.
Connect "ONE" cable from your interface to the midi-in on your synth-module.

16:) Do the same in the real world, i.e. between your interface and & your synth.
Only one cable from Interface midi-out to your synth midi-in, will prevent midi log jams.

17:) If this plays back without a hitch, through your synthesizer module. Connect the next cable
in both the "Audio/MIDI prefs" - utility and between your interface and synth.
From interface midi-in - to synth midi-out

18:) If this plays back OK, add your other synth:s and keyboard controller back in one cable at
a time. Like in paragraphs 15,16 & 17.

20:) If this plays back OK, start recording over or add more midi-tracks using your
keyboard-controller as input.

21:) If this plays back OK with the new tracks added your are probaly green-lighted and set to go.
If NOT, open the eventlists (select the tracks & press Shift+E keys at the same time)
for the newly recorded tracks. Look or search for recorded midi-exclusive messages if any.

22:) Select and remove all the system exclusive messages. At least as many as possible.
Do the same for any midi-track you see midi-exclusives in.
-------------------------------------------------------------------------

( I suspect the midi-exclusives to be the culprit - you can try to take the short route and only do paragraph 22 )

After doing this my midi-problems seem to have disappeared.
I hope this can be of help to someone.

PS- forgot to mention.

When you have successfully come to paragraph 22, without falling asleep -
you can add your favourite audio interface back in and install the proper latest driver for that as well.
