I have just popped in a Midiman midisport 2x2 instead, and that seems

I think the MIDIMAN driver is more stable than the Emagic one at this
point. I have had some weird problems with my AMT8, too, but nothing
that I have absolutely tracked down yet. (I know it doesn't notice
when the device goes offline...)
If you could post the backtraces of the crashes you're seeing, it might
be helpful. If you haven't already, run the Console, and turn on
"Enable crash reporting" and "Automatically display crash logs". When
the MIDIServer crashes, you'll see a log window pop up.
The MIDIServer crashes I have gotten under 10.2 have one of two
backtraces:

This happens when a MIDI client quits. I'm not sure whose fault this
is, but I don't think it happened before I installed the Emagic driver.
The addresses are all in the MIDIServer or CoreMIDIServer.framework, or
in CoreFoundation.

This seems to happen at fairly random times, I think. Running 'nm' on
all my drivers shows that this crash is happening in MOTU's driver.
