Strictly speaking, this isn't a programming problem, except that
it's preventing me from doing the MIDI programming I need to be
doing right now. I've installed an M-Audio Audiophile MIDI
interface on my 10.3.9 PowerBook and on my 10.4.4 PowerBook. On
the Tiger PowerBook, everything works fine, but on Panther, even
though I can set General Preference/Sound input and output to my
Audiophile MIDI interface, MIDI doesn't work at all. When I start
up Finale, I get the following error message: "An error occurred
while attempting to use CoreMIDI." When I try to start up Audio
MIDI Setup and choose MIDI Devices, I get "Loading" and the
spinning cursor for quite a while, and then I get "Application has
unexpectedly quit." All of this works fine on Tiger, but I really
need MIDI to work on Panther too. I did recently install QuickTime
7.0.4 on my Panther computer, but it messed up some vital software
on that computer, so I actually downgraded QuickTime all the way
back to 6.5.2. Since then, I've tried reinstalling 10.3.9, but it
hasn't solved the CoreMIDI problem. Is there anything else I
should try before I just give up and do a clean reinstall of
10.3.9? (And yes, I know I should be using the latest version of
XCode on Tiger, but that's not a viable option at this moment
because I foolishly put Tiger on my "bad" PowerBook instead of my
good one.)
It sounds like M-Audio driver is crashing MIDIServer. I apologize to
M-Audio for singling them out here ... but:
[a] it really sounds like MIDIServer is crashing (IIRC, Audio MIDI
Setup is much more likely to crash when MIDIServer crashes under
Panther than on Tiger)
[b] a recent scan of the crash reports for MIDIServer indicates that
something like 99% of all crashes are in third-party MIDI driver code.
I suggest tracking down and removing the M-Audio drivers. If the
crashes stop, then see if there's a newer driver or contact M-Audio.
If the crashes don't stop, please send a crash report for MIDIServer
(grab one or two from ~/Library/Logs/CrashReporter/
MIDIServer.crash.log) ... either to this list or in bugreporter.
Thanks
Doug
