Are there any known issues with CoreMIDI and/or the MIDISPORT 4x4 driver
with dual-cpu machines ?
The MIDISPORT 2x2 (same drivers) gets into an infinite loop under
some circumstances (I think related to handling SysEx).
The next time an application tries to connect to the MIDI Server, it
ends up with a stack trace like the one shown below. I suspect you
will find that the MIDI server is looping and you need to shoot it.
It looked like they had a new version of the driver on the web site,
but when I downloaded, it was the same old one that's been there for
six months (which means it was done before the latest round of
changes in the MIDIServer to driver interface).
I'm having a crash when calling MIDIGetNumberOfDevices( );
here's the stack :
(gdb) bt
#0 0x70013ed8 in syscall_thread_switch ()
#1 0x715a1bc0 in FindOrLaunchServer ()
#2 0x715a1c28 in Initialize ()
#3 0x715a2008 in CheckInitialization ()
#4 0x715a2090 in Send ()
#5 0x715a2df4 in MIDIGetNumberOfDevices ()
#6 0x000025b4 in debugMIDIPrintSystemInfo () at
main.cpp:70/Users/benjamin/prj_/NewCoreMIDITest/
#7 0x000022b0 in main (argc=1, argv=0xbffffa50) at
main.cpp:124/Users/benjamin/prj_/NewCoreMIDITest/
#8 0x00002104 in _start ()
#9 0x00001f34 in start ()
(please note it gets stuck in this call for a few seconds before crash)
The firmware gets loaded in the device before the crash.
I'm using the regular 10.1.2 with the current MIDISPORT driver (2.0.1b).
Hardware : dual 800Mhz 1.25GbRAM
Classic is turned off.
