Here's a surprise. Oddity AU is blowing chunks if I set the
BeatAndTempo property on it! Not immediately, put pretty soon after.
Here's a portion of the call stack - looks surprisingly shallow:
Thread 3 Crashed:
#0 0x05c25004 in 0x5c25004
#1 0x05bd52b4 in
AUMIDIBase::ComponentEntryDispatch(ComponentParameters*, AUMIDIBase*)
(AUMIDIBase::ComponentEntryDispatch(ComponentParameters*, AUMIDIBase*)
+ 88)
#2 0x05bd5478 in
MusicDeviceBase::ComponentEntryDispatch(ComponentParameters*,
MusicDeviceBase*)
(MusicDeviceBase::ComponentEntryDispatch(ComponentParameters*,
MusicDeviceBase*) + 108)
#3 0x05b72418 in AUMusicDeviceEntry (AUMusicDeviceEntry + 120)
#4 0x90281a90 in CallComponent (CallComponent + 212)
#5 0x91a90a0c in MusicDeviceMIDIEvent (MusicDeviceMIDIEvent + 52)
As a comparison but Zebra and Albino are happy with the tempo settings.
Has anyone else had success with this property and Oddity?
Robert.

Attempting to support this in my Rax update, but had a question:
Is the "outCurrentBeat" indexed from 0 or 1?
It is from 0.
