Hi Bill,
Rather than re-scanning when seeing this or that version number, why not simply re-scan a plug-in when the component file changes? That seems like the most logical behavior, and is what I would have expected behavior-wise from *any* host before Brain tipped me to the obscure version number detail.
My problem occurred because I compiled my project with the wrong channel config *once* in the past. When I corrected the channel configuration reporting, I would have expected Logic and AU Lab to see the change, but neither did, because the version number was held constant (and was not 0x0 or 0xFFFF...).
Trying to correct the issue, I had totally removed the plug-in, and confirmed that Logic and AU Lab no longer saw it. At that point I would have expected that component to be removed from the component manager in the system. Why keep it around? Perhaps that's a bug? Or is there a good reason for that?
Thanks,
Chris

Had to manually clear the audiounits cache at

Apparently Logic/AULab do not do a proper re-scan/re-validation of a plugin once it is removed/replaced in the system. If you have a rebuild of a plugin that you change the channel capability of, you'll have to clear the cache to get the system to see it properly.
Hope this helps someone else out there!
Thanks,
Chris

I'm trying to implement an audio unit (type aufx) with the ability for mono->stereo and stereo->stereo, but NOT mono->mono.
My AU subclasses from AUMIDIEffectBase and properly overrides the SupportedNumChannels function.
If I run the AU Validation tool on it, it shows the proper channel handling capabilities.
//-------------------------------------------------------
Reported Channel Capabilities (explicit):
[1, 2] [2, 2]
Input/Output Channel Handling:
1-1 1-2 1-4 1-5 1-6 1-7 1-8 2-2 2-4 2-5 2-6 2-7 2-8 4-4 4-5 5-5 6-6 7-7 8-8
X X
//-------------------------------------------------------
However, both AULab and Logic 8 show a mono->mono option, even though it isn't there.
Is this a bug in Logic or am I doing something wrong? Has anyone else experienced problems with this? I've also tried every combination of removing/restarting/rebuilding I could think of, in case the component manager might be caching out-of-date information.
Best,
Chris
