I`ll try to build JuceDemo AU for ppc(or universal).
It builds, but does not recognized as AU by Rax 1.2.3(ppc AU host).
Rax works fine with 3-rd party pcc plug-ins.
I check info.plist data, component package. All looks health.
Bug from hxxp://www.rawmaterialsoftware.com/juceforum/viewtopic.php?t=2588(hxxp://lists.apple.com/archives/coreaudio-api/2007/Nov/msg00040.html )fixed.
VST ppc version works good(with juce host builds to ppc).
Intel build works fine.
P.S. Sorry for pure english.
