Howdy,
In current tip, on OS X 10.8, JUCE’s demo plugin’s “Manufacturer String” shows up in auval and AU Lab as “Juce Demo Plugin” rather than “Raw Material Software”.
Here’s a patch to fix it:
Basically, the “name” field of the plugin in its plist file should be “Raw Material Software: Juce Demo Plugin” rather than “Juce Demo Plugin”.
That’s also the way it is in Apple’s built-in plugins as seen in /System/Library/Components/CoreAudio.component/Contents/Info.plist
Cheers, Yair
