I've been having divergent results with the AU version of PhaseRaise, a mini-plugin that I'm hoping to have up on my site in the next couple days. From the testing I've conducted, the Mac VST & Windows VST 32/64bit all work well & load in all the hosts I have access to, but the AU build is very inconsistant.
On my computer, Mac OSX 10.9.1:
•The AU validates and loads fine on Logic Pro 9.1.8, Ableton Live 9.1.1, Izotope RX 3, Reaper 4.55
•The AU does not load in DSP Qauttro (Although the VST opens fine), nor any of the JUCE plug-ins (including the demo) for that matter. All other AU plug-ins open fine.
On other computers:
•The AU does not validate on my friend's system (Mac OSX Lion, Logic Pro 9.1.5)
•The AU works on my brother's System (Mac OSX 10.9.1, Garageband) Garageband doesn't use auVal, though, to my knowledge.
I'm pretty stumped on this one, but I need to gather more data (DSP Quattro doesn't seem to write to the console output when errors occur...although the JUCE debugger strings don't show up in the console since upgrading to Mavericks either...)
Below is a dropbox link if anybody who's running logic could let me know if it works for them.
