Default [5.79 onwards] 32-bit AU plugins not working on OSX 64-bit

Hi there,

I still use some 32 bit plugins since upgrading to 64-bit Reaper, and noticed recently that my 32-bit AUs stopped working - as in they don't parse audio at all. So if I put a 32-bit AU plugin on a track, the audio output of the track stops, until I bypass that plugin in the FX chain panel, and it resumes again. Also the GUI of some plugins aren't responding to any audio input (eg. freq analysers).

I tried every version of Reaper in the last 6 months and tracked down that the issue appeared in 5.79 - where one of the changes listed was "Audio Units: improve support for AU that use multiple buses but do not support channel-configuration (e.g. Addictive Drums AUi)"... perhaps this had something to do with it?

Guessing this is not a problem that will affect many people but it would be nice to still be able to use some of my old plugins when the need arises... reluctant to upgrade until I have to!
