VST's fine, AU not so much

#1

I’ve got a JAPF soundfont instrument project that works fine as a VSTi but not as an AU. I’m using Rax and AU Lab to test. If I do a debug build then neither host can open my UI. If I do a release build then the UI opens fine, but my plugin never gets any midi events. Also, in AU Lab if I add my VSTi as the first instrument then the audio engine doesn’t turn on. Adding another instrument first, then mine allows the audio engine to turn on, but I still never get midi events. Both debug and release builds work properly as VSTi.

Any suggestions on how to debug this?

I’m developing this on OS X, with Juce 1.43.

Thanks,

I just tried the juce demo and ppmulator in AULab, and they seem absolutely fine - sounds most likely that you’ve got a bug in your code that’s only getting triggered by some difference in the order in which things happen with an AU? You can debug with AULab anyway - just tell xcode to launch it as the executable.
