I cannot seem to get AU Lab to see the FilterDemo v3 AU created by the Apple sample code in AU Lab. I can see it in Garage Band. I found some references to AU Lab not supporting v3 AUs, though it is almost shocking that an Apple test tool doesn't support AU v3. I looked for a later version of AU Lab but that is also frustrating (my version is 2.2.2).
So the question is simple - is there a version of AU Lab that does support v3 AUs, and if so, where can I find it?
If not, can someone recommend a good alternative? Using GarageBand or Logic Pro is really not what I want to do when I'm testing AudioUnits, especially when I want more free form routing.
