I have used the current audio unit tutorial (1) with a bit of tinkering to create an Xcode project (2) that successfully builds a component but I can’t get it to validate. AUVal gives me error -10878. (3)
I started in Xcode from the 'OS X > System Plug-in > Generic C++ plugin’ template and copied all the methods in the tutorial for making the sample audio unit (TremoloUnit) as well as a couple of methods that were in the downloadable sample audio unit that seemed necessary to get it to build - essentially trying to mimic the mythical audio unit template that the guide refers to, but which is no longer available in Xcode and has been unavailable for some time. I think I have ended up implementing a version of every method in the sample audio unit so I’m now stuck as to why it doesn’t validate. I understand that the DSP code may be totally useless (it’s only meant to be a gain plugin) but the thing won’t even open. Any suggestions? Even if this project isn’t salvageable in its current form, is there another way I can go about starting to write audio units?
