Hi,

I've had a report that the AU version of my plugin 'Gater' fails AU validation in Logic Pro in OS X 10.6.8. Is this the same validation that is performed by Apple's 'auval' tool? I ask because I've been unable to get auval to even register the existence of any of my AU plugins, or any other third-party AU plugins. If I type:

auval -a

I get a list of Apple plugins and nothing alse. My AU plugins run fine, as far as I can tell, in Garage Band, Reaper, Studio One 2 and AU Lab - two of which are made by Apple! I've used Symbiosis's method 2 to port the VSTs over, i.e. copying the VST to the pre-built component package.

I've come across this issue before myself. No, Logic's AU validation is not the same as auval. I'm not exactly sure of the details, but Logic is even more picky about validation than auval.

I tested the plug-in out, and it does indeed fail validation. Here's the report from Logic:

Code: Select all

PUBLISHED PARAMETER INFO:

# # # 17 Global Scope Parameters:
ERROR: -10879 IN CALL Parameter Value's String
ERROR: -10879 IN CALL Parameter Value's String
ERROR: -10879 IN CALL Parameter Value's String

* * FAIL
--------------------------------------------------
AU VALIDATION FAILED: CORRECT THE ERRORS ABOVE.

validation result: failed validation

Hope that helps.

Thank you. At least it gives me some idea of where to look. I wish I could get auval to work, though.

Since your AUs seem to work in GarageBand, AULab, etc., do they pass validation using "auval -v" after you build the component (in Xcode I assume)?

I'm not quite clear on what you mean by auval not working.

Weird, because auval -a lists Gater just fine at my end (on Mac OS X 10.6.8 ).

BTW, it reports the same failures as Logic:

If I enter: auval -a, I get only Apple AUs listed,

If I enter: auval -v aufx SPCg SPCP, I get:

ERROR: Cannot get Component's Name strings
ERROR: Cannot get Component's Info strings
ERROR: Error from retrieving Component Version for resource: -3000
FATAL ERROR: didn't find the component

If you're thinking that I don't know how to use Terminal, you're right (-;, i'm basically a newbie on OS X. BTW, I'm also using 10.6.8.

With regards to the actual problem reported with my plugin, I think I've tracked it down - another one of those "doh" moments )-;

According to the auval output above, your plug-in's class is "aumf", not "aufx", which is why auval can't find it when you type in auval -v aufx ...

Also (I'm sure you know this, but just in case) make sure that your component is located either in the /MacintoshHD/Library/Audio/Plug-Ins/Components or /Users/<username>/Library/Audio/Plug-Ins/Components folder. You can have Xcode automatically copy the built component to the appropriate folder in Build Phases.

I don't think this is the problem as I tried both "aufx" and "aumf" - I've changed it to "aufx" now because I've removed MIDI reception from Gater and changed the appropriate field in .r to "kAudioUnitType_Effect", but it didn't work previously with "aumf".

Yes, I've tried it (and my previous AUs) in both these locations but it doesn't make any difference. None of them show up and neither do any third-party AUs. I've just tried [as I type] installing a third-party AU, restarting just-to-make-sure, running Terminal, typing "auval -a" and the only thing I get is a list of Apple AUs. I'm sure I'm somehow using auval wrong...

I'm going to try bumping this because I've made no progress with this problem: I run Terminal, enter auval -a and get a list of Apple AUs - no third-party AUs appear, including my own. What am I doing wrong?

quikquak · Post by **quikquak** » Fri Mar 07, 2014 5:01 pm

The names are case sensitive BTW, it's caught me out a couple of times.
Also your resource version number has to match everywhere in your plug-in. So maybe 'kVersion' has two different values in the resource file and elsewhere?

How are using Symbiosis? What method are you using?

SPC Plugins · Post by **SPC Plugins** » Sat Mar 08, 2014 2:20 pm

Thank you quikquak and yeahtuna: After doing some more experiments this morning it seems that the problem is (somehow) to do with my Mac because if I try the same command line calls on a different Mac my plug-ins appear on the list along with the Apple ones and validate without any errors. My auval appears to be faulty...

Is it a 32 vs 64 bit issue?

SPC Plugins · Post by **SPC Plugins** » Sat Mar 08, 2014 3:14 pm

32 vs 64 bit? I've no idea. My Mac and the other Mac I tried are both 64 bit, my plug-ins are 32/64 bit. I think auval defaults to 32 bit mode but I'm not sure how that affects things - I used the same "auval -a" command on both Macs followed by the same "auval -v aumf SCgp SPCP" command on both Macs. Mine doesn't work!

yeahtuna · Post by **yeahtuna** » Sat Mar 08, 2014 6:33 pm

Maybe you're system is looking at a cached version. Have you trashed you're AU cache?

Apple's 'auval' can't see my Symbiosis-ported AU plugins.
