This has been stumping me for a few hours and I'm at a loss for a solution. &nbsp;I've been looking at working example code in the xcode debugger&nbsp;and have been getting the expected results. &nbsp;For some reason, whenever I try it on my own code, no formats are stored.

I have been declaring a private&nbsp;AudioPluginFormatManager called formatManager in my PluginProcessor.h file and calling formatManager.addDefaultFormats() in the first line of the&nbsp;constructor in my PluginProcessor.cpp file. &nbsp;When I step through the code, something I can't explain happens. &nbsp;

I put a breakpoint in the constructor, and also in prepareForPlay for my plugin processor and checked the debugger for each. &nbsp;At&nbsp;the first breakpoint, numAllocated and numUsed for the formatManager were extremely large integers. &nbsp;At the second breakpoint, they were both zero. &nbsp;I can't figure out what to make of this behavior. &nbsp;

I'm relatively new to JUCE, so please excuse me if there is an obvious answer to this problem.

&nbsp;

Thank you for any help! &nbsp;

You're probably looking at a different instance of the object the second time?

Thanks for the reply--I just solved the problem, but it wasn't that.

I guess there's something to be said for a fresh start on a new day. To fix this, I went into the introjucer and under the juce\_audio\_processors module for my project, enabled the JUCE\_PLUGINHOST\_VST option (I don't need the others at the moment). It was set to default, and that was preventing the proper areas of the module code from being run when I called addDefaultFormats()

Sure enough, this worked! Hopefully this helps anybody else running into the same problem.
