Auval issues in tip

Audio Plugins

I got the following errors on the JuceDemoPlugin :


--------------------------------------------------
PUBLISHED PARAMETER INFO:
# # # 2 Global Scope Parameters:

it fails since the commit of december 29 ( https://github.com/julianstorer/JUCE/commit/ae8910cbcfa6cf7d0803344a4e57b579f21c54b5 )

Ditto.  Using Juce tip (7 Jan) + XCode 6.1.1 + OS X 10.9.5

Jules, can you please look at that sometimes?

This is caused by the AudioProcessor class having a empty AudioProcessorParameter array.

it validated correctly after implementing my parameters as audioprocessorparameter

Ah yes, I was puzzled by this, but that would explain it.

I assume this change would stop auval complaining (in juce_AU_Wrapper.mm, line 500):

    ComponentResult GetParameterInfo (AudioUnitScope inScope,
                                      AudioUnitParameterID inParameterID,
                                      AudioUnitParameterInfo& outParameterInfo) override
    {
        const int index = (int) inParameterID;
        if (inScope == kAudioUnitScope_Global
             && juceFilter != nullptr
             && index < juceFilter->getNumParameters())
        {
            outParameterInfo.flags = (UInt32) (kAudioUnitParameterFlag_IsWritable
                                                | kAudioUnitParameterFlag_IsReadable
                                                | kAudioUnitParameterFlag_HasCFNameString);

            if (juceFilter->getParameters().size() > 0)
                outParameterInfo.flags |= (UInt32) kAudioUnitParameterFlag_ValuesHaveStrings;

?

yes, thanks!

FYI I pushed a different change yesterday that should do a better job of fixing this.

I think that you forgot to push it on github. There is just an xml optimisation that has been pushed yesterday

oops, yes, forgot to push! It's there now.

Yup, works now with the latest tip - thanks Jules smiley
