AudioProcessorValueTreeState Improvements

Sure, I was just suggesting something that was easy to fit into the initialization list.

AudioProcessorValueTreeState::ParameterLayout createParameterLayout()
{
    std::vector<std::unique_ptr<RangedAudioParameter>> params;

    // Add your other parameters programmatically

    auto param = std::make_unique<AudioParameterInt> ("intParam", "Int Param", 2, 7, 5);
    yourIntParam = param.get();
    params.push_back (std::move (param));

    return { params.begin(), params.end() };
}

YourProcessor()
{
    // Do something with yourIntParam
    DBG (*yourIntParam);
}

AudioParameterInt* yourIntParam = nullptr;
AudioProcessorValueTreeState parameters { *this, nullptr, "PARAMS", createParameterLayout() };

The ParameterLayout also has a variadic constructor, so you could avoid the std::vector if you don’t need to add parameters programatically.
