@m_adam I still don't understand how to get the id of parameters? How do I know that this parameter has id 500?

Thanks for reporting I've created a bug report. Cheers, Maxime

Thanks @r_gigante that's what I thought.

@m_adam thanks so much for all your help on this!

Ahhhh thanks! I couldn't find an Array Manual in the R18 documentation. I was going like this: maxon::PointerArray<MyCustomClass> myPointerArr = NewObj(maxon::PointerArray<MyCustomClass>); DoStuffWithArray(myPointerArr); DeleteObj(myPointerArr); It seems my problem was with the PointerArray taking ownership of my pointers, then deallocating them before I was done with them. Since it doesn't seem that R18 has maxon::UniqueRef objects I decided to go with a maxon::BaseArray<MyCustomClass*> instead. Thanks again for your help Sebastian!
