In other FMOD functions that return a string, the length of the string is always passed back as an optional argument (like `Studio::Bank.getStringInfo`) but `Studio::CommandReplay::getCommandString` does not do this. I’m wondering why this is the case?

Hi,

There isn’t any specific reason why they return a different result. They were just designed differently.

Hope this helps!
