Attached Controls shouldn't send notification on setValue()

It’s not necessarily you, it might be the host, so see this thread:

Reminder: AAX setParameter is asynchronous -> use locking

Hi everyone, I just spent the last 4 hours hunting an extremely non-deterministic memory corruption bug in my plugin. The root cause was that Pro Tools 12 will call setParameter on an automation thread while processBlock is called on one of their audio processing threads, which in my case lead to memory corruption inside the parameter class. The resolution is super easy: Make sure you lock the callback lock in setParameter, e.g.: const ScopedLock sl (getCallbackLock());

…mind that the discussion continues, the solution of the first post using locking is not recommended…
