Question:
How do you edit the audio graph while the audio callback is running in a DAW? I read an articel that said you shouldn't do dynamic allocations on the audio thread. Are you supposed to allocate stuff on another thread and then atomically swap a pointer owned by the audio thread?

yes you want to avoid allocating on the audio thread if possible. better to allocate from the main thread or a worker thread, then swap it in. IMO doesn't have to be atomic, you can use a mutex, just want to make sure that any threads that hold a mutex (that the audio thread waits for) only hold it for a very short time (e.g. swapping pointers etc).
