Loading banks increases memory usage in the default memory pool. Note that each bank uses a different amount of memory. Memory used by a bank in the Default memory pool does not depend on the physical size of the bank but on the number of sounds and Events that it contains.

Some effects, including reverb and delay, consume a certain amount of memory in the lower engine pool when playing.

Playing multiple sounds at once drastically increases the amount of memory used in the lower engine pool.

Sending multiple actions in a short amount of time increases the memory usage of the default memory pool.

Registering game objects, setting 'per object' parameters, and setting object positions all use a small amount of memory in the default memory pool. Be aware, however, that unused game objects must be unregistered to free up this memory. Otherwise, the amount of memory being used constantly increases.
