It seems that many real-world applications will send 0 as the replay length, which was resulting in the behavior I was experiencing (nothing). It makes sense to interpret 0 as an infinite effect and therefore set the replay length of the effect to 0xffff. While the PID document does not explicitly state that 0 should be infinite, it does hint toward null values being interpreted as infinite.

Also, the formatting is weird here.
