Maybe there's a confusion between real-time priority (standard kernel)
and hard real-time (RT kernel).

Hard real-time is more for really time-critical stuff down to 
microseconds, like driving a CNC or stuff. Having a real-time task
running can feel like your computer is super-slow. It's more made for
single task processing.

As far as pd is concerned, I'd say real-time priority is
enough, and is configured with /etc/security/limits.conf.
