I read that a real time kernel would be quite useful on a raspberry pi for pure data, and I wonder if this project would help:
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.
