I want to vary the pitch in realtime, and even to totally enable/disable
the pitch-shifting routines when needed, always in realtime, while rolling.
I'm not sure if all that's still linear. The CPU load of my process()
callback may remain constant when the user vary the pitch, but it will
suddenly increase/decrease if the user enables/disables pitch-shifting.
Is this still deterministic/linear ? If not, is spanning a new thread
the only alternative ?
