We want sample accurate interpollation, but not a new control value per sample.
The controller is for control curves and those cause to high overhead if done
on sample level. Having a max controlrate of e.g. 50 Hz is covering already
exotic use cases. Most use cases would still be fine with 2-10Hz.
