yes Sytse, of course - not much difference to other equipment - somehow :-)
But my impression by wording was, that whatever you designed the sound to (all you mentioned and more) one just turns the knob and gets a complete change of "speed", similar to if the PB is master, but as slave.
Something I have never heard of it would be even work, without dropping synchronization, jitter or other unpleasant effects.
OK - whatever, I just thought I miss something.
