depends...
you really have the same jitter when doing signal processing, and yet
you don't hear it.
(just hook your [metro 0.1] to a [tgl] -> [vline~] -> [dac~])

why? because [dac~]/[adc~] synchronize the jittery input data with a
real-time clock.

so Pd itself is accurate enough. the problem is that you cannot really
hook a number box to your stepper motor, you need some object that
translates the in-patch messages to real-world events. and this object
needs to properly handle the timed messages.

since ray did not mention how he gets the data to the stepper motor,
there is little additional help I can give.
