[sdiy] Digital ADSR - perceivable staircase?

[Matthew Smith]

If we consider a digitally-generated attack signal as a staircase, at 
what 'width' of step - in other words the time between increments in 
level - would the increase in volume of the system output become noticeable?

So as to have something to go on, I am considering a maximum A/D/R time 
of 2 seconds so, at maximum time, a 'step' would be about 8ms long, 
based on 256 levels x 256 steps.

Really wondering what my maximum time can be before the 256 steps become 
obvious.
