[PD] add or subtract value every N ms?

[Andy Farnell]

But this is better :) If the limiter is on the output then the counter continues
beyond the 0-127 range and goes out of bounds. Putting [clip] (same as min and
max together) inside the counter locks the value in range.

What's the best solution to prevent overshoot? I did solve this once before
but it used spigots and was ugly imo.
