Hi Paul,
I believe most call that exposure time, not gain. I believe their naming
creates confusion.
BTW, why would the stepper motor pitch change (if you mean pitch as it
relates to distance, not to sound...if it relates to sound, then, well,
forget I asked ;-), which I assume, means it changes resolution?

Austin
