The rate at which [line] outputs an update of the current value. I'd probably call the second argument "grain period" as "grain rate" implies a frequency. > Specifically-- if the default grain rate is 20ms, what does that mean > for > the schedule upon which [line] will output messages over the course > of > a given ramp's duration? I'm not sure I fully understand what your asking. Upon receiving a two- float list, [line] starts sending out messages at the given rate. The time period between the message reflects the second argument, except for the time period between the second to last and last message where the period might be shorter so that the sum of all grains equals the ramp time given.
