Forgive me if this is extremely newbie or anything, but when I try to set a line's grain rate with a creation argument in pd 0.36-0, instead of setting the grain rate it seems to set the current value to whatever you type there. When you nest send a pair of numbers to line, it begins at this number specified in the creation argument. . .
Ok, I figured this out. Apparently, there are two possible creation arguments, first for an initial value, second for a grain rate.
Attached is an amended help patch.
