17. Highlight the X Posit ion track, and then
right-click it and choose Properties.
This reopens the Float Limit Controller dialog.

upper limit on the graph become smoother.
Note that there’s an upper limit to this value; in
this case, it’s 34.434. This limit is determined
by the va lues of the other three settings on the
dialog.
19. Try increasing the Lower Limit group >
Smoothing Buffer. It’s not possible with the
upper smoothing value at its maximum.
20. Decrease the upper smoothing value, and then
increase the lower smo othing va lue.
Now you get smoothing at both the upper and
lower limits.
