Add Note Track - Autodesk 12812-051462-9011 - 3DS MAX 9 COM LEGACY SLM Help File

Linear Projects the animation value along a line tangent to the function curve
at the end of the range. Use Linear when you want the animation to enter
and leave the range at a constant velocity.
Relative Repeat Repeats the same animation as within the range but offsets
each repetition by the value at the end of the range. Use Relative Repeat to
create animations that build on each other as they repeat.
