When i apply a 1% velocity envelope to a 1 seconde clip, the looping notches should be at 100 seconds. I never get this.
And, i never get the same value ( 52 to 92 seconds).
How are you setting the velocity? If you are moving the line with the mouse you may not be hitting exactly 1%. You might be getting 1.080696% which would result in 92 seconds, or 1.923077% which would result in 52 seconds. Try right-mouse-clicking on the node and typing in 1. This should set the velocity to exactly 1%.
