The Function Profiles Oscillation command in the expression editor inserts the token oscil(<sf>,<ef>,<sp>,<ep>,<interp>,<sa>,<ea>,<interp>) at the insertion point in the editing pane. This token generates a complex oscillating function. Replace the dummy arguments as follows:
oscil(10,90,5,15,LinearInterp,1,20,SplineInterp)
Generates an oscillation that starts at frame 10 and ends at frame 90. The first half-period lasts 5 frames and grows linearly with the second-to-last half-period lasting 15 frames. The amplitude is initially 1 SOFTIMAGE unit and grows with a spline interpolation to 20.
