I don't quite understand what you want. There are two main transition effect controls: 1. Transition Select (the pop-up menu that allows you to select the transition, e.g. Dissolve, Grid, Strobe, etc) 2. Transition Parameter Knob (the control that affects the currently selected transition, e.g. control how fast the Strobe transition strobes) Do you mean that you want the transition to randomly adjust the Transition Parameter Knob?
