Easy Step I find best for doing things I want a lot of control over. "Do this for this long, now do this for that long.... repeat that type of efforts until done" sort of stuff.
I like Easy Time for controlling movements on my movers, and doing more complex lighting stuff. For example, I have a scene where a moving yoke light just goes around and around in a circle acting like a beacon. I have others where they(the 2 movers) are doing what appear to be somewhat random sweeping, or back and forth movements, or circles. It seems ideally used for making FX.
In some instances, I engage the light early, setting the movement as a scene, then actually bring it "on" by having a switch open up the shutter. This way the light doesn't have to "snap" into action, it's already been placed.
I'm still learning this stuff myself. I just finished programming 2 large scale shows using Compu Show. One was much simpler than the other though. The first, I used Easy Time many times for movers and complex light color changes.
