Setting a base level in effects chase?

Right when I'm feeling good about my Hog skills a simple thing stumps me. I'm trying to set a base level in an effects chase and also never let the chase dip below that base level? Here's what I have done and failed. I have an effects chase running in one cue. simple chase with 50 par can chasing from one side of stage to the other with a small effect length so only a few lights are on at a time. I have intencity set at nothing and effect size set at 100. It's running just how I want it. The gaffer said I love now just set a base level of 30% so they are all on at 30% and never dip below that while the chase is going. I tried many ways to try to accomplish this. The best way was run another master with them all at 30% that worked but the problem is after the chase comes up to full it dips down to 0% momentarily. I tried priority, I tried writing it all in the effect cue and I can't seem to get it not to dip back down to 0%. How do you guys hand this?
Thanks in advance,

  • Richard,
    Let's start over.

    Effects are mathematically added to a parameters existing value.
    The Size of the Effect is added and subtracted from the effect.

    Example:
    You have Intensity at 50%.
    Applying a Sine wave at Size 10% would make the Intensity go from 40 to 60%

    So for your case you want the Intensity to go from 30% to 100%.
    That means an Intensity swing of 70%.
    Which means an Effect size of 35% (half of the 70% swing).

    But the Intensity has to be in the middle of that swing.
    30% + 35% = 65%.

    So,
    Set your Intensity at 65%.
    Apply an Effect like Sine at Size 35%

    Voila!
