Thanks James, I got to that point. The fade values are 128 to 255 on channel one. I set my first DMX level to 128 and last to 255. When I add the fixture in myDMX channel one starts at the bottom at 0 and ends at 255. If the slider is all the way up and I click below it the slider will return to the 128 level as almost a bookmark. But I can't drag the slider down without it hitting below 128 and then the light flashes.
Also, looks like you're a developer, any way to double click or some other shortcut to take the slider right to the top or bottom?
