Ok so you draw three ramps, or you do a 3 channel chase first, so ramp in first one and then you shift drag that for 3 channels?
Then you put that into the clipboard with Ctrl-C, and then you do a shift drag of all the channels on that particular controller?
Then you can just shift drag over a few cells in the collapsed controller and it does a chase down all the channels as far over as you tell it with the shift drag?
I made my chases with a macro. i just drag it onto the layer with all the controllers I want, expand it to the size I want and done. if I want to change the color etc, I just right click the macro and make a new gradient (if you change a named gradient it changes in EVERYTHING as they are referenced from the library of gradients by name)
If I want to move it a tenth of second, i just resize it and done.
