Trying to create pixelmad fixture

Using catalyst 4.4 under 10.6.8.

I'm trying to create a custom fixture that is basicly a set of knockoff versatubes already on a flying frame. The fixtures are RGB with no special control channels or anything. I have been using the 16 pixel RGB fixture in the past in excel to make maps, but I want a fixture I can grab and manipulate easier inside the pixelmap.

I have it sort of working, but it seems it's skipping or doubling pixels, and the first pixel somehow affects all the rest. If I drag the fixture so the first pixel alone is on top of a color in the mix window, the entire frame (every other pixel) goes that color. There is a control channel at address 1 on the universe that affects all tubes and tells them how many pixels to behave as, but all my custom fixtures are patched around that, and in the artnet monitor window channel 1 is staying at 0, where it should. Anyway, here's what I have so far. Anyone have a suggestion?
