hi, 

when I patch fixture in BASIC mode, you have, on channel 16, crossfade from Colour (basic fixture) to pixel engine fixture.

I did patching by selecting main fixture and in Design / Selected Items I did patch pixel engine fixture.

In Chamsys when I go to modify that channel 16 to go from Colour to Pixel engine nothing happens. 

I have to put all colour info to 0% in normal (basic/colour) fixture, to have control over Pixel engine. Othervise colour mixes with both colour information.

In real life when channel 16 is at zero, fixture works in normal (basic/colour) mode, when that channel is at full than fixture works in Pixel mode, and also crossfade works (it is not snapping from normal to pixel mode).

I will apriciate if you fix that bug.

Thank You
