Scrollers and Move on Dark

[drscoop]

Anyone know I how can I force a scroller to move on dark when it’s not a standard “‘lamp+1” fixture, but the scroller is a standalone fixture - and how to link to it’s dimmer channel so the desk knows when it is dark, if it’s not a straightforward patch?

For context, I’m helping out a new theatre group and using scrollers for the first time in an FLX S.  The rig has some pairs of tungsten fixtures wired back to the same dimmer channel, but the pairs of scrollers have their own DMX address, so I can’t use the multiple part standard fixtures as I need 1 dimmer channel but 2 independent scroller channels for each set of paired fixtures…

I am using the generic “scroller” 1ch fixture on the desk and can build colour palettes etc but can’t work out how best to patch this to link to intensity to move the scrolls on dark.

I kinda need a fixture that has 1 ch for intensity, but 2 channels, ideally individually selectable, for the two scrollers…  

Is there a workaround here?

Thanks in advance…
