Shutter control (by fader)

[Hans]

Hi,

How can I control my shutters by fader?
For example, I patched a strobe, then I  set my dimmer to a playbackfader, but how can I control my shutter (=speed) in live situations? 
I prefer to put it on a fader or direct action by an encoder in playbackmode.

Now I changed the shutter in "dimmer2" but that's not ideal and the right way I guess. 
Is there a solution?

ps. The same for al the shutters... e.g. moving heads.

save a cue with a value of 255 for shutter. link the cue to a fader and set the fader to infade. now you can control the shutter with fader.

Thanks it worked after several times to try.....
I couldn't fix it, without an important thing, I din't noticed before.
I saw later, that several fixtures in the libary, have the shutter on snap instade of fade and than, it doesn't work. Correct me if a'm wrong.
