Thanks a lot for your detailed answer! But actually I wasn’t too clear with my question probably
I know how to multipatch a fixture and use it all the time. So let me try to explain better.
When I get to a new venue, I unpatch all my fixtures first. Because most of my fixtures are multipatched (that makes it easy to have a stage wash no matter if its 2 or 8 fixtures, depending on the size of the stage) I then have them in the area below the dmx adresses.
In Vista 2.3 it was possible to grab just one of the fixtures to pull it up to the dmx adresses. in Vista 3 it selects all the multipatched fixtures at once. So if you already patched fixtures in between the field of the for example six fixtures you pull up, I then have to move them to a free area first, before I can then pull each single fixture to the adress I want them at.
Perhaps this helps to understand my question
