Since this was posted, I went ahead and created a scene that blacks out my lights. I edit it needed to include the lights that need to be blacked out. I also have different black outs for specific fixture groups and one black out for everything. So this part works fine.
I have also assigned blackouts to buttons on my midi controller. I have an Akai MPD16 and an Elation Midicon. It works, simply put.
...but I have noticed that the black out speed is a bit slow. When I press blackout, I want the black out to pop, not fade. I am pretty sure its not a performance issue with my computer, because I have tried it on various computers, even my new Lenovo that I just bought a couple of weeks ago.
Is this just a midi thing?
