FX Masters do not work at 5.
I reassign the presets to the desired FX Master, everything works. Saving the show file. I restart the program-it doesn’t work(((
I am not following your description.
Can you please submit a support request with a copy of your showfile and a short video of what you are seeing and we will happily take a look

An update on this @Sergey.
We have found that they DO work if you restart the Vista application and then load the showfile.
We will continue to hunt for the problem and fix the issue, but in the meantime at least you can program and load your shows as normal (after a restart)
