Hey. How's it goin? That Stand alone button is exactly what you need. When we make profiles, if the fixture has a DMX trait that lets you place the fixture in sound active mode or "Stand alone" operation, we place it too that button. So you can simply hit that button and the fixture will then ignore all the other DMX commands and do it's own thing via the mic on it.
"Phas" is Phase or Phasing. Say you have 4 moving heads and you select circle, all four will be at the exact same position. but if you "phase" or offset as some people call it, each fixture will be slightly ahead or behind of the one before it and after it, depending on how much phase you use. Think of it as a tilt wave you see at most concerts. That would just be all fixtures going up and down but because of phase, you get that wave effect. Cool?
Let me know if you have anymore questions.
Sincerely,
