I am programming a strobe effect for a MAC301. When I program it in cue mode (i. e. LIVE), the ML Controls shows a column "Shutter Strobe :: Strobe" whereas when I try to put the same thing in a Preset or Beam Palette, this column is missing and I see only Shutter Strobe. The Blind display shows "Shutter Strobe" and "Strobe M" for both. Why are they different? How do I relate these to the actual ML DMX channels/values?
