Is there a way to make a scene in steps or even generator editor - and later - inside 'LIVE' - to have a fader that gives you an ability to expand or decrease the X & Y values - so it expands or reduces the moving radius, depending on your raising or lowering of the fader.
I've seen this possible with ONYX software by Obsidian Control.
No this is not possible in "Live" (real time) because our Generator concept is different.
In generator, we draw the entire pan/tilt movement, so expand/decrease this movement raise some questions without logical answer like based from what point.
FYI, with our software V_II, it is possible to add one Generator movement to another one. This is not what you are asking for, but we just inform you because this is a nice feature.
