dynamics

I'm not sure what you mean by "symetrical circle".
There is a Circle dynamic effect in each direction, and a "Figure 8". Are any of those what you mean?

Dynamic Effect Playbacks behave much like channels, and accept all the same timing adjustments that channels have.
They'll follow the In/Out time, Channel Time and Per-attribute timing as desired.

There are a few tutorial videos here that might help:

See near the bottom for videos about Effect playbacks.

yes this is a dynamic circle
you know , like in granMA2( circle wing 2 and pan wing -2)

i have six viper on a truss 1 thru 6
i want 1 and 6 together but pan mirror, 2and 5 same, 3 and 4 same
and tilt offset between 1/6 and 2/5 and 3and 4
( 1and 6 same tilt ,2and5 same tilt,3and4 same tilt)
