Magic 260 and Design Spots 250

I am more like a beginner in setting light show but cannot understand how my problem can be solved.

I set all the channels inside each lighting ( at least I know how to do it

In magic 260 - lets say I have programmed 3 lighting scenes.
#1 Moving heads are directed 90 to the letf
#2 Moving heads are directed 90 to the right
#3 Moving heads are directed all the way to the back


I'd like to program a lighting show for instance:

From scene #3 heads go to the scene #1 ( total time 5 seconds) then
from scene #1 (lights are already here) to scene #2 a little faster - let say 10 seconds total then
from scene #2 to scene #1 in 15 second total scene time.

I would like to create someting dynamic with various lenght of time amoung scenes.

How to do it with magic 260 and moving heads

All I can program is the show which have even lenghts amount scenes.


Please help.
