How to control the music in a base movie when different movies load into it

i want to know weather it is possible to control the music in a base movie when different movies load into it using load movie. it can done manually by using a volume slider. but is there any way to controll it using action script??

Suppose “start.swf” is a base movie with a music (xyz.mp3, event sound, 50 loops) in which different movies load in defferent levels. I want to controll the sound volumes differently when each movie loads & plays.

like when “one.swf” loads the volume = 50,
“two.swf” loads the volume = 0

thnx
