hi
i’m not sure if i understood it correctly but here we go.
I would put all three instances in a seperate layer.
//expression for position
driver=thisComp.layer(“sound key layer 1”).effect(“Sound Keys”)(“Output 1”);
po=random([0,0],[thisComp.width,thisComp.height])
if (driver>55 && driver<60) po else value
//end of expression
What does it do?
if the Sound Keys-Output value is between 55+60,this expression will position the instance randomly within the comp!!
i hope it helps
