working on idea using for now translate Y this expression If(Mod((ChorTime()*30),5)=0,Rand()*50,100) which keeps the model at 100 except every 5th frame takes random value this might be used to keep color for x number of frames then put a new color in to the next x number frame if values stored in null ...getting late will try more later

Mod gives remainder and division by set number so here ChorTime()*30),5 = 0 every 5th frame
