So im using soundkeys to allow particles to move faster when there is bass in the music, i have achived this but the soundkeys expression i'm using makes my comp render extremely slowly past exactly halfway. The expression i'm using is linear(value,1,35,0.5,4.5) (under output 1) and i will link this to the physics time factor in trapcode particular. I know the problem is caused by this expression because i have disabled it and it will render fine. can someone please give me another expression i could use which will achieve the same result, thanks!

EDIT: The problem is caused when i expression which the physics time factor to the sound keys expression, does anyone know why this happens?
