how do i make a windup and winddown like this?

14.7k RSH10Thunderbeam  one month ago

i feel like the wind up and wind down of my sirens sound really strange, since they both have the same interpolation and length. i wanted to have a short and linear wind up and a long and circular wind down, but i have no idea how. i tried using the car engine's RPM variable and it worked, but there was the engine sound even when the siren was at full speed. i want something that is coded with FT, so anything is appreaciated, + bonus point if you can make it run off of an activation group.

    @RSH10Thunderbeam Activate1 is the on and off switch, the output (which you can define as a variable) should follow the pattern

    with my limited amount of funky trees "knowledge" i'd expect something like this to work (AG1 is the activation group i used here):
    siren = 1? smooth(Activate1,1):smooth(Activate1,smooth(Activate1,1))
    .
    just copy paste this as a "siren pitch" variable and see if it works (i'm not confident but here we go anyway)

    @Axartar a matematical expression would be a lot better for this imo
    also can you make it run off an activation group?

    do you need it to be like a mathematical expression or smth else, because I could make it into a ft function if u wanted, not saying itd be clear or efficient but I could do it, so it repeats that periodically
