Controller lowpass filtering

SubjectController lowpass filtering
Hey hey everyone,
I'm still working on my oscillator and want to eliminate the additive 
synthesis to construct the sawtooth and soft sawtooth.

My idea is to create a clean sawtooth wave and use a lowpass filter to lower 
the harmonics. But I'd need to know the exact behaviour of a filter. Sawtooth 
harmonics decrease in volume as 1/n. My soft sawtooth has harmonics decreasing 
at 1/n^2. And of course the sne has no harmonics.

So is there a filter in Csound, that I can use to achieve this effect, if 
corrleated to the basic frequency of my oscillator? At which cutoff frequency 
would it lower harmonics by 1/n and at which frequency would it only leave the 
basic frequency (the first harmonic)?

Or should I use another tool all together to achieve this effect?

I'm grateful for any suggestions, especially since it's "World gratitude day" 
today. :)
