Optimizing Filter Module
Optimizing Filter Module
Hi community!
I have found this quite light and easy to use filter ( attached) yet from analyzing the LPF and HPF I see a slight resonance in the response (with Q = 0 ):
not sure which part of the code is responsible for it ... Can someone help in making it flat ? 
Also is there a way, since this is a 8/db per octave filter , to have a numberbox where we can insert how many db/octave we want ?
(I think that'd be pretty cool and make it so much more flexible
)

Re: Optimizing Filter Module
For flat response search for butterworth filters (here and SM forum).
Need to take a break? I have something right for you.
Feel free to donate. Thank you for your contribution.

Re: Optimizing Filter Module
I was peeking for some similar filters and how to change the db/octave thing , yet I couldnt find a specific LPF and HPF along with a db/octave option wich Is the main module I need 
, I hope this is something you or someone can help me with ! thanks

Re: Optimizing Filter Module
This looks very much like a Butterworth, Im on the older synthmaker so cant check.
But, the response has a little bump because its a 2nd order filter, so you have to delete the suspected "highpass" section and youre good to go. Seeing this.. I would actually prefer this one over whatever you make of it but thats a matter of taste I guess. Also you can see if the resonance parameter has a setting other than 0, and set it to negative or zero.
