I have been looking into the code on the Moog filter example in the docs, I know nothing about coding but seem to be able to follow it, One thing that puzzles me is i dont see anything being passed to the output ? Am i mental or is this so ?

tou shoud find a like saying somethin like
out=out4;
This one the one that puts result in output

I think im going blind, I didn't even spot that before lol

Small question about code components, If i was to create a filter that i wanted distortion on, Would there be any CPU hit by putting the distortion part into a seperate code component for ease of editing and reuse ?
edit* I dont suppose anybody knows where i can get some DSP nfo on 18db filters (ala 303) ,I've checked at MusicDSP but the only ones they have there are for Sinc C and i just dont understand that at all, I was thinking of looking in the source code for Creakbox which i have lying about somewhere but if anyone has any better ideas 🙂

I just found a text file with the Creakbox source that is called IIR, This would be the filter yes ?

Yes IIR is the alias for "Infinite Impulse Response Filter". They are the filters you usually found in SM ( at least by now)

You can make a 18 dB filter by statcking (applying in series) 3 Standard 6db filters. At least in theory. Anyway what make unique the 303 filters isn't the 18 dB but his Auto-decaying of resonance. Specifically his negative exponential decaying of resonance. I thin, until SM get more math primitives, better to start with standard IIR and Biquads, or use The SVF provided by stefan ( look at examples forum ) or play with the karlsen 24 db provided ( still beta) by myself

I used to use a 12 and a 6 in SE to get an 18, Even though its not just the poles makin the 303 filter i actually prefer the sound of an 18 to a 24, I know strange but true 🙂

How far is csound from the code component language ? Whyterabbyt has put me onto a load of 303 Csound stuff but it looks further from the code component than C++ ?
