Just wanted to say that I did not know about this opcode until today.
It sounds amazing! I'm so glad to have found it.

Thanks Victor.

Best,

Peiman

I've seen it before in the manual, but I thought it's only useful if you 
need all four filters, or if you need somewhat better quality. Is it 
really that much better?

You took the text out of my finger tips. Surely it'll only add
overhead unless you actually need all four filters? Ok, overhead is
exaggerating it a little but I guess you know what I mean..

I am not running out of CPU here.

And I do need all four filters. But honestly, I don't think the
overhead is that much. It does sound so superior to the other filters
I tried in Csound (must be the oversampling).

To be honest, I didn't expect the overhead to be at all noticeable.
Your remark that it sounds better than the other filters you've tried
in Csound intrigues me. I'm assuming you tried your fair share of
Csound filters!

Well I am just judging by my ears and the very limited experience, and
of course the nature of the sounds that I am putting through the
filters and the manner in which I am changing the filter parameters. I
tried the following filters just today:

Butterworth filters
atone
svfilter
bqrez

I also really like svfilter. But it seems that statevar is more stable
for my purpose.

I would be interested to hear about other filters that I have missed
and that may give me similar results.

Thanks

I agree that statevar sounds good, as does svfilter.
As each filter type has it's own characteristic sound, it might be a
good idea to revisit the different filter types now and then.
But of course one will more often come back to one's favourites.
The one safe bet for me is the lpf18, as it's warm and resonant with a
nice distortion.

I'll give it a try then. I've examined a lot of other filters in CSound. 
I've read that the nice sound of analog synthesizers is due to their 
non-linearity, while most filters in CSound are linear. The only 
exceptions that I know are moogvcf, moogvcf2, moogladder and lpf18. I 
tried these to simulate the Korg monotron using a sketch posted here 
recently. I liked the moog filters most, lpf18 was in between these and 
linear filters, but none of them sounded as good as the real thing.

I shortly experimented with a free VST in another application, that did 
filtering with resonance on square and saw waveforms, which sounded 
better that the filters of CSound. Does this mean that CSound lacks a 
good non-linear filter? Or maybe I just didn't find the right 
parameters, although I tried a variety of parameters?
