This is fantastic opcode! I don't see it that much in the examples
but sound quality is very good. I highly recommend to try it out.
And it has parameters that slightly change the character of the filter like setting 
up the mode and choosing the number of poles.

Cheers,
Anton

Oh whoa. Didn't know csound had elliptical/chebychev filters. Nice.

Thanks for mentioning this Anton, I enjoyed exploring it today.
Elliptic filters are not implemented in the code; perhaps someone
could give that a go.

For those that might be curious about the various filter modes,
Wikipedia has a nice graphic in the entry for Elliptic filters:

https://en.wikipedia.org/wiki/Elliptic_filter#Comparison_with_other_linear_filters

It gives an idea about the tradeoffs for what you get in the pass-band
versus the rest of the bandwidth.

I've started to explore csound filters since I've read somewhere that the filter 
is the most important part of the synth. The filters define the character of the synth.
So I'm trying to understand what characters Csound offers.

I see that rezzy is good for pads it has very mild ad mellow tone
the lpf18 is good for leads if you want the signal to sound really bright.
lowpass2 has interesting wobbling effect. It's very sensitive to resonance.

clfilt sound a lot like virtual analog filters like new ones re-implemeted by Rory
it's has very low demand on resources.
