What makes a good filter?

After trying alot of the software synths out there and a hardware synth that i have (A-station) it's obvious how damn important the quality of filters (lowpass, highpass etc.) is. I'm just wondering... what factors make a good filter??

 

I originally thought it was a simple eq device rounding off frequencies below a certain point in varying smoothness depending on the resonance. But this cannot be true, or how do different filters have such a different effect from each other? Correct me if i'm wrong but i just don't think it's the purely the synth that makes the difference.. and i've heard people going on about how sick the filter is on the nord etc.. can anyone shine any light on this? thanks!

maybe i can explain..

 

On a digital synth as nord lead. the filters depend on a well written algorithm (code)... and if its heavy written algorithm.. (lots of coading) it will also need a good cpu (processor). The steepness of the filter is also important, a filter cuts everything below or between or over a sertain frequencey. a EQ only lowers or boosts a frequecy (plus frequencys around it).. If you have a very steep filter it they might not sound so good if they are not well written.. so thats probably it, the reserchers at clavia is probably kickass programers.. a filter you get with a software synth doesnt have as heavy filters as most hardware synths..

on a analogue machine the filters depend on how much the components can take..

 

hope this helps, or maybe it just makes things go round more in your head!:)
