If you can send me an email with a single post where I did this, I will formally apologize for all you believe I did to you.
I'm not talking about you directly, i'm talking about the cross section of people who are constantly buzzing around like flies who do it.

You do have a habit of sticking your oar in where it's not wanted though Urs, you've proven that on a number of occasions, unless you are the centre of attention you really aren't a happy bunny.

Why do you think I dumped your synths so quickly ? Not only are they of no use to me, but i'd never support a developer quite as two faced as you are.
can you show any proof of this?
anyone can make unfounded accusations, without proof though its just hyperbole.

Just read this thread back, if you need immediate proof. Discussing something technical isn't an issue, in fact that's what I thought this thread was about. I could direct you back to the Saurus thread, but even i'd not expect someone to trawl through 100+ pages of avoidable bullshit.

Can play the "lets keep it cool and OT" card enough times to then make it something else to be branded 2 faced in my book.

That's my line of thinking for posting it. More specifically I don't think it really invalidates any of the actually modelling you or anyone else is doing, even if it could be combined with such work (I've yet to try it with truly problematic circuits).

When it comes down to actual modelling, my line of thinking is that there are two separate sub-problems: actually modelling stuff as differential equations (or other forms of math) and computing real-time discete approximation of the former. I only really wanted to try to contribute to the latter and I think it's quite possibly the easier of the two. If my method holds together as well for more complex models (which remains to be seen) as it does for simple ones, then hopefully it enables people to use more accurate models by reducing the pressure to simplify.

I'm also specifically targetting people that wouldn't go for 0df because of the cost of iterative solutions. Basically I'm hoping we can at least transition from "linear euler with fudge-factors and a saturation in feedback path" stuff to "0df solution with reasonable approximate for the saturation in feedback path". Both models are really horrible, but at least the second one is a bit better IMHO.

Seems like an open question but, on the hunch there's some really usable qualities of s-plane stuff that can be seen as independent of accurate emulations, well worth exploring IMO. Certainly good karma to have posted some code!

I don't like doing this but LeVzi must take a week off. If there are any more personal attacks the thread will be locked.

People, be kind to one another even if you have a disagreement. All we've got is each other.

I've been meaning to try out some of your stuff!

insulting user should be banned

KVR will be a better place without them

KVR will be a better place with people disagreeing but still behaving with consideration -- arguing facts, not lashing out. Banning anyone but spammers and irredeemable trolls is no pleasant or positive thing. Several gentle warnings went unheeded, so I felt it necessary. Back to the topic now, please.

How big is the quality difference between a "normal" filter, just for example basic ladder 4-pole lowpass, compared to one which is also a ladder lowpass but with zero feedback delay?
Logical on the same samplerate & oversampling settings

Is this difference really so big? If the difference would be only small, the question "would it be worth it, through the higher cou usage?" would very vaild.

My understanding is that (especially with the non-linearities, intuitively I want to say necessarily with them) it turns out that the difference is precisely impossible to analyze easily, the behavior becomes very complicated, Mandlebrot kinds of stuff.

Very nice sound example. I may have to give Corona a try.

But wait, do they use dongles?

That's what they always say, ye of little dongles!

It doesn't matter how full of licenses a dongle is at the beginning; it matters how much fuller it can be! My three are growers!
