Hello list,
I installed cyclone through deken, and noticed that many audio objects are
missing: biquad~, etc.
Is this correct and have the objects been ported to another library? I use
cyclone in windows with no problems.
Best,
Joao
ah, but it's included in cyclone in windows? I imagine it's exactly the same object?

[biquad~] is a vanilla object.

I just checked, there was a [biquad~] object in cyclone 0.3-beta but it is not included in the final cyclone 0.3 release which you can find on Deken. maybe it was removed to avoid a clash with the vanilla object of the same name? the two are not compatible by the way. I guess Alex can tell if [biquad~] has been removed on purpose or by accident. Christof

Hi! Not quite exactly the same, but quite similar of course. This was an experimental cloned object that was didn't really make the cut for the stable release for a couple of reasons.
I think there are also other objects missing, are they going to be
included at some point?
what are the differences between both biquad versions? a neutral filter
coefficient is in cyclone 1 0 0 0 0, in vanilla 1 -1 1 -1 1. Are other
coefficients very different?

From the release notes of the "Release Candidate 1" version
"For this release candidate, we also deleted experimental and just "not ready" objects that weren't actual or good clones and needed more work, they are: [filtercoeff~], [biquad~], [cascade~] and [freqshift~]. These may be brought back into a final stable release later on."
But, to be honest, I think I'm personally done with cloning new cyclone objects, we did include quite a lot of new objects anyway, though...

They both take the same coefficients, but the syntax is different. In Pd it's *fb1 fb2 ff1 ff2 ff3* but in Max it's *ff1 ff2 ff3 -**fb1 -fb2*
This means you need to change the order and the sign of the feedback coefficients for them to be the same.
cheers

Actually, a neutral filter coefficient in vanilla is 0 0 1 0 0, if I understand what you mean by "neutral filter", which I'm assuming is just the input signal going out unchanged, using "1 -1 1 -1 1" works but it's just unnecessary, as you're cancelling out the coefficients. In the same way, you could, as an example, use the same "1 -1 1 -1 1" in Max's biquad~ and it'd work, as the feedback an feedforward coefficients are also cancelling things out. Hope I made myself clear...
very good, I never really used biquad myself. Then I'll adapt the patch to use the vanilla version instead.
