Re: [PD] Cycle~ difference with Max5. Was: Update cyclone maintenance

Hi Alexandre,

So, hey Fred, would you be able to get into sourceforge and close all the bug reports that have already been taken care of?

I'm not sure how to get in it and do it. I guess I should do that to cause I'm aware of a few things that are going on, so if anyone could tell me how to do it, I'd like to try and collaborate.

IOhannes changed the policy, so any registered developer can close issues. I already started closing some of which I was reasonable sure they were fixed. Some others, I want to check first.

Moreover, still about [cycle~], I just wanted to make sure it behaves exactly like it says in Max 5 documentation. They descibre how it needs a table with 513 points, and that the 513 needs to be the same as the 1st because of the interpolation (I assume it does a simple linear interpolation then, right?). In the case of a table with 512 points, [cycle~] will add a 513th point that's a copy of the first. Anyway, this is what it says in the documentation and I'd like to check with you if it's working exactly like that as well. Perhaps you could mention that too in the help file.

Yesterday, I updated the cyclone binary distributions at http://puredata.info/Members/fjkraan. The simplest way to install the correct one is using the deken-plugin: https://github.com/pure-data/deken. If you use Pd-extended, you have to rename or remove the original cyclone directory, to prevent having two cyclones.

Indeed, simple interpolation is used. From the cycle_perform: *out++ = f1 + frac * (f2 - f1);

I replaced the core of the cycle_gettable, and in case of an external array, the 513th sample is copied from the first.

I do not completely understand the Description of the Max5 cycle~: when should I make the 513th sample the same as the 512th and when should I use the first? The latest implementation always uses the first.

cheers

collected all bug reports related to cyclone. It'd be good to
commitor close/mark as fixed.

    another report for [rand~], by the way, maybe you should get
    involved here and mark them as fixed

            About the sample-offset, I have some problem
            understanding how it works,
            and have to change it anyhow to fix the issue
            (garray_getarraywords
            related on 64-bit systems). 


        seems there was a bug report about this :)
