Ok went through all of these.
fluid.dataset~ “audio-descriptor” and “merging” tabs pours off patch size:
There’s also some inconsistencies/weirdness with fluid.noveltyfeature~ / fluid.noveltyslice~ with @maxfiltersize, but I don’t think these are 1.0.9 related.
So it seems like @maxfiltersize cannot be changed at all, as an attribute. You need to set it as an argument. I guess that’s a Max quirkiness thing where you want to be able to set it as an argument and an attribute.
A more solvable thing is that the default settings and the attributes set in the fluid.noveltyfeature~ mean that it is not possible to adjust the filtersize attrui. This was super confusing and sent me down the rabbit hole of maxfiltersize, but looking at the helpfile for fluid.bufnolvetyfeature~ I can see that more comprehensive attributes have been set, which means you can adjust filtersize in that helpfile. So my suggestion with this whole long rant here is to adjust the @maxfiltersize in the fluid.noveltyfeature~ helpfile to be something > 0, especially if you are going to expose the filtersize as an attrui for the user to mess with.
