So, about "Hoa", we should try and make it available for vanilla via deken as well. I wonder if others managed to compile it and use it so we could upload these, or just interested. The available downloads in that repository do not work for me and there are known issues running this in newer versions of Pd, for more, see https://github.com/CICM/HoaLibrary-PD/issues/13

On a related note, CEAMMC offers a modified version of the HOA library as part of their system.
