Very nice!
In 'planifolia' (in deken) I have created some abstractions to deal with arrays... not so many things, but there are two nice abstractions to create dynamic-patch based operations with arrays ([array.binop] and [arra.unop]).
Not related: Would it be possible to you to upload a git repo with the last update of timbreID-examples? The link to your page is broken! I was trying to show the timbre-space example to a student and, as moved from mac to manjaro, I'm not sure if the bug I'm having here is related to my system, to the verion of the timbreID-examples pack that I have or with some sort of bug.
Thanks again for your externals! :)
