Hi! It looks like its not possible right now, but in the future I think it would be fantastic for there to be a way to use external effects. Or rather, a way for sample developers to include their own effects with a patch?
Maybe a way to host LV2 / LADSPA/ Nyquist plugins to take advantage of the libraries of free (sometimes legacy) effects out there? I know this kind of thing gets really tricky, as it would likely have to be compiled and self contained, and it probably wouldn't make sense to include any GUI elements either of course.
Would love to hear if something like this is possible! :)
