Heh :) Well, right now, I'm more wondering about what ui:AndroidUi could be.

Aside, in the ui ext docs there's this example which contains ui:binary, but I
can't find any reference documentation about this binary property on the page:

Effects are not the top priority. I've done quite a lot of research on it
because it was a good topic for my intern to work on. I have other basic
features to add first. And the schedule that you mention makes sense to me.

Hmm, I've been wandering in google yesterday about such LV2-LADSPA bridge.

I am discovering the NASPRO project. That's interesting. It seems like it may
consume a lot of brain-time diving into all this when compared to LADSPA. But
I'm nevertheless a bit worried about adding support for LADSPA, as it's getting
old and somehow obsolete. But IIUC correctly you are about to add some sort of
LADSPA backward compatibility, which in any case, sounds very good and was
clearly missing.

What kind of help would you need?

Also, are you/is there anyone on the list who is interested in releasing audio
plugins for Android? Feel free to write me personally if needed.
