Sure... actually if I am ever to write synths, I would simulate some
existing (or non-existing) musical instrument... just for the sake of
sharing: I wanted to make simulators of folk/ethno southern italian
instruments (zampogna, ciaramella), but haven't found the time yet.

So, I'm not yet into that.

Yes, to me it seems very smart for the diffusion of LV2 to be the
first to get our feet into that.
