I would say the operative word is "Growing." Markus has certainly tried to get the Mellotron sounds out there, but I am not aware that he has created or gathered many new sounds. Surprisingly, he isn't going after the torrent sites that are giving away the Mellotron Archives CD. He should.
I think that there has been huge support for growing the Streetly library and there are some amazingly great sounds to be found there.
