Inventor of the PlantMusicProgram and the program for the PlantWriting  are Harald Finke and ArneTraumüller.
The idea comes from the artist.
The algorithmus for PlantMusic and PlantWriting is programmed by  Arne Traumüller, based on the program Orakel of Ole Traumüller.

comment: ..if  you compare the new digitalised results with the old analog results,  then are the earlier more symphathic - I think.  A sinus-sound for an example is more adequate and  more real then the new  abstract PlantPiano.
answer: The sinus-sound has naturaly his significance, but compared with the piano-sound it is not more real as the sinus-stuff. Importent for me is the installation of an artforum for finding signs. This forum shall serve the living plant.
question: What do you mean with install a forum for signs?
answer: If it is painting, drawing, sculpture, text ore music - all of those levels will try to find or create language. This forum is a forum for expression and communication. And as an artist, it is importend for me, that the expression of the new sign is useful. I dont only ask, how near comes this sign the reality? For me it is more importend what it means or expresses. Therefore I like the pianosound. It is directly connectetd with the impulses of the plant. And this sound shows us an abstract level, which gives the plant aswell as the humanbeing an abstract erea with a new substance.
If you "look" at the artwork "PlantMusic" as a measuring technique or as an informatic, it is possible, that you overlook the intention of the artist. It should only been heart,  what you can hear as PlantMusic.
return: Okay, that might be real for you as an artist, but the point that the plant could react sensitiv on a melody or even onpictures, I can see this not yet.
answer: The artist gives with his work only an impuls to look in a new way at plants. He says, you can look at the intelligence and creativity of a plant. And isnt it interesting in this correlation to ask, what the recipient feels when he hears that sort of strange plantmusic or looks at the plantwriting?
Perhaps he becomes activ himself - experience, reflect, bringing out...
