Other programs from Filter Forge Inc. ?

I wonder if Filter Forge Inc. is thinking to make also other programs.
I think that the basic idea of FF is very good and could be applied also for different programs.

For example, a synthesizer.
Most synthesizers are not very intuitive for people who are not professional musicians. Using the idea of the components of FF and having every component representing a different sound effect, then connecting them with a band representing the total time of a song, it would be possible to modify or create a new song very easily.
I think it could also sell well, especially now that programs like Vocaloid are having so much success.
