"Inspiration for a waveguide model based on Lovecraft's ululating Elder Thing came shortly after the development of Fauna VST. This more complex vocal tract includes a reflective multiport junction. It is a rather eclectic instrument.
The vocal tract includes a monophonic input for processing external sounds. The lightly limited demo is non-expiring. Would that the same could be said for human sanity."
