Instrument Sound Tuning (Hermode)

Has anyone heard of Hermode Tuning, I mention this, as it will be available as an option (€79) on the Wersi OAS instruments, using the new OAS 7 software, as well as being available with other computer music software. Here is the link to the Hermode site. http://www.hermode.de
I would interested in members comments about it, and whether it really makes that much difference in the real world.
