Hence my mixed feelings. I absolutely want to hear exactly what I am recording, but in FX work I will also use different mics and things that will bring out the qualities I or the editor is looking for. So a variety of filters might get used, but one fixed one, especially the curve that you show is not something I would use often, and like a low roll off I want to be able to not use it.

While I have never been a fan of the SD recorders menue's or small size they have been a very supportive and solid company and I like their quality a lot. Since the curve would drive a lot of FX recorders nuts and that hs been one of their early adopter markets I suspect they will have a firmware fix.
