Tangent Devices is debuting its new Elements modular control panels for color grading software at the IBC trade show in Amsterdam.  No word yet on pricing or when they will ship, but family of modular panels will be supported by Apple Color, Assimilate Scratch and SGO Mistika, among others.  No word on Black Magic Designs' Davinci, but it would make little sense for BMD to support Avid's MC Color and Tangent's Wave but not the Element.
