Hi there! I just got a pair of second hand D2 controllers, but they come with DJTT Chroma Caps, which are not touch sensitive, so I can't access to all the functionalities of the devices. I've been looking on google for some replacements, but it looks like there are not third party suppliers of them. Has NI any stock of them? and would it be possible to get 13 knobs and 4 encoders all touch sensitive? Thank you!
