Reply to CrossFader Curve - Please Help, not sure what I have done wrong.

So I have created my user mapping for my S4 and Traktor Pro 2.03

Everything is working perfectly except for the cross fader curve.

I have mapped the X-Fader to Center.X-Fader with the "Direct" option.

I have mapped the X-Fader Curve to Front Cue Mix with the Shift modifier with Direct option.

The X-Fader Curve seems to be working properly as I have mapped output temporarily to the Level meter D to see if it is adjusting, and the level changes appropriately.

However, this seems to have no impact on the operation of the X-Fader, it only operates in a smooth fashion, regardless of the curve setting.

This also is the case for the Crossfader setting smooth to sharp in the mixer section of the preferences. It has no impact at all, always smooth, regardless of the slider position.

I have looked through all the options, manual etc, I can't find what I have done wrong. Can someone please tell me if I have missed something?

Thanks!
