Reply to VCI100 crossfader curve/volume help needed!

I have been a little annoyed with the crossfader curve on the VCI and traktor mappings.

At the minute its like "B" here

Which cause the volumes of the town tracks to "mount" on top of another during the mix, resulting in peaked volume.

I've looked everywhere and come up with no solutions. i'd like a dipped or intermediate curve like shown below that i had on my old hardware mixer.

is there anyway to do it?
I'm crap at midi interfacing otherwise i would have a fiddle myself.

There must be a way to adjust the settings.

Any help appreciated.

thanks
