Midi Vol. CC behavior from external controllers

[luiggy santiago]

I assigned midi cc to change volumes in differents channels on my Receptor . I did in the Midi Mixer area using the midi learn option .
When change the patchs every vol. return to the saved value . Thats very nice . But if i move from my Korg NanoKontrol2 or Novation SLMKII a fader to bring down the volume in some channel the Receptor's fader slope down very quickly.
I like that the Receptor not move vol. until the ext fader reach or touch the saved value.
Any comments on this?
