Modify CTC AKAI LPD8 Remix Deck Control C & D

Hi

I have set up Traktor with my Numark Mixtrack Pro II and the CTC AKAI LPD8 Remix Deck Control C & D mapping.

What I am now trying to do is modify the CTC AKAI LPD8 Remix Deck Control C & D mapping.

I will only ever use only 4 decks /effects and want to remap 3 of the pads in the CTC AKAI LPD8 Remix Deck Control C & D mapping to have the ability to Top Kill Mid Kill low Kill which is not mapped on the Mixtrack Pro II.

Could someone help as to how I would go about doing this?

Regards

Desmond
