Set midi controller to load next track

Hi DJ hive-mind,

First off, sorry if this has been covered already, I didn't see a post related to this though.

I have a question regarding midi mapping, I use a pair of technics 1200s, a DJM 450 and an akai lpd8 for cue points along with my laptop and rekordbox.

I was wondering if there was a way to use the midi mapping function to assign a pad (well 2 technically) on the lpd8 to load the next track on a playlist to either deck 1 or deck 2.

The goal is to be able to put my laptop to the side and focus on mixing, I find having the screen in front of my face draws my attention.

I had a look but I couldn't spot a midi function that looked right.

Thanks

Chris
