Reply to Production set up

Right a few questions, I curretly have a Xone 4D which allows me to run my 1210's and traktor and i have my powered monitors via it, and a i run ableton on my laptop using a novation compact 49 sl for keyboard, going to sell my Xone 1D to cover anything else I fancy and currently that's an APC 40 by the looks of it, really want something purely for controlling Ableton as the mixing side if covered perfectly with the Xone 4D

so would you reckon the APC 40 would be a good addition if i am only going to be using it solely for production rather than anything else?
