So I got myself an Akai LPK25 and a Korg Nanopad and am running reason 4

My intention is to run my keyboard through an NN-XT for piano sounds
and use my Nanopad with reDrum for drum beats

My Issue is that I can't do this.
I've set it so the LPK is on bus A and channel 1 is the NN-XT
And Bus B is the Nanopad and channel 1 is the reDrum

yet the issue is I can't get my nanopad to make any noise. When I hit it the redrum buttons light up showing it is recieveing but no sounds. Also when I hit the LPK25 the NN-XT works but it also is showing to be tirggering the redrum rack too though no sound is coming from it

totally at a loss here
