A hopefully simple question:

I had one mf3d, loved it, so I got another. Traktor only recognizes one each time I start it until I go to my copy of the mapping I use and set its in and out device to the mf3d listed second in the list. Looks to me like it's trying to set both copies of the mapping to the first mf3d it sees.

How can I fix this so it recognizes both mf3ds on startup?

Thanks!
