Rekordbox DJ with two Behringer CMD-PL1

Hi Guys,

I need some help with my current setup. It consists of:

- MacBook Pro 13" running Version 10.12.6

- Recordbox DJ Version 5.0.3.

- 2 Behringer CMD-PL1

When connecting the 2 controllers the MacBook recognizes them as two different devices, however within the Recordbox Midi-Setup it only recognizes one of them. I think the reason is that they both carry the same device name.

To go a little bit more into detail:

When I connect the 2 controllers, Recordbox detects the one whichever I plugged in first. I then can create a MIDI-Mapping without any problems. As I can't address the second controller I've also already tried to only plug in one controller at a time. The problem then is, that Recordbox automatically loads the MIDI Mapping of controller 1, also for the second one. This is not working for me as the mapping is created for Deck A and I intend to use the second controller for Deck B.

Any Ideas on how I can fix this? Many thanks in advance.
