Mixxx 2.3 Can you use Muliple MIDI controllers together?

I use an old DJ2GO with Mixxx 2.3 beta on Ubuntu. It works perfectly.

Is it possible to use a second MIDI DJ controller at the same time as the DJ2GO? I wish build a custom MIDI controller using an Arduino to and map it to play samples without resorting to using the mouse or keyboard.

Thanks in advance.
