Using 2 midi keyboard at once

hey guys, i am sorry if this is posted at wrong section, i couldn't find the right place to post it and this was the only reasonable section i could find for this topic.

Ok my question is can i use 2 midi keyboards at once ? i have a Axiom 25 and Oxygen 49. I use Reason 4 for making beats, i use the axiom 25 for drum pads and also the keys for drums they feel much better for drums and i use oxygen 49 for piano and all other purposes. I do have a audio interface ( PreSonus Audiobox ) but i am not plugging the midi's thru, i connected them directly to pc in usb port.

So is it possible to use them at once ? side by side
