Hi,
I attach a ZIPped Reason Song with EZdrummer 2 Multi Out assigned.
You can assign the mixer faders in the EZdrummer 2 mixer to which one of the 16 Stereo Outputs you like.
The PlugIn Outputs are all Stereo, so a Mono mic would be panned Center, if you are not splitting a Stereo Output into 2 mono mixer faders in the Reason mixer, then of course you pan L or R in the EZdrummer 2 mixer.
