You can take a midi groove from (I have EZ Drummer 2) and drag it to EZ Player Pro with the Addictive Drums 2 wrapper and then drag it to Addictive Drums.
I don't think you can do it in real time though. Again I can build the midi for a complete song with EZD2 and drag it to EZ Player and it will convert the midi to AD2. Then drag that to your AD2 track.
...or you can send me your email and I'll send you an EZD map that you can put into AD2 that will do the same thing most of the time. I had a few instances where the map didn't work perfectly, so I bought EZ Player pro to have when I needed it.
