How to add real drums.

Hi there all fellow experts hope u all enjoying, am new here and by mistake i msg my question in an active thread by some honourable frnds experties, any how hope 2 get some guidence from u, well tell u frndz that i use2 record my guitar in multitrack mood in, Adobe Audition 1.5 and also in Sonar's Producer's choice 6. Now am trying to add reall drum tracks to complete my songz.Am having a M-audio's e-46 usb midi keaboard ,now i wan2 know that is this possible to record reall drumming by a midi keaboard.I think it also raise an issue that even its possible but do Adobe's and Sonar's plateform will allow this , more over an experty told that i can use my midi keaboard to play pro drummings and recording with the help of Synth EZdrummer software.
Is there any site where we can get free and full or at least a fully functioned Fruityloops or Ezdrummers.I appreciate all experties in Advance on reading my topic.
