ez drummer- how to ?

you need to map out the song in sonar,meaning put in the track what you want to hear.
if you want to hear this sample over and over again,well you need to drop it in over and over again/or turn it in to a groove clip and drag it to lenth(as long as you want it)
see you could hit the loop button in ez drummer but all that's going to do is loop the example your hearing,not what you want to record.

in your case its not about recording,its about mapping,mapping a drum track in the track(not to be confused with drum mapping.)track mapping is totally different,its basically creating a song out of your drums.
