I am using Sonar X3 and have a Session Drummer beat that I am working on.  I'm not sure what happened but now when I press the playback button - no matter where I am in the timeline - a four count, random drum beat plays once and then stops.  It's not a beat that I programmed in but sounds like a pattern that was pre-written.  It's possible that, in my editing, I accidentally dragged the midi file in from somewhere (though from where I can't imagine).  I've cleared all step sequences in my Session Drummer folder.  I know that it's happening from there because when I solo the folder it plays but when I mute it, it does not.  This has rendered all the work I have done useless because now there is a 4 count drumbeat that I can't get rid of.  Does anybody know what is going on?  Thank you.

I can tell by your other post you are not familiar with the Piano roll view.
If you convert the SS clip to Midi data the PRV will solve all your problems.
Its a road map of every single drum at every single point in the project.
 
Right click on the midi clip and choose Piano Roll View.
then look for the notes/midi data where you are hearing this 4 count.
Should be pretty easy to see as they will be the only 4 notes on that part of the grid.
