Random drum beat is playing at playback
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.
