Check your settings as Kent pointed out.

Increase the buffers a few steps at a time. Reduce the latency as well.

You didn't mention what soundcard/interface you are using or the driver mode it is running.

I've had issues in my laptop mainly, when I run Sonar with BB & RB all at the same time. Sonar grabs ASIO and then BB & RB have to use MME. Of course, MME isn't good with midi & audio in the same project so I get all sorts of wonky things happening.

Add nothing that adds nothing to the music.
You can make excuses or you can make progress but not both.

The magic you are looking for is in the work you are avoiding.
