Step Sequencer confusion

greetings, I'm pretty new to this, so I apologize if this is a stupid question, but I pawed through sonar power (book), various tutorials, etc, and struck out. I set up session drummer so each instrument goes to a track, and all seems great. When I open step sequencer (clicking on the button at the top left of session drummer) the instruments in the sequencer don't match the drum tracks that have been created when I inserted session drummer. Several sequencer rows are listed as things like handclaps and sidesticks, both of which just trigger a snare shot. Any suggestions what I did wrong? Can you edit the row instrument assignments in the sequencer? Thanks a lot! This forum has been a life saver. w

Thanks Barczar.
