Mixer Tracks Not Opening For Battery 3 Multiple Outputs

Hi!

Could somebody please tell me how to set up my mixer in Cubase LE5, so that when I open Battery 3, I can put different sounds on different channels. The only sounds I hear coming from Battery 3 are the ones assigned to the master output. My older version of Cubase automatically opened up separate mixer tracks for Battery 3.

Thanks in advance.

Neil.
