Cubase Sx Delete Right Side Of Stereo Track? Options

[genie27]

Hi,
Does anyone know how to delete the right side of a stereo audio sample in Cubase sx. I was editing the sample with headphone on and only hearing the left channel due to the faulty headphone. When I played it through the speakers i realized that there was an unpleasant sound coming through only on the riht side. I would like to just delete the right side and leave the left.

Any help will be appreciated
