Hello David,
I don't have the Paramount 341 installed at the moment, so I can't easily check how clearly defined its stereo field is, but I would suggest:
- Via "Organ | Load organ, adjusting rank audio memory options" make sure that the ranks are set to load in stereo (not mono).
- On the "General settings | Audio mixer" screen, for the "Master mix 1 ... main/recording" bus entry in the left-hand list of buses, check that its "Audio output device channel(s): Channel(s)" entry is set to be the desired *stereo* (not mono) pair of channels on your audio interface.
