If you could mention which preset are you exactly using…that would help.
A 4 outputs preset may fall into:
-multi output stereo/mono effect – useful for FoH apps
the first is simply an expanded version of stereo/mono apps, like 2 stereo effects or a mix of stereo and mono ones. You can record it to different stereo tracks or a single stereo one. Keep stereo…stereo!
The second is meant to be used in a quad speakers setup and wouldn't be correct in stereo.
But we don't know…what are you using there….
