I tried this plugin: Poulin LeCab 2.
If I understand it, if you don’t link the two slots, the pan should work normally and can be adjusted independently on the two channels.
Instead, if the two slots are linked, actually, you will only get an increase or reduction of volume, because the signal moves from left to right in one slot and from right to left in the other. If both are centered, they are added together and the volume increases.
In Podium mono/stereo output for a track “depends on the speaker configuration (mono, stereo, or surround setups) of devices in the track effect chain“.
To check (and/or set) the configuration of a device in the track effect chain:
– Project start page -> Devices list (on the right);
– Right click on the device and select Properties;
– In the Device Mapping Properties windows -> Audio configuration
