Issue: Stereo Track stuck in “Combined Panner” mode
Discussed with confirmation here.
The stereo panner options disappear when routing a stereo track to a 5.1 group and then reset the routing back to a stereo group. It should be possible to select “Balance Panner” and “Combined Panner” again as usual, but the options disappear and the track remains in “Combined Panner” mode.
Normal stereo track (routed to a stereo group):
Stereo track that was routed to a 5.1 group and is now routed to a stereo group again:
Edit: It came to my mind that this bug might be releated to this one here: Render in Place adds more channels to an audio file than expected
Something seems to be wrong when routing a stereo track to a 5.1 track (or any other multichannel configuration) and back to a stereo track. As if the stereo panner internally stays a surround panner then.
