[Edit]
Never mind! The issue was caused by an amp effect placed after the master track.
On the V4 machine that I’m using, the audio output is mixed as one single mono channel, therefore I am unable to pan each track across the stereo field. I have tried different configurations and cables, but so far nothing works.
I wonder if there is some admin setting that is causing this strange behaviour.
The machine is running the latest ORAM version.
Thanks!
