Is it possible that this feature is broken?
It plays differently than it should every time.
If I set the sound source for each track hard, then everything plays from the correct speaker. The back plays from behind. center from center, etc.
If I want the sound to flow smoothly from one speaker to the others, mega hell ensues.
This doesn't work:
If I don't turn on automation, I can't determine the route manually.
If I turn on the automation, the tracing works, but the audio plays poorly.
For example, it starts correctly in the rear speakers, but as it moves to the center speaker, the front speakers play as well. When the cursor moves back again, all speakers play.
When scrolling it plays fine for a while, but when you move the cursor it gets angry again. The sound does not respect the path and position of the cursor. For example, if the cursor is on the left front speaker, the others play a bit too, and other times it's different. As if the whole Surround panner was misaligned.
Otherwise, it works if I scroll manually with the cursor while running, and otherwise with automation.
I can't explain it more. Not everyone has a 5.1 speaker.
