Panner sound front to back

I need to make an automation panning for a sound in a 4.0 out. The sound just has to go from front to back. It was easy in FMOD Designer, because we can control front/back parameter but now in FMOD studio i can’t make an automation for the axis from 0 deg to 180 deg while staying in the center (and not use a path by the right only or the left only…). To be more explicit i made a video of what i want to do.

You should be able to do this using automation. I tested with this and it works fine:

You can open up the parameter sheet controlling these and zoom in to make more precise curves than in the deck widget.

Hello Richard,
Thanks (again) for your help, i will try to do this !
Have a nice day,
