hi, i made an event that contains the doppler effect, when playing the effect it works fine, but when i want to add the event to the sequencer it works fine but the doppler effect doesn’t work, does anyone know any way to make it work in the ue4 sequencer ? Thank you.

Doppler is working for me in the sequencer without any additional setup. What version of FMOD are you using? Perhaps try turning the Doppler Scale up to 500% in FMOD Studio to make sure the effect is as obvious as possible?  
EDIT: Also, what version of UE4 are you using?
