Fading in sounds

Hey there, I’m using FMOD banks and EventInstances to make sound in my javascript game. But can i do a fade in on a sound? This is because some sounds start a little fast and hard when the game starts up, and it kinda ruins the flow of the game.
I have already tried using .start(FMOD.STUDIO_START_ALLOWFADEIN), but it of course didn’t work

FMOD.STUDIO_START_ALLOWFADEIN isn’t a valid command, all events started will start with any fades implemented.

You will need to add the fades into the event themselves. You can do this by adding an AHDSR modulation to the volume fader on the master track of the event. After applying the fade in, it will automatically play out when you call start() on the event instance.
