Stop EventInstance without click-noise?

Is there a way to stop an event without a clicking sound?

I tried eventInstance.stop(FMOD.Studio.STOP_MODE.ALLOWFADEOUT) -but i dont know where to set a fadeout.

Is there a way to stop events not so abrubtly?

You can set a fadeout by adding an AHDSR modulator to the event’s master track volume. Just select the event, right-click on the volume knob on the Master track, and select “Add Modulation->AHDSR”. Then you can tweak the Attack and Release values on the modulator to control the fadein/fadeout.
