Hi! I have a laser pulse drill sound that I have in a Multi instrument, it contains the start up sound and then it loops the sustained sound until release of the mouse button which then triggers another event with the cooldown multi instrument. My question is asking if i can achieve this in one event? Is there an easy way to end the loop and trigger the cooldown sounds ? ---

Yes it is. I would go with a sustain point! ---

Any chance you can explain a little further? ---

Yes I can. How is set the main loop? Could you share a screenshot? ---

What I have in mind is something like this: ![image](https://canada1.discourse-cdn.com/flex036/uploads/fmod/original/2X/c/cd1af3f1f21ff40da665a9b2750c57e73cf932e8.png) When you trigger “Key Off”, it goes seamlessly to the cooldown. But this assumes the multi playlist entries blend correctly together by themselves. If that’s not the case, you’ll have to setup a nested event. ---

Was easier to just trigger a new event for the cooldown but i want to learn how to do this on one event ---

Love this solution. How did you get key off to trigger the ending sounds though? ---

Ok, so with what you have, the solution will be something like: ![image](https://canada1.discourse-cdn.com/flex036/uploads/fmod/original/2X/0/0d4b1e3a3f5ee96b16906d8c7145751809bc4c75.png) The nested event will be your actual event (without the cooldown). > [@DavidDagostino](#): > > How did you get key off to trigger the ending sounds though? If you mean in Unity, I don’t know! Check the doc! ---

Just meant in FMOD more. So basically its the same result as just having 2 seperate events that are triggered in Unity. ---

Just press here: ![image](https://canada1.discourse-cdn.com/flex036/uploads/fmod/original/2X/6/62b7082133c92cf5765d94a26b411afebda0024d.png) > [@DavidDagostino](#): > > So basically its the same result as just having 2 seperate events that are triggered in Unity. It’s better, because it’s nested in one event, so it’s handled by fmod. It’s fmod’s job! it really shines with complex multi-levels nested events. ---

The button will appear when you put a sustain point in the event. ---

Your setup is not correct, the playback is stuck in the loop and never reach the sustain point. Why don’t you try the way I showed you? ---

The nested event doesnt play anything when i press play. ---

Just to be clear: your parent event must be a new empty event, in which you drag/drop your actual event in it (it will be the “nested event” I’m talking about). Did you do this correctly? ---
