I’m working on a 2D game headed for console and we’re interested in using the surround speakers on occasion. What I want to do with FMOD is move a 2D stereo background loop back and forth from the front L/R to the surround L/R speakers. So I’ve created an event layer with my sound file and added the surround pan effect and some points across time so the sound moves back and forth from front to surround. However I can’t get the sum of the L/R sound file out of the centre channel / speaker. If I try to change the Event property parameter "2D Speaker C" manually to -60db it resets once I audition the event that uses the surround panner effect.

Can I disable the "feature" that sums the L/R into the centre channel speaker?
Why would FMOD do this and not provide designers a centre channel control?

Looking for suggestions – Help !

Try changing the mode in the surround pan tool to 4.1.

Cool thanks for the tip. I see now that each event can have its surround pan set to 5.1 7.1 6.1 4.1. Is this a new feature in version 4.23 ? Can I use this effect in combination with the Event properties speaker output to route multi layer events default to IE: center then use the surround effect on individual event layers to get each layer into different speaker outputs ?

No, it’s been around for a while.

Yes, but the surround pan tool doesn’t handle this very well, so you’ll probably need to edit the effect parameters directly (either use the buttons in the effect control widget, or drag the envelopes).

EDIT >> Sorry I just realized I need to say all these events are setup as 2D !! <<

I am getting unpredictable results when assigning and removing the surround pan effect on layers. After I remove the surround effect from a layer its pan position info doesn’t get reset .. any ideas ?

How does the LFE volume envelope affects the send to the sub ? I want to send an event layer to the Sub but all when I turn up the send level with its layer envelope it doesn’t seem to send. When using the "Add change points at cursor" button in the surround pan tool I get a value thats literally off the envelope scale.

What is the relationship between Event property speaker output levels and the surround effect ? Why do the Event property speaker output levels change after auditioning ?

If you have the Surround Pan dialog open when you delete the effect, it overwrites the event’s speaker levels with the effect’s values. As I said, the Surround Pan dialog doesn’t handle this situation very well. We are planning to fix this. For now, don’t have the Surround Pan dialog open when you delete the effect.

Thanks, we’ll look into it.

Are you leaving the Surround Pan dialog open in the Event editor tab? If so, it will overwrite the event’s speaker levels every time you switch to that tab. We are planning to fix this issue. For now, close the Surround Pan dialog when you’re not using it.

Thanks your feedback is very helpful.

I’ll try moving to Designer v4.23.05 and use the speaker level effect on these layers instead.
