Hey there. First time on this forum.
So I try to make interesting transitions with the help of transition timeline.
But I’m confronted to some kind of limitations.
First, why can’t I make two sounds fade within a transition timeline?
What I mean is that I can’t superpose two sounds within this transition timeline.
It would be really useful.
Second point, I can hear some soft pops and clipping when going into and out a transition timeline.
Is it a normal behavior?

At last, here is what I would like to do, a living loop with nice transitions :

Also, I tried to put a sound like this :

But this sound in the middle won’t play.

This is a known issue, is it happens. We’re investigating it currently.

This issue has been fixed, and the fix will be included in our next release of FMOD Studio.

Unfortunately, it’s not possible to directly crossfade the source and destination regions of a transition timeline at this time. We will add this feature in an upcoming version, but for now there is no workaround other than “faking it” by placing additional sound modules inside the transition timeline.
We are investigating possible causes of the popping and clipping you describe.
