In a music event, I have an event instrument that I just want to keep playing while a transition timeline happens and after it is done, but currently I am not able to do that. Can anyone help?
What currently happens
Music plays in the “Left Gallery Circumference” loop where the event instrument is started
The progress parameter makes the playhead enter the transition timeline. The event instrument keeps playing here, which is what I want
The transition timeline ends and the playhead enters the “Progression 2” loop. But now FMOD starts an additional instance of the event instrument so I have 2 playing on top of each other, which I do not want
What I want to happen
3. The transition timeline ends and playhead enters the “Progression 2” loop. Here I simply just want the event instrument to keep playing
As of the time of writing (July of 2025), there is no way to prevent a transition timeline that includes source and destination regions from retriggering instruments on the main timeline that cover both the transition’s source and destination points. This is because the presence of source and destination regions means that the playback position is being removed from one part of the transition timeline and placed on another one, re-entering any instruments at that point and thus retriggering them.
As such, if you do not want an instrument to be retriggered by a transition timeline, your only options are:
A. Place that instrument on a parameter other than the timeline, or on the timeline of a different event.
B. Avoid using transition timelines.
C. Position the instrument such that the transition timeline does not retrigger it.
You’re not the first person to want to be able to use a transition timeline without retriggering an instrument on the main timeline. I’ll add you to the list of people interested in this featuree.
