First of all, I love the marker and tempo system in Fmod Studio – it’s great! One thing I’d really like to be able to do is get access to a list of all the markers in a given EventInstance. I’m working on a music game and I want to be able to mark specific, musically relevant moments in Fmod Studio that my game code can watch for and then react to with cool particle FX, animations, etc.
I was hoping that getSyncPoints() on the Sound class might contain marker data but my testing indicates that this isn’t the case. Is there another place this information is stored that I could get at, or is it simply not accessible? All I really need is a list of markers with their names and timeline positions so that I can use getTimelinePosition() to trigger events in my game when specific markers are reached.
If anyone knows if this is possible and/or how to achieve it I would be very grateful. Thank you for your time!

Currently this is not exposed to the API, but it is a good suggestion. We’ll look at exposing it in a future revision. There would be two ways of getting it, one would be from the event description, and another would be to receive a callback when passing a marker on an instance.
Thanks for the quick reply! I feared as much. I’m trying to setup everything before any markers are hit. But if that’s not possible, maybe I’ll just add extra markers at the start that contain the information I need in their name. This would at least be better than extra metadata files.
An alternative you can use is to enter all known markers into the event’s User Properties section (under the Overview on the far right hand side) and then to use Studio::EventDescription::getUserProperty to pull this information out.
This way you will have the names of the markers without needing to play the event itself and without any extra metadata files.
Cool, that also helps a lot, didn’t know that. Thanks!
Did this ever get added to the API? I actually have a use case where I really do need to know where the markers are in the event ahead of time, before playback begins. Waiting for the callbacks to be fired is going to be far too late.
This has not been implemented yet, but it is in our tracker.
If you really need the exact times of markers you could use the FMOD Studio scripting API to grab the times of all markers in an event.
Take a look into an event’s array of markerTracks for the position of any ManagedObject::NamedMarker
