Custom cues in a music segment should have the ability to post an event directly. This functionality would be very powerful so that events could be called at specific points in the music, and drive actions within the sound system.
Example uses:
1. An overlay stinger could set states when it plays in order to do volume rides or apply filters to other music and sounds, with precise control over the in and out timing that is content driven.
2. Cues could set switches allowing pitched sfx to follow chord changes within the music.
Even if this involved some basic scripting, that would be fine. e.g. Cue name: PostEvent(Snapshot_01)
