You've got one event triggering a Sequence Container over and over again? If you switch to the Interactive Music Hierarchy you could do the following:
Have a state for each note and an event for each of those states:
Note
You make a switch in the Interactive Music Hierarchy with a playlist per state/note.
At the start of the playback of each of your Music Tracks you add a Music Event Cue corresponding to the next note.
In the same Music track, 3 seconds later you trigger another Music Event Cue that triggers the Note1 state.
Lastly you need to stop the switch before playing it again so that the Note1 state is not triggered if you post the event a few times in a row.
Your play switch event would be:
- Stop Switch with a small fade time
- Play switch
Hope this helps, it's an ultimate workaround...
