Hm, you want the trigger or the demo-map? xD
Or should I just explain it? :3
Basically, I run a timer and when the timer hits Event[CurrentNote] (Event is the time at which a note should spawn), it spawns SpawnAmount[CurrentNote] notes at Note1[CurrentNote], Note2[CurrentNote] etc...
Note1, Note2, ... are integers that define the position (there are 5 frets, so the integer can range from 1-5).
If you didn't get all of this, then perhaps it's better to just show you the map
