tip from a 1 year+ castle player
(sorry if the explanation is confusing, english is not my first language.)
if your gonna use a sound that is (for example) 1 minute and 30 seconds long, you would have to trim a 30 second clip from 0:00 to 0:30, and the next 0:30 to 1:00, and then 1:00 to 1:30.
you play the first 30 secs clip, and then add a “wait for 30 sec”, and then add the next 30 secs clip again, then “wait for 30 sec” under, then play the last 30 secs clip, then your done!
