https://musescore.com/musically-artistic/scores/3569171 https://musescore.com/jestermusician/undertale_megalovania Thanks! I used your scores to name all the notes and rhythms :) (I can't read F clef so it is more a pain to read, had to improvises and switch up rhythms, so not exactly the same rhythms as the original) It is crucial to press the flag as much and as quickly as you can to make sure the two parts sync together as close as possible. Otherwise, the parts will be a beat off and everything won't be correct. Click it enough so the first few notes sound synced :P If it still doesn't work, you can go inside and disconnect one the parts so Scratch won't ever read it and you can just listen to that part. Sorry! Another way to re-sync it is to "see inside" and click between costumes and scripts to get Scratch to lag, and "refresh" so it syncs better. Try to do this when the piece is in the middle of a lot of notes. The faster the speed, the less it is synced. If you are eager on hearing this faster, you will here it less synced. I have decided 145 (the speed I set) is the fastest and the most synced I can make it. Often it falls behind on the line with many notes, and that drags it behind by just a bit.
