Time to score!
What I had to do was I had to export each instrument (each part) as a midi.
I then opened it up in Sibelius, created a new score, added the instruments I needed and copy and pasted each part in.
Now, the notation was sometimes absolutely ridiculous, with demi semi quavers out of nowhere instead of a quaver. I had to go to > Note Input and click >Renotate.
However, sometimes even renotate couldn’t fix it so I would fix it up myself. Luckily because of the repetitive structure, I could copy and paste the fixed rhythms and fix up the rest of the score.
