A full day working on the sheet music for The Flatspace Soundtrack. There are many annoying aspects of MuseScore 4. The way the notes used to light up when a tune was played was so helpful, and is a massively requested feature by users, so much so that all requests for it are deleted as 'noise'! Yet, after years of requests, it remains ignored. The workspace/layout option is so bugged it won't work to any degree. Yet, MS4 it is faster to use than MuseScore 3 due to small improvements.
I've managed to complete all of the scores in draft today, an exhausting 12-hour day of work on them. The score for The Spiral Staircase Pt. 4 is 20 pages long, even when the blank staves aren't there, but none of the music is complex; it's all extremely simple and repetitive. This is perhaps one difference between that ancient music and my newer music.
I did some programming too. There's a feature to expand an arpeggio in Prometheus into individual notes. I improved that by making it expand only the next instrument in the sequence (if requested) rather than all, so that (for example) a major arpeggio can be expanded, then later the minor one. This speeds up transcription.
