MuseScore Sheets
The audio for my original compositions is at https://andyalt5995.bandcamp.com/
You can view and play these scores at https://musescore.com/user/151255/sheetmusic but the audio may not be as good (some of the instruments are too loud).
Some of the PDFs for this sheet music can be downloaded from https://andy5995.github.io or https://commons.wikimedia.org/wiki/User:GravityIsForSuckers/Sheet_Music_by_Andy_Alt
