Watched folders
Current folders
To play songs in Synthesia, it must locate the file. You use the 'Watched Folders' for this.
If you have found a new MIDI's you should be able to just drop them in the "Synthesia Music" folder in your Documents folder. The next time you start Synthesia after that, they should appear in the song library.
On the Select a song screen click Managed Watched Folders
Adding a new watched folder
Click Add New Watched Folder then select where you have place your midi's
i.e C:\Users\stephen\My Documents\fat32\music\midi. If you have folders inside that folder select 'watch its sub-folders' as well so it will watch the whole midi content of that folder.
