The user could place a "button" on the sheet.
You configure that button with a "link" to an attached audio file and a timestamp.
When the user taps that button the player will start the audiofile at the specified timestamp.

So you start a playback at "bar 42".

This could be helpful if you have a longer song and want to start somewhere in the middle.

You could already do this. With smart Buttons. Check out smart Button -> load and play Audio track

Thanks, works. Have to invest into that feature ;-)
