Yes, definitely worth learning Pierre. My own music reading skill for guitar and mandoline has never been strong enough to read at playing speed but the knowledge is valuable in learning new tunes.

While it's not intended as a reading course, you might find a program such as Melody Assistant useful. You can enter a midi file of your tune in it then play along with it as the music scrolls. It can also produce a TAB so that you can check the fingering.
