What does Forse altro cantera con miglior plectro mean?

According to a footnote in the Tom Lathrop version of Don Quixote, "This is an ill-remember verse from Orlando FuriOSo(XXX, 16). Forsi altri cantera con miglior plettro. After having stated that Don Quixote made a third sally that took him to Zaragoza the rather cocky narrator dares anyone to take his pen and continue the story. The quote means: 'Perhaps another will sing with a better pick.' The pick being analogical with a pen."
