First World Minstrel: Echoes of the First World

Relevant rules text:

<snip>
Bardic Performance: A First World minstrel gains the following types of bardic performance.

Echoes of the First World (Su): A First World minstrel infuses himself or a single willing ally within 30 feet with the strange magic of the First World, granting the target one of the special abilities from the fey creature template (see Pathfinder RPG Bestiary 3 116) other than change shape for 1 round. For every 3 levels beyond 1st the First World minstrel has, he can target one additional ally or add an additional special ability to one of his targets. This is a polymorph effect that relies on audible components.

A few of us are unsure as to how this ability exactly works and feel the wording is unclear. Particularly the "for one round" portion. Basically, can this performance be maintained for a benefit, or does the 1 round limit shut it down and require you to start a new performance to gain the benefits again?

Seems pretty clear to me. For one round means it can't be maintained (or rather that maintaining it doesn't do anything.) You would have to spend an action each round if you wanted it to continue.

I would say that is is plausible that this was a mistake by the writer and wasn't intentional, but how it is written is actually clear.
