Xiadong Li's comment is well-taken, but, no, the notes in question don't require alternate fingerings to sound properly, volume-matched, and properly in-tune. Although the character of a baroque recorder has a different quality depending on the tessitura, these several bad notes aren't particularly rogue notes. Perhaps the issue is only with the digital signal & post-production intricacies?
I've owned and performed with all the Yamaha instruments used for this library & owned many other instruments from mass-produced to hand-made wonders. Yamaha recorders in this line are very decent instruments, and, imo, well-chosen for this sampling library as they're reliable, have interesting color, and they sound consistent across the ensemble.
