The recorded samples are full and bright, and help the instruments' characteristics shine. Note: most of the pianos appear to have upper limits to F7, rather than C8. Also, they seem to be balanced similarly to their real-life counterpart (as such, they're a bit quiet).
Buyers beware: the harpsichords have no option of changing or coupling registers. Regardless, the sound quality is good and it's more than worth it for the pianos.
All harpsichords are great, the Austrian Harpsichord has a limited range but it's nice overall. All the pianos also sound nice and have a very nice timbre.
