Comparable to MuseSounds, less accurate than MS basic
Has many of the same problems as musesounds such as staccatos being much louder or quieter seemingly at random, accents sticking out way too much on some instruments. Different instruments have very different interpretations of the same exact notation (see my review of the free Musesounds Woodwinds)
Slurs everything unless marked with articulations. Slur markings have no effect.
Some blatant wrong notes: Eb clarinet trills are all very wrong. Shocking that these made it past any amount of testing before release, especially for a premium sound pack.
Balance problems throughout, especially with auxiliary instruments.
The demo shows sound flags in use. This is a lie, the instruments do not currently support sound flags.
Many rhythmic problems as well: unevenness, notes cutting out, etc.
One advantage over the free musesounds is that the trills start immediately, making them much more viable for fast music.
While the samples sound nice, MS basic does a better job at representing what’s on the page than both this and the free muse sounds. However, with updates, this has the potential to be very good.
