I decided to check out some patches provided with K8. Out of 3 Factory Selection brass sounds, all three had huge errors making them unusable. The worst was the solo trumpet, which has multiple double (dissonant) notes on the black keys. Then the G# in the solo trombone (it produces a A) and the trombone ensembles, which have a surprise for you when you play 2 of the F#s. I would perhaps expect this from a tiny Sound Library startup.
