I guess it's the commn opinion that Steinberg's USM is not all that great. It would be nice if the Virtual Sound Canvas was a replacement. Unfortunately it's not. Some sounds are really nice (the acoustic guitar, muted electric guitar, the string ensemble), many are acceptable (pianos, basses), and some are quite awful (violin. the ooh and aah choirs).
For the price it's all right, but it's not great. And what's with the single stereo out? At least the USM had 4!
