Most of the PianoSoft products would "last" longer to me if the accomp parts were believable. There is a lack of grit when needed. Vibratos are too too... They are nice for parties, when I don't listen as closely.
On another note, I have a good friend that has been producing transcripts of choice Bill Evans Albums. He then takes the transcription and produces the performance on a DisKlavier. It's amazingly accurate. Not sure what he plans on doing with the files as he has concerns regarding the copyrights, etc.
