Certainly there's nothing wrong with the sound quality of the audio drum based styles...they sound very good indeed.
The issue Mirza and myself have with them is the way they have been implemented, and I also personally feel the styles themselves should have been made more editable and offer more storage options.
These issues also apply to the S950, which has similar audio based drum styles.
Again, this is not a criticism on how the styles sound...just their execution.
More kits would have been nice and probably a better idea.
