I guess we all have different likes and dislikes. I like the default volumes on the Organ Flutes on the PSR3000. I always thought they were way too loud and harsh on the PSR2100. I know you can adjust them but other sounds always were at a good level, then if I picked one of those, BOOM! I was very happy to find the volumes were set at a lower level on the new 3000.
My only dislike so far on the PSR3000 is the removal of the Harmony button, but I was aware of that before I bought it.
