Ian, i can recall..not so many years ago..Uncle Dave and I as well as other players....while playing the same sounds via different key beds ...experienced the vast satisfaction between the sound and the finger connection (and mind)....No one will ever convince me that a better key feel does not make a difference in playability of a sound...

Most if not all..players with a light touch (limited dynamics) keyboard..play wide open all the time...

The semi weighted key beds...point blank offer better dynamics...maybe if you grew up playing accordion..the lightweights feel okay...but you had the bellows to express with accordion...eventually you needed to define the touch for dynamics as you moved on to keyboards...

I have listened to a lot of PSR tunes on SZ, many are good, but dynamics of the sound just aren't there....my guess is because of my above remarks..
