To be honest my weighted actions were my old spinet , a Wurlitzer , a suitcase Roades, a Yamaha CP-70 & my two ( one for parts) Kurzweil PC2X's . This action on my PC4 plays smooth - - playing rapid repeats is much better than playin' with a PC2X. the action has a nice touch & feel to it a bit lighter. I think that's only because all my PC2X's had - - uh a bouncy resistance while you pressed thru your attack & would slightly bounce before You could respond again. But this just my thoughts . Right now I'm learning the interface & just started making my set-ups (multis). So I'll be woodshedding for a while .
