Hey, I have a Privia PX-320 with a "60's E. Piano" setting. Which electric piano is this modeled after? I love the responsive, harsh tone I get when I increase the velocity and hit the keys harder. Can anyone explain why this particular electric piano does this? The other electric pianos on this Privia don't have a harsh responsive tone. They just get louder.
So, I wanna know
1. What instrument is the "60's E. Piano" modeled after
2. What is it about the 60's electric pianos that creates a harsh responsive tone with increased velocity?
