I am wondering the same. I have an M-audio 88. Not sure if it's an ES or not though. Ok mine is not an ES. It is the full weighted keys. I was wondering about those semi-weighted keyboards and non-weighted keyboards. Are they good? I know most of the metal bands prefers the non-weighted keytars, but Jordan Rudess seems to like full weighted.
Anywho, I want a soft pedal too!.
