It's fairly easy for me to work with ( 2k in my case ) . Just a matter of getting used to it's OS after 2 plus years with the PA80. It would be a winner for me for live play ( 2k or 2100 ) if... there was a seperate real time control for panel voice volume ala the PA80's assignable slider ( I like adjusting on the fly ), and the key feel was better. Still, my 2k has some practical uses here in the studio and I can live with it temporarily for live use ( for as little live work as I do ) IF the PA80 ever went bad on me. I always feel more comfortable with a backup even though my PA80 has never had any glitches / issues from day one. I STILL love the thing after 2 and a half years. That's gotta be a record for me ( although I loved my poly6 for many years too )
