Although I loved the sound, I never liked the navigational OS on any of my Korgs from my 1970 ish Korg "PERSONAL" KB, M1/i3/i30/PA 80/60 that I have performed with for live play on stage ......but, being able to edit ALL styles, drum sets, sounds etc....
was a pleasure & one of its strongest features....I look forward to demoing a PA800 asap to see if at all how things have improved ......we all have different needs with gear & I'm always looking to improve mine.
