I have the Trinity - and I must say it is hands down the easiest to use, compared to the Yamaha EXxx keyboards.... ABout note droping out, I have not experienced this, altho I am just getting aquainted with my silver beast... Also- Options Options and more add on options... The only thing I currently "dislike", is the fact that Korg decided to call "any" standard single key sample, a "drum sample"...Confused the hell outa me for a bit, and like I said... I still reading....Very good KB IMO..!!
