With the KORG pa3x you can make it as EASY or as deeply intuitive as you want digging into the awesome Os functions to create music.
Yea the G70 is a nice arranger KB even with the weight issues...but lets face it its getting a bit old in it's technology. NOT a bad thing just a bit dated....to some its fine ...but to others who want to stay with today's technology it pales in comparison. I personally have NO PROBLEMS performing every night on stage with my KORG PA3x it does so many things to serves MY needs in a spectacular fashion. The easy to use on board deck layout and navigation is amazing for the live KB performer....and YES I have played & performed with my G70,Tyros,Sd1,S910..etc,etc,etc,.. and so many more KB's...We can talk all we want on here till we're blue in the face, but baby I gotta "HEAR IT" to believe it, until then it's just endless "mine is better then yours" over and over again, which gets old fast. Less talk more playing I say!
That said I love my KORG PA3x !!
