I think it is what OS[manufacturer ] you are use to...
I have no problem understanding the G70, but I am use to Roland arrangers..
I find Korg and Yamaha less friendly and less efficient to me...why?... because I am not a Korg or Yamaha user..I've owned them, I just don't care for the OS..they use..
Likewise with Ketron..I didn't like the OS with X1..and it is the same today..
Roland has more versatility and maybe that is why some folks feel it is very steep learning curve..I can understand someone new to Roland getting frustrated..Patience is a virtue..
