I believe you have nailed it right there, John... Different people like different arrangers because all of them do something well, something not so well, and what YOU personally need is usually very different to what THEY need!

I know my needs in an arranger are the basic rhythm section (bass, drums and guitar) to be as live as possible. The rest, I really want to play myself if I possible can! And, of all the rhythm section, the drums are the most important. That's why I go for the Roland stuff, who have had this nailed for a long time, and only keep getting better! I admit, Yamaha's guitars are a bit better, but the drop off in the drums is too radical for me to abide. I envy those Mega guitar sounds and patterns, but I CAN live without them... Can't live with those wimpy drums, though!

Arranger players are SUCH a wide demographic, from One Finger chord players pecking out a one finger melody, to pros who want as little machine as they can get away with. To me, at least, there's no surprise that each of us is so attached to one manufacturer or another, as each of them tends to address the needs and approach of only one kind of player BEST... Sure, they'll all do in a pinch, but usually, one is better than another when you KNOW what you are looking for!

On the whole, being very familiar with my G70, I have little problem editing the BK's. It simply takes longer, because of the loss of the touch screen. But all the functions are there (with the noted loss of the Mark/Jump and Dynamic Arranger), it just takes more navigation to get there. But compared to most non-touch screen arrangers, it's about the same. John's headaches aren't a result solely of the Roland, he gets them anyway... At least, he gets them editing ANYTHING for any length of time..!
