I have been playing arrangers since day one.....there will never be a perfect one we all know this...just choose what is the closest one that fits YOUR needs, buy it, use it, enjoy it until it doesn't interest you anymore .....then either keep it, sell it, or move on to the next latest & greatest.
NO MATTER HOW YOU LOOK AT IT ....it still is an electronic technology product that will constantly be changing every year that will never end. And believe me its still in its INFANCY we aint seen Nothing Yet...just wait and see! Tyros 3,4,5,6,7,8, Pa800,900,1000,G80,90,101, whats the difference? .......YOur Needs & happiness is the ticket always!
