Scott,

I need to comment. I think that orginally the reason arrangers were looked down upon by musicians is because they SOUNDED LIKE TOYS. It wasn't until they improved the sound of them that they became accepted. I played a Yamaha PS6100 for years. I used it as an organ. I never used the arrangments because they sounded fake and toy like.
Remember the early Casios, Bontempies, and Yamahas? They were quite bad. Now even the cheap Casios and Yamahas are pretty good. There are so many musicians out there that don't have a clue how far arrangers have improved.
