Ignorant people have been thinking like this for years about the arrangers of today; some even still call them organs huh. It's not the instrument that makes the musician, it's how he/she uses it. The time they put into it and the passion from their hearts to allow the music to come out to be enjoyed by any who want to hear it.
Arranger players can be just as talented as any concert musicians in technical ability and agility. It is on arrogant people tend to "overlook" the skill and talent of the player.

The new professional arrangers have sampled sounds from the real instruments as well as natural accents added to enhance the sounds and effects or the nuances of the acoustic sounds. These "extras" make it possible not to sound like other players. Being able to play over MP3 files etc have changed the keyboard player repertoire from the old fuddy duddy style to something real and individual.

Start listening to some real players they are every where, look in night clubs, hotels, pubs, clubs etc, as the arrangers are being used in modern music to back up the singers. Who will pay for a 5 piece band any more, but you have them in an arranger player - he/she is worth 5 players pay any day!!!
