one advantage with an arranger, folks with little or no keyboard experience can be playing songs in a short while.
Not sure that's an advantage WHEN MARKETING TO MUSICIANS; the general public, maybe, but not musicians. Despite arguments to the contrary, sales figures don't lie.

Most pro musicians don't even know what an arranger kb is ......
just ask a few of them......they are just thinking toy casio kb sold in big box stores for $199.00 for kids....digital pianos and synths rule the roost on a pro stage just look around thats the way it is..
its the "Automaticness" and "Repetition" of an arranger kb that turns them off ......real musicians want to create music not operate an auto accompaniment machine....sad but true.
