Just a side note...

Just within my friends here are some Pro players that chose and use "arranger" keyboards..

Don Mason
Donny Pesce
Dave Boyd
Jerry Treoce
Harve Mann
Joe Flanagan
Paul Kasper
Kristin Coryell

There are many more.. Sure we use the arranger keyboard in different ways, but we use it as our preference.

There are so many Professional players I know that are clueless about arrangers.


Several of these folks are the best at what they do.
