No one really cares about the greatest sax sound or a bunch of horn lines in the background. If you've got a simple solid rhythm backing, some chords to fill in and a decent voice your good to go.
That about says it all for a working OMB KB pro today....
add a versatile Powerful PA for
all types of gigs & a laptop your good to go..
as a side note:..........
Yamaha & others should start thinking about years to come when all the 60's, 70's, 80's, "Wooden ORGAN BABY BOOMERS" are all gone,.....players will have many different needs when it comes to automatic arranger Kb's or whatever comes next down the pike,......
