The critical comment is this:

“I’ve noticed the arranger-keyboard fraternity expects Style providers to trawl popular songs for inspiration. That fixation on existing song material is annoying and one of the reasons why such keybord have a bad rap among pro musicians. If arranger-type instruments provided feels and grooves that were fresh and free, their appeal would be broadened. Of course, my opinion is one of personal taste, if you play dinner sets in a hotel lounge, you’ll porbably be extremely happy with what the 9000pro has to offer”

I think the major problem with a number of professional musicians (usually to be found in bedrooms or studios) can be summarised in two words.

Cover Versions.

There has always been an opinion out there that cover versions are un-hip and not worth demeaning yourself with when you could be doing "original stuff" and "not using just the presets".

I consider this to be musical snobbery. Having said that, some pro's who I've met consider that I'm involved in the musical equivalent of prostitution because I happily admit to playing songs I don't like because I know that audience happen to love the tune. I also attepmt to play every tune (whether I like it or not) to the best of my ability. Surely this is a different aspect of "Professional"?

There are a huge number of pro's who find themselves (through choice, circumstance, finance, inability to get on with guitarist / sick of rehearsing with said guitarist to discover he's good at Jimi Hendrix but no use for Frank Sinatra) playing to audiences who require cover versions. Playing original material to such audiences is a fast way to discover the term "paid off".

Arranger keyboards adjust the logistics of entertainment so that a one-person-band can entertain a crowd as well as anyone else.

So what's wrong with that?
