Most pros don't work as OMB's, I guess...

They play in bands, or do studio work. Neither need the Auto accompaniment of the type that is current in arrangers, and what accompaniment they DO use is more loop and arpeggiator based, which is a LOT more current in flava...

For whatever marketing reason they have managed to self-manufacture, all of the arranger manufacturers have drawn a line in the sand, and adamantly REFUSED to voice an arranger as contemporarily as their WS line. This is slowly sounding the death knell for the arranger divisions, as few younger players or professionals with contemporary tastes are able to use them, despite their many advantages in live operation from WS's.

Sad, really...
