Playing arranger kb is a multitasking art form that not many have the talent to pull off. And to add singing to the mix makes it all the more enjoyable and efficient. They tend to think it's too difficult
and in turn go to the easier way of just playing a single type kb, piano, synth, etc,.
That is fine with me, I'm happy and proud to be able to play one to the best of my ability and learning more every day. ....
As far as killing it off that is not gonna happen IMO.
