Without the human aspect, music is nothing more than coordinated noise. I agree with Boo and Wrinkles, someone has to make the music - even music played by DJs and KJs. Someone with individual instruments, guitars, drums, trumpets, saxes, and yes, even arranger keyboards. From what I've been able to garner, much of today's music is written by musicians using arranger keyboards--not synths and PCs. So, at least from my perspective, arranger keyboards will be around longer than most of this forum's members.
Gary, I agree entirely, and when I stop being that part of the music; that human aspect, I will be glad to retire and play for pure pleasure.
In my opinion, a person DJ'ing is not fulfilling the role of a musician...yes, playing a CD player/laptop to an audience definitely requires a certain amount of skill in picking the tunes, talking between songs and keeping the gig moving, but
it is not playing a musical instrument.
Some people like doing this, some do it only because they have to, to compete...some mix it in with a little playing, or Karaoke style SMF singing...thankfully I'm not any of those...not that there's anything wrong with doing those things, but I get a contact high out of playing, and, ever since I started,
it has never, ever, been about the money.
The playing has always come first, although if you do what you love very well, the money usually does come along, and despite some rather hard times, I managed to make a very decent living from playing keyboards.
If I had to resort to DJ'ing of any kind, I'm afraid that would end it for me, because
it is not me being what I worked at since I was a kid...a musician...a keyboard player...
DJ'ing is not playing, it's that simple. There would be no joy for this boy.

More power to those who can do it, and my sympathy to those who are forced to do it to make ends meet.
I'd just rather be playing.
