To the Genesys puts:
if you want to sound like a DJ or a Karaoke machine, then get a Casio or PSR/Tyros 2.
But if you are gigging and want to stay in the music business and want to have an identity as a performer, then you should be prepared to work, tweak and create.

I think you'll get some strong comments back from that statement.
Loads of us on here regardless what type of arrangers we have always tweak our instruments and create our own styles and sounds instead of using the presets. As for sounding like a DJ or Karaoke machine, that comment is pure c**p, unless you just shove a disk in and let it play itself.
Many on SZ have also been in the business for years and even have their own music shops or teach music etc so we already have established identities and certainly put the man hours in when it comes to work.
By the way, what keyboard(s) do you have. With Genesys I'm assuming it's the one by Gem?
