Does any one think for one second that if you had a hip-hop style comparable to a hip-hop song in 2009 that that style would be able to be use for more than one song?
The reason why arrangers work for the type of music they work for is that most songs in a particular genre work the same.
For example you can play a number of songs on a ballad style (Misty, Teach me tonight).
With Today’s hip-hop, To play an already existing song, you can probably only use one style to do so.
If modern styles were really needed for playing live, you would see a lot of persons playing Motif xs live or Korg M3.
Lets face it, to play an already exiting hip-hop song, people want to hear the original sounds that are in the song. Hence you have a DJ.
And a hiphop song today would be old news tomorrow.
Even Workstations are having a hard time keeping up with modern loops.
