Did you ever saw a professional musician or a hitmaker or producer that has an arranger keyboard? NO. Workstations have better sounds and sequencer and you can even edit sounds. When I get rid of my arranger kbd I`ll get a musicWorkstation, that has no styles, because I never use them. nobody should use styles, everyone should make their own tracks, like real musicians, real musicians don`t use styles nor arranger keyboards. I think Arranger keyboards just slow down your learning process but MusicWorkstations speed it up.There is only one reason why Arranger Keyboards are better, only when you need to play a song sor someone while they sing. But even in that case Music workstation can do a deacent job.
