Korg wins in sound editing dept.(also in sequencer dept too).

They have bull blown worstaion sound board with same editing power in ALL arrangers and they have ben consistant.i3 from x 3 to triton to Pa series(munus EFX number in Pa series,but has the same # in previous I series comparing to the workstation of thier time).Not GM/Gs borad and MU boards like previous Rolands or Yams.New Roland and Yams are changing but not yet totally.

The only difference is combi mode,but program and seq modes have the exact same power like a workstation.

But OS,fills ...Hmm that's different story.
