And you can bet that when the demo is being done by one of the manufacturer's pro's - Scott Tibbs or Ed Diaz for Roland; or Bert Smorenberg or Blake Angelos on the Yamaha workstations; or Michel Voncken or Peter Baartmans on the Yamaha arrangers; and the same for Korg and Casio and the others - that the demo board has been gone over with a fine tooth comb by the sound folks and every demo voice and the EQ have been tweaked to the utmost. You could spend untold hours on that same board and probably still not get the sound out of it that they do.
