Will sound cards from a mirage sound module sampler(non keyboard type)work on an earlier mirage (grey model Keyboard)i bought this because it had the discs but when I tried to use them in the drive on the kybd no sound , except for the initial start up disc which had two sounds on it .When i inserted and tried to load the other sound discs there was no sound. Do I need the earlier version 2 formatted disc to get the KYbd to play the sound discs?.
