Hello.
I tried a MIDI file. ketron Audya and sd5 Ketron. and sounds better in sd5 Ketron. Selection As sd5 has better sound and more body. I have two keyboards. If this year does not improve Ketron sounds Audya sell. Ketron not realize Manufacturers? Sound better sd. Many people viewed the comparison when probe. And they thought the same. Sd sound better. Greetings.
