Casio actually has two sound engines...and AIR and AIX.
The AIR is designed to reproduce piano sounds and the AIX, acoustic instruments.
I just wondered which one, or both, were in the PX S3000.
I would ask this question on the Casio forum but I forgot my password and have been waiting a couple of days for the forum to send me instructions on how to update my password.
