As I have mentioned before, Casio came out with the PX S1000 and S3000. From what I had read early on, these new keyboards were incorporating both the AIR and AIX chipsets.

The AIR chipset is designed for piano sounds(I gather) and the AIX for acoustic instruments.

The most recent info I have read says that the PX S1000/S3000 contain only the (piano) AIR chipsets.

Anybody know?
