ENRIQUE,

The AJAMSONIC retrofit kit doesn't add new sounds to the SX-3000 pr SD5. It adds new sounds to these units utilizing their built-in SAMPLERS:-
* KETRON X1/X4/X8
* KETRON SD1/SD1 Plus

It adds over 2000 new Mp3 songs to:-
* KETRON Midijay and Midijay Plus

It replaces old Floppy Drive with USB Drive so you can easily transfer data between your computer and your
* Ketron MS-series, X-series, XD-series, SD-series SD1-series and Midijay series.

It adds more RAM so you can load more styles into your machine.

It adds over 100 new style (depending on which machine you have).

It provides new Sound settings so your current factory sounds are even better.

It adds new Vocalizer settings so you experience better harmonies and less/no feedback!

Thanks,
