Hello,

@AJ

Thank You for this explanation. Now i know that the upgrade is only possible by a Ketron service center.

@Leezone

The by AJ mentioned procedure is only for soundboards with missing memorysockets.(First generation boards)
If your keyboard has SPDIF-connectors on the rear, then it is a first generation soundboard with missing memorysockets.
When there are no SPDIF connectors, then the memorysockets are present, and the upgrade can be done by simply insert the Ramexpansion on place.

Best regards,

Carlo
