HI James,

this facility isn't on any other 'arranger keyboard' on the market... not Tyros for example. It maybe on some of the pro instruments, but my OASYS can't do this, so maybe other workstations can, but no other 'arranger keyboard' does.

The OAS system is an advanced arranger with work station elements, but primarily it is an arranger system. And, yes it is the first WERSI product line to offer these features.
