It is possible to add Polyphony via software but it all depends on the architecture of the instrument. I don't believe the PA2X can add polyphony via software though as its an embedded product, but it may be possible. Who knows, maybe Korg has a PC hidden under the PA2X shell?
The Korg Oasys and Wersi Abacus both added polyphony in new software updates. These of course are computer based instruments so they have an advantage over embedded instruments in that they aren't fixed. Just another one of the advantages an Open Architecture keyboard has.
By the way... the PA2X Pro does not use the same sound chip as the Oasys. It may share some of the same type of sounds but not the same sound chip. The Oasys uses the HD-1 sound engine, the PA2X Pro the EDS sound engine. While quite good sounding the EDS engine does not have the dynamic range or filtering that the HD-1 engine has.
