Korg Pa4X-61 specs
Korg's flagship arranger from the second half of 2015: the Pa4X 61 with EDS-X (Enhanced Definition Synthesis-eXpanded), more than 1,900 factory sounds, more than 580 factory styles, aftertouch on semi-weighted keys and 13.9 kg - with no built-in speakers, the PaAS column being an optional extra. It has since moved into Korg's Product Archives in the UK and DE catalogs, with the Pa4X ORIENTAL variant archived alongside it; Korg never published a discontinuation date.
