Korg's TOTL cycle was every four years. i30 in 1999, Pa1x in 2003, Pa2x in 2007, Pa3x in 2011, Pa4x in 2015. So here we are five years on, but still no new board from them. Either they've been hindered by the pandemic, or have tended to focus on lower models, EK-50, new i3 etc., or they've got something a bit special up their sleeve. As always, only time will tell.
