Sorry Korg, I'm an Old Man at 67 and my PA4x is now equipped to run rings around the new 5x. You waited too long. VS making the LARGE Investment from the 4x to the 5x I chose a different avenue, a Kurzweil K2700 as a 2nd Master MIDI and program any knob, switch or slider to drive my 4x, DAW or any combination of audio interfaces (the UAD, K2700, Focusrites & Mackie all running happily on an M1 MacBook Pro Max w/32 gb memory and 4 TB of Thunderbolt 4 SSD with everything under control when need be of an iConnect MIDI System. My training is Old School, classical & theater Organ so there's also a 17 pedal StudioLogic "Real" MIDI Pedal Board plus Korg's very own ECM5. If this rig won't pull it off, I either don't need to be doing it or it serves me no purpose. IMHO, the OASYS Should have been left on the back burner as the OS would have been compatible with today's ARM Architecture requiring only small unix/Linux tweaks to get things in line. I would not have had to go into production. Merely sit on the shelf until the silicon technology was ready. That ship sailed and what we're left with is a 4x+, not a 5x. My 4x and cancer will most likely follow me to the grave which is why my son, the Sound Engineer, gets first dibs on anything and everything. For whatever reason US keyboardists don't understand the power and flexibility of the Korg PA4x. It's now 9 years old since release. This business will never be satisfied with decade level updates. I've been involved with it since the late 1970's and ladies & gentlemen, a decade is way too long.
