No longer worth posting links as you can just type Korg PA5x into YouTube and find a boatload available.
Had a listen to some of the videos (Using a sound system and headphones) and the sounds are fantastic, and this combined with the editing facilities should allow you to get whatever you want from them.
The sounds no longer cut off when changing them is good (But as most other manufactures have had this capability for years, it’s not exactly ground breaking) but 160 note polyphony seems rather low in this day and age. (Should be good enough for arranger play though)
Extra inputs, will the user actually use them when there are so many top notch mixers (With effects) available for a reasonable cost.
As to the rest of the keyboard, for me it’s just meh, with nothing screaming at me saying try me out. (I will of course try it out at some time)
