The only issue is looping the signal chain from the Korg through the iPad and back or through depending on the destination. ‘How’ will depend on if it’s a lightning or USB-C connector.

My iPad keyboard is still my Line 6 Mobile Keyes 49 that came with a 30 pin cable for my 1st gen iPad. I had to use the Apple 30 pin to Lightning Adapter with my next few iPads and that worked great. Since it also has a separate USB 2 port, it connects to my current M2 iPad with an inexpensive USB-B to USB-C printer cable nowadays.
