Comparing sounds on Korg Nautilus(bottom) to Medeli AKX10(top)

Laptop, software didn t get along for the 1st minute, but it smooths out. Wear headphones to best hear subtle sonic differences. I picked like instruments at default settings(some with same names), the Medeli volume is maxed, where as the Korg isnt even at half. Nautilus is brand new to me, still learning to navigate. Got carried away, forgot I was recording lol.
