Yes, to my knowledge, it will!
From Clavia's website;
"The Nord Lead 2X has the same characteristic sound and functions as the Nord Lead 2, except for some very nice improvements:
X-tra polyphony: The Nord Lead 2X comes with 20 voices polyphony - very useful when creating layered sounds, "power pads", awesome leads and booming basses. 20 voices are also very beneficial in sequencing situations when you use more than one sound at a time.
X-tra memory: The Nord Lead 2X comes with a large internal memory holding 4 x 99 user Programs, 100 user Performances and 4 x 10 user Percussion Kits plus 6 x 99 factory Programs and 3 x 100 factory Performances! The Nord Lead 2X is 100% patch compatible with the Nord Lead 2 which means that you can transfer sounds directly between the models via MIDI.
X-tra high resolution: The awesome sound in the Nord Lead 2X is refined even further thanks to the brand new, crystal clear 24-bit DACs running at 96kHz."
