Completely awesome song, love it!
Quite tricky / a lot of sampling work on the Nord, though - if you want to get very close to the sound
What I tried in MainStage with Dexed + TAL J-8:
The main rhodes-like and guitar-like stabs are most likely played on a DX7, the Synth Strings pad in the chorus could also be DX7, but also could be a Jupiter-8
The bass sound could be a MiniMoog, but can also be recreated with a Jupiter-8 for example
Bass sound: try "LadderBass", which should already be included in your Stage 3's sample lib, and adjust the filter

For the stabs, I've used the following in MainStage and plugins:
layer1: Dexed and "Rippedroas" patch, which sounds similar to the "FullTines" but has a softer, more resonant attack + Chorus FX!
layer2: Dexed 12String DX7 patch + Chorus FX
layer3 (Chorus only): TAL J-8 2 Saw oscillators, detuned by 12semis, and loads loads of Chorus FX
conclusio: for the main sounds (right hand), you should be fine with "DX Full Tines" in the Piano section + a detune Saw +12 in the Synth
