Im brand new on this forum, very interested by Nord keyboard for many years and now the time has come : I have enough money saved to acquire a (used) Nord Electro

I have a question, I searched over the forum and found some answers, Ive also read the manual but it's not very clear in my brain since I don't have the NE5 under my hands..
It concerns split functions and scenario 3, if I've understood correctly.
If I connect a midi keyboard to the NE5 :
Would I be able to play, for example, the upper part (Sample mode) on an external keyboard and play the lower part (maybe piano) on the NE5 ? This "Scenario 3" is not very clear for me on that point : does engaging scenario 3 means no sound from NE5 keybed, everything remains controlled by the MIDI controller ?
Will I be able to use pitch-bend wheel on the upper part with my controller?
Finally, does this “Scenario 3” mode, once engaged, is applied to all presets or can it be assigned to a specific preset?
For example:
PRESET A : split piano on lower part, sample on upper part < NO SCENARIO 3
PRESET B : piano on lower part played on the NE5, sample upper part played on my midi controller < SCENARIO 3 ENGAGED
PRESET C : same as preset A, everything played on the NE5
Etc..
Thank you !
