Reply to Midi Fighter recording & juggling effect, please explain

Hi all,
I couldnt help but be in awe of the midi fighter mapping Ean demo'd on his recent vid, looks like a lot of fun!
I dont own a midi fighter but I'd like to have a go at mapping it to my MPD24. Most of the mapping was explained clearly and concisely apart from the cue mashing with the shift+rec button.

Is the effect being used the beatslicer? In advanced or chained?

Also, what do the cue buttons do once in shift+rec mode?

Cheers
