Reply to nanoPad Beatmasher effect

So I am trying to make a beatmasher effect just like the one that is on the MF Instant Gratification TSI, however I can't figure out exactly how it is done even after looking over the MF TSI.

Mapping has never been my strong point, if you guys could help me out by explaining what I need to do for each of the 4 buttons I am sure I can figure out the mapping from there, hopefully; I'm just not sure what parameters and commands I need to actually get it to function like Ean's.

Here is the video for reference, the beatmasher is at 1:20.
