Reply to Kontrol S2 Mapping.

Hey guys

I'm wondering if i can make a small addition to the ''Default'' S2 mapping, say i wanted to hold shift and move the Hi EQ to make it act as a filter or holding shift and moving the tempo fader to make it raise or lower the key of a song instead of the normal function that will only allow you to move the tempo on the S2 without it having effect on the song.

How can i do this? Do i need to go into the controller editor?
