Reply to modifying instant gratification mapping and triplets

Hi,

Sorry if these questions have already been addressed in a previous post - I'm new to the community .
I was wondering how you modify the instant gratification mapping slightly so I can have a 16th note gater effect going on instead of the filter (on the bottom row)?

Second question: Is there any way to map a triplet beat roll effect? Because as far as I know, traktor only has your standard quarter, 8th, and 16th beat rolls.

Thanks

PS I'm using Traktor Kontrol S4 and Midi Fighter Classic
