Infinite drum rack macro map

Hey boys

About this post

I mapped it in a set (I used sampler instead of instrument rack because my project was taking 20minutes to open), and I'd like to know how would it be possible to use ONLY one knob for all selectors instead of 1 for each of 16 drum pad cell.

I bought Ill gates infinite drum rack aswell and he only uses 1 knob

Problem in my project: when I map sample selector for each 16 drum cells, on only one knob, it changes the sample for ALL 16 cells whicj is pretty gross as I use the drum rack for a step sequencer...

Here's my cfg, which should definately work...

/e I mean I could use bome to change channel on my MFtwister knob each time the drum pad is hit on my cntrlr but is there an easier/faster way?
