Gotcha. I guess I was trying to understand why the button couldn't be subbed out for a variable resistor (assuming a variable resistor is what the CAB2 uses). I know I wouldn't get quilling on TMCC locos. But I thought that I could on Legacy locomotives.
I also really like the CAB1L. It's easy, light, comfortable. I can reach everything. I prefer it over the DCS app because I don't have to look down to see where I'm pressing.
