Component to toggle PID values?

I'm sure there's a standard component in there somewhere to do this but I can't figure it out at the moment.

For ridged tapping I set my spindle to low gear and use a button on the GUI with the gearchange component to rescale position and velocity (the encoder is on the motor, index is on the spindle). This works plenty fine, but since I use an 8i20 (torque mode drive) for the spindle the PID loop values are not sufficient for a different gear ratio at slow speeds.

Basically I need to use the same button I set low gear with to also change the Pgain value to a higher number. I realize I could probably use another gearchange component to scale the 2nd value, but that's a bit more than what's necessary I just have to change Pgain from 0.1 to 2.0 with the button.

Sounds like a job for a mux component.
If you only need to choose between one of two settings use a mux2.

If you might need different settings for more than one set of gear changes use mux_generic.

is what you want to do, Can maybe be incorporated in your button macro?

That's what I was looking for, thanks.

I wrote the "lincurve" component specifically for "something-dependent" PID terms. (though it has many other uses)

But mux might make more sense here if the dependency is switched rather than continuous.
