VKB-SIM

I know from the official video that you can set up a button to switch between default curve and custom curve using the software.

But is there a way to tell which curve set I am using?

It seems the only way to make sure I am using the default curve is by pressing the SET button from the software, but it's rather inconvenient

So do you want to have a permanent curve applied to some axes or want to swap from default curve to a custom curve time to time?

I know how to swap between two curve settings using a button.
What I want to know is if there is a way to tell which curve setting I am using.

Yes, you could assign a LED to turn on or change color when the button that activates the curve is pressed. If you need further clarification let me know what joystick you have and which button you'd be using to activate the custom curve.
