Use exponential map in serial mode
If you check this, the exponential map on the General tab will be applied to serial commands.
This lets you alter response without altering code. For example, if you didn't write the code that is sending the serial commands, you can use this option and the exponential map to customize the response (softening it up near the center, biasing it in one direction, etc.), no hassle.
If you have a Kangaroo connected, we advise leaving this option off.
