Touch Mode
Touch mode writes automation only while a fader or switch is touched or clicked with the mouse. When the fader is released, the writing of automation stops and the fader returns to any previously automated position.
With other control surfaces in Touch mode, writing of automation does not begin until the fader hits the pass-through point, or the previously automated position. Once you reach the pass-through point with the fader, or a non-touch sensitive rotary control, writing of automation begins and continues until you stop moving the fader.
