Starting with Firmware Version 1.2.0, Moog One has had the ability to change its aftertouch curve. This means you can alter the relationship between physical pressure on the keys and the Aftertouch Amount.
To change the curve, press the SETTINGS button to the left of the large encoder knob. Under HARDWARE SETTINGS, choose AFTERTOUCH CURVE and then rotate the last soft knob to scroll through the different available curves.
The four options are: LINEAR, SQUARED, CUBED, and EXPONENTIAL. Each one gives a different feel to the Aftertouch response of the keyboard. Experiment to find the one that best fits your playing style.
