Touch sensing systems and methods employ a touch surface and a touch sensor. An array of electrodes of the touch sensor is configured to capacitively couple to a touch in proximity with the touch surface. Circuitry is coupled to each electrode via a channel and configured to sense signals present on the electrodes. The circuitry is configured to independently adjust a sensed response of each electrode. For example, the circuitry may be configured to adjust a gain of each channel, an offset of each channel, or a gain and offset of each channel.
