Changes the centre position of filter tracking across the keyboard range from the default position of 64 - middle C. For a position above middle C, click and drag from the display upwards. For a centre position below middle C, click and drag from the display downwards.
Select between linear and exponential filter tracking.
In linear mode, the filter difference between each key will be equal. In Exponential mode the tracking will get more pronounced higher up the keyboard range, leaving subtler variations in the central area.
