Filter Editing via "Mouse Movement" in the Graphics Display
A white dot in the frequency response display represents an active filter (BYPASS not engaged). Clicking with the left
mouse button on this dot and keeping the mouse button pressed down allows changing the filter's frequency by
moving the mouse to the left or to the right. Clicking with the right mouse button on the white dot and keeping the
mouse button pressed down allows changing the Q-values (if SLOPE is set to 12dB) of the filter.

FREQUENCY sets the cut-off frequency of the
high-pass filter.
0.4...100 The Q-value sets the quality and thus the
response of the high-pass filter with slope of
12dB/oct. This parameter is not available at
other slopes.
BYPASS switches the filter ON (not engaged)
or OFF (engaged), which allows for quick A /
B-evaluation of the actual effect that the
high-pass filter has on the sound.
