The interactive filter display gives an overview of the filter parameters and makes it very
easy to adjust multiple filter parameters simultaneously. The vertical lines in the background
represent a logarithmic scale that correspond to the actual filter frequencies.
Drag a filter dot to adjust the Frequency and Peak
parameters for that filter.
Drag the link dot between filter 1 and 2 to adjust both filters
Shift+click a filter dot to toggle between the different filter slopes.
Ctrl+click (Command+click on Mac) a filter dot to toggle between the
different filter responses.
When holding down the Alt key while dragging a filter dot, the other filter will
change accordingly, as if you where dragging the link dot.
Holding down both the Alt+Ctrl keys (Alt+Command keys on Mac) while dragging
a filter dot will adjust the two filters while fixing the link dot in the center, so the other
filter will 'mirror' the changes.
Of course, all changes made in the filter display can be automated!
You can connect a MIDI controller to either the frequency or the peak adjustment of the
link dot with the MIDI Learn feature.
