In the graphic below, the filters are cabled in parallel. If Filter Blend is set to 0, you’ll hear
a 50/50 mix of the source signal routed via Filter 1 and Filter 2, which is fed into the
mono input of the dynamic stage. There it can be panned in the stereo spectrum, and
then fed into the effects processor.
Filter Blend: Cross-Fading the Filters
You can cross-fade the two filters. When wired in parallel, you’ll find this quite obvious
to look at and understand: If Filter Blend is set to its top position, you’ll only hear Filter 1.
If Filter Blend is set to its lowest position, you’ll only hear Filter 2. In between these
positions, the filters are cross-faded.
More often, you’ll want to cable the filters serially. It should be noted that even in series
mode, it’s possible to cross-fade the filters! This is achieved through the use of
controllable side chains (bypassing lines). In this serial cabling scenario, the distortion
circuits controlled by the Drive parameter also need to be considered, as the distortion
circuits are positioned before or in-between the filters, dependent on Filter Blend. All
fades occur flawlessly, in very fine steps.
The Filter Blend parameter can be modulated dynamically in the Router!
Filter Blend and Signal Flow
No matter whether parallel or series filter configurations are chosen, a Filter Blend
setting of −1 always results in only Filter 1 being audible. A Filter Blend setting of +1 will
limit audibility to Filter 2. This is reflected in the user interface.
