Filters

Volcano 2 comes with four multi-mode stereo filters, which can be routed in almost every possible way, even per-channel and mid-side.

Every filter can be switched between low-pass, high-pass, and band-pass responses with 12, 24 and 48 dB/octave slopes and a staggering amount of eleven different high-quality filter characteristics that define the unique sound and overdrive of the filter. They range from smooth with moderate overdrive to raw, self-oscillating and over-the-top! All characteristics have been tuned very carefully, using our state-of-the-art FabFilter filter technology.

One set of filter controls is shared among all filters, which shows the parameters of the active filter.

To activate a filter, click one of the numbered filter buttons. The button for the currently active filter lights up and is connected visually with the filter controls section.
To bypass the active filter, click its filter button again. The first click activates the filter; once it is active, the filter button enables and disables the filter. When a filter is bypassed, the filter controls will look disabled, but can still be used to adjust the filter.
To add a filter, click the + button next to the last filter button. The newly added filter will copy most of its settings from the currently active filter.
To remove a filter, activate it and then click the Remove button at the top right of the filter controls section. If there is only one filter left, you cannot remove it.
Click the Presets button to save the current filter and routing settings, or to access previously saved section presets. Note that this affects all filters and the routing, not just the active filter. See also Section presets.

In the filters section, we applied our new what-you-use-is-what-you-see concept: you only get filter buttons for filters that you are actually using at the moment. Even the Routing button only contains the routing options available for the current number of filters!

When using L/R or M/S configuration, the amount of filters will always be 2 or 4. So when adding or deleting filters just one click will add or delete 2 filters automatically.

You can use the filters individually or combine filter characteristics to create your own sounds in any way imaginable. To experience the full potential of Volcano 2's filters, try it on some signals with rich harmonics (synth sounds, distorted guitar or complete mixes are good sources for filtering).
