Overview
Volcano's interface is divided into horizontal sections:

- Presets, undo and A/B
The Undo, Redo, A/B and Copy buttons at the top of the plug-in interface enable you to undo your changes and switch between different states of the plug-in. With the preset buttons, you can easily browse through the factory presets or save your own settings so you can re-use them in other songs.
- Interactive filter display
This is the graphic representation of the filter settings which allows you to drag all filters individually or simultaneously and control the filter settings with key combinations. See Interactive filter display.
- Filter controls
At the bottom of the display, the filter controls provide full control over all filter parameters. The filters offer a choice of low-pass, high-pass and band-pass modes and come with 11 algorithms that offer different filter characteristics. Each filter has a special delay option with short delay times up to 30 ms, creating all kinds of stereo effects. At the left of the filter controls, the routing button selects the routing of the four filters.
- Modulation button
The modulation button shows or hides the entire modulation section at the bottom of the interface. FabFilter Volcano 2 offers virtually unlimited modulation possibilities, but all this power might be a bit intimidating. That's why the modulation section is hidden by default, and you can look 'under the hood' when you want to tweak a preset or design your own.
- Source selection bar
The source selection bar shows all modulation sources at a glance and lets you easily scroll around and create new sources. FabFilter Volcano 2 offers XLFO, Envelope Generator (EG), Envelope Follower (EF), MIDI and XY Controller sources. See also Modulation.
- Modulation slots and sources
The bottom section contains the modulation sources. The modulation section in Volcano 2 is fully modular — but without the cables! We found a simple way to show you everything that is modulating, and what is modulated by what. Above each modulation source, the modulation slots show exactly what targets are modulated by this source and let you adjust the amount of modulation. You can very easily set up modulation connections with drag-and-drop. All in all, we think we made sound design easier and more fun!
- MIDI Learn, monitoring and input/output/mix
The bottom bar contains the MIDI Learn feature which sets up any MIDI controller to control any plug-in parameter. Next, we find various output options and mix buttons. See Output controls.
- Resize
The resize button in the lower-right corner lets you choose between normal and wide interface layouts. The wide layout provides more space for the modulation sources at the bottom of the interface. Most hosts support dynamic resizing of the interface; otherwise just close and re-open the interface window.
