Similarly, overdriving the filters can create distortion, and the envelope follower can be used to achieve compression. For example, every filter has a Delay setting ranging from 0-50ms - by modulating this, chorus and flanging can be achieved. Each modulator can be routed to one or more parameters by dragging and dropping, and each connection has its own slot in which you can manage the source, destination and polarity of the modulation.īy applying a little know-how (or using the supplied presets), you can also go far beyond the usual resonant filter sweeps. XLFOs can have up to 16 steps, with global and per-step glide settings, and each step can use a Sine, Linear or one of two Square curves.Īll this offers much more control than the original's LFOs, which couldn't manage a sine LFO. Volcano 2 displays the modulators on a scrolling panel, and it's possible to have up to six envelope generators, four envelope followers and six LFOs - or as Volcano 2 calls them, XLFOs. However, rather than being given a fixed number of modulators, you can add or remove them as you see fit. The host-syncable modulation system is superficially similar to that of FabFilter's Twin synth. The filters can be linked so that adjusting or modulating the cutoff frequency or resonance of one affects any others it's linked to - useful when creating stereo effects.

The last of these modes is pretty unusual for a filter plug-in, providing great potential for stereo image manipulation.
