DualFilter filters out specific frequencies while allowing others to pass through.
MorphFilter lets you mix low-pass, high-pass, band-pass, and band-reduction filter effects, allowing for creative morphings or mixtures between two filters.
StepFilter is a pattern-controlled multimode filter that can create rhythmic, pulsating filter effects. You can also trigger pattern steps individually via MIDI.
ToneBooster is a filter that allows you to raise the gain in a selected frequency range. It is particularly useful if it is inserted before AmpSimulator in the plug-in chain, greatly enhancing the tonal varieties available.
WahWah is a variable slope band-pass filter that can be auto-controlled by a side-chain signal or via MIDI modeling the well-known analog pedal effect.
