MetaFilter from Waves is a multimode filter plug-in based on classic analog filters that can be used for a variety of sound-shaping applications. It features three separate modulators, including a 16-step sequencer, LFO, and an envelope follower with sidechaining.

The plug-in can be used to create effects such as filter sweeps, tremolo, auto wah, rhythm-based gating, ducking, modulation delays, and more. Using the MIDI learn function, parameters can be programmed to a MIDI controller allowing it to be used live as well as in the studio.
