To summarize, Waves MetaFilter is a simple but versatile multi-mode filter. It’s a shame that the included modulation sources can’t modulate other FX parameters apart from Delay Time. The distortion is equally useful, especially if you’re looking to add some fatness and grit to bass sounds. The delay module is my favorite MetaFilter feature, as it works like a charm for filtered slapback delays. The effects section expands MetaFilter’s sound design capabilities even further.

So, the plugin can also work as a tremolo, a faux sidechain compressor, and more. It turns the Cutoff knob into a volume control and lets you use MetaFilters modulation sources to automate the volume. MetaFilter offers five filter modes, including low-pass, high-pass, notch, band, and comb filters. The envelope follower is useful for processing percussive instruments, while the LFO offers another way to animate the filter and add movement to static sounds.Īll this modulation talk made me forget to mention the filter itself. The other two modulation sources are equally simplistic. You can connect it to the Cutoff, Resonance, and Delay Time, parameters, allowing for some interesting sound design escapades. Things get more interesting if you use the sequencer to modulate multiple targets. Despite its simplicity, the sequencer is handy for adding movement to the filter.

The step sequencer is a straightforward 16-step design with an adjustable rate, swing, and host tempo sync. It also features a delay module, distortion, and a stereo widener. MetaFilter is a multi-mode resonant filter plugin with a built-in step sequencer, envelope follower, and an LFO. Waves Audio and ProducerGrind offer the MetaFilter ($149 list price, $29 sale price) plugin as a FREE download for a limited time.
