Ableton Live user? Stop with the Autofilter. Waves' Metafilter is an excellent, more powerful alternative with built-in delay line and a 16 step sequencer. Noah Pred from Ask Audio shows how to make the most of it.

Ableton Live's Autofilter is a fantastic filtration tool for utilitarian purposes, though the modulation options may leave something to be desired. For those seeking a more full-featured filter option, Waves' Metafilter provides a rich comb filter, dynamic levelling, built-in delay line, and 16-step sequencer along with standard LFO and envelope modulators, stereo spreading, bit crushing, and parallel processing—all delivered with Waves' signature sumptuous sound quality. How to make the most of it in Ableton Live?
Configuring Metafilter
In Live's device view, click the reveal toggle to show the Configure button—then click it to open the Metafilter GUI. Now I can add parameters to be automated, modulated, or controlled in Live by simply clicking them in Metafilter. In this case, I'll add Delay Feedback, Rate, and Dry/Wet mix, LFO and Sequencer Sync rate, Filter Frequency, Drive, and Spread amount.

Now that all the parameters have been added, I'll click Configure again to exit configuration mode, and the sliders are now available for automation. The thing is, Metafilter provides such an extreme range of character that using the full range of these parameters could prove problematic—speaker damage and hearing-wise.
To address this, I'll select the Metafilter device and use Command-G (Mac) or Control-G (Windows) to group it to a rack. Once this is done, I can right-click on the parameter sliders and assign them to a Macro dial.

In this case, I'll assign the Cutoff and Drive to Macro 1, Delay Rate and Stereo Spread amount to Macro 2, LFO and Sequencer Rate to Macro 3, and Delay Feedback and Mix to Macro 4. Before going further, it might be smart to rename them with some sense of what I'm planning, which will become evident soon enough.
