Sometimes, simple stuff matters. DJ mixers like Pioneer’s DJM-800 have simple, single-knob low- and high-pass filters. Laptop software often doesn’t. Enter FZero, with his free and open source Single Knob Filter to fill the gaps. (Windows-only, built in SynthEdit, but it’s open source and schematics of the basic signal processing are available, if anyone wants to translate this to Mac.) Drop this into an insert in a tool like Ableton Live and go play.

It’s apparently a big improvement on an Ableton forum solution that used 127 different filter instances in a rack.
I’m aware of the goodness of Single Knob Filter thanks to the Aurora open source DJ mixer project (see yesterday’s write-up); they assign an instance of the plug-in on each of the Aurora’s two mixer channels. Aurora’s Matt originally had the SKF plug-in in their Ableton template, but I encouraged them to replace it with Ableton’s Auto Filter for cross-platform compatibility and ease. That said, for plain DJ filtering, this it the One True Knob.
Now, go forth and use it on some crazy experimental noise soundscape you’ve been working on, just to spite cliche.
