Drop pixels by brightness — the loop-pack staple.
Keys out pixels by luminance instead of color: darks (or lights, via invert) go transparent and the layers below show through. Made for the white-on-black loop packs the VJ world runs on. Both thresholds are audio-bindable so the key can breathe with the music, and a matte view shows the raw alpha while you dial it in.

The controls you'll see in the inspector. Like every effect parameter in Visualz, each one is audio-bindable — route a frequency band, beat onset, sweep, or MIDI CC at it and it moves with the show.
Drop Luma Key on any of the four buses — clip, layer, track, or set — with pre-or-post placement and a per-effect dry/wet mix. Stack it with the rest of the chain freely; the engine batches everything into a single per-frame draw graph, and a chain you like can be saved as an FX preset and re-applied with one click.
