Light & lasers effect

Lasers Mid

Lasers Mid is a neon and laser effect in FRCTL, the browser VJ studio. Fast side lasers from two left and two right wall mounts.

Runs live on video, images, a camera or generated art. Stack it with any other effect, and route LFOs, envelopes or any of ten audio bands to its controls so it moves with the music.

What Lasers Mid does

Four wall mounts, two per side at a quarter and three-quarters height, each fire a tight fan of three beams straight across the frame. Both left mounts aim at one point on the right wall, the right mounts at its mirror, and that point scans top to bottom about twice a second at centre Speed, so the fans converge and scissor as rigid groups. Spread sets each fan's gap.

Using Lasers Mid

Where it works
Pick Mid for peak-time drops. It's the fastest of the three, twelve beams instead of ten, and they cut sideways across the subject at eye level rather than framing it from the corners.
With the music
The scan runs on the clock at a fixed rate, so match it to the track with Speed. B1 kick on Beams fattens and lengthens every beam, and an Envelope triggered by the beat on Spread splays the fans open on each hit.
Starting point
Beams at centre, Spread at a quarter, Speed at a quarter, so the four fans stay tight and the scan is slow enough to follow.
