We use your email only for release notifications (if opted in) and to gauge install scale. No third-party sharing. Mac & Linux builds coming.
Trouble installing? See the SmartScreen / McAfee notes above — or try the Portable build (no installer wrapper).

⚠ Windows SmartScreen or McAfee may flag the installer

LMC is brand-new — Windows and most antivirus reputation systems haven't seen enough downloads yet to whitelist it. The installer is not malware; it's just unsigned by a paid commercial certificate authority (we're working on Microsoft Store distribution instead).

If SmartScreen blocks the file: click More info on the warning popup, then Run anyway.

If McAfee / Norton / another AV quarantines the file: open your AV's quarantine list, restore the file, and add an exception for the LMC installer. Or try the Portable build below — single-file, no installer, often passes through reputation filters cleanly.

Belt-and-braces: drop the file at virustotal.com to verify against 70+ engines — the vast majority give it the all-clear, and the few false-positives are the AVs we're working with to clear.

What's in it

Scene/Chase Builder

Faithful 4-channel mixer surface — Effect 1 ⊗ Effect 2 per channel, group/main mix, master strobe + gamma + 16-bit support. Scenes + Chases pop-out windows for fast show building.

30+ effects

Plasma, Fire, Kaleidoscope, Color Cycle, Gradient Sweep, Sparkle, Conway's Life, Starfield, Metaballs, Rain, Radar, Audio-reactive (Spectrum / Beat Pulse / Rings / VU Meter), Image/GIF, Video, Webcam, Screen Capture, Text + Star Wars Crawl.

Six output protocols

Art-Net, sACN E1.31, TPM2.net, Serial DMX (ENTTEC USB Pro), Glediator, HDMI/screen output. Run multiple simultaneously.

16-bit dimming

Optional 16-bit DMX output with γ=2.2 perceptual curve. Smooth low-end fades that 8-bit can't deliver — 65,536 levels per channel.

External Control IN

Art-Net / sACN DMX in, OSC in, MIDI Clock in / out, MIDI Time Code in, MIDI feedback out (light up your APC mini / Launchpad pads as scenes fire).

Show Mode

Full-bleed live performance surface — sectioned trigger grid, latch/flash modes, BLACKOUT + STROBE + FADE + Scene X-FADE controls, PIN-locked Performance Mode for kiosk gigs.

Text + countdown

Built-in $DAY / $MONTH / $MONTHWORD / $YEAR / $TIME / $COUNT placeholders, 50+ fonts, custom font upload, 5× super-sampled glyphs for clean LED-matrix rendering.
