Built for experimentation
A real creative tool,
not a static mockup.
The public demo exposes an unusually complete creative pipeline—including two generators, dual effects, advanced mixers, colorsets, live microphone analysis, image/video/camera inputs, modular mapping, cue sequencing, presets, diagnostics, recording, and a simulated WLED discovery experience—while keeping physical output disabled.
Audio and media
Use real microphone analysis, image upload, Blinkenlights playback, local screen capture, and a simulated OSC image stream.
Mapping preview
Test modular layouts, per-panel rotation and flip, serpentine wiring, global orientation, brightness, and panel guides.
Seamless WLED discovery
The desktop app automatically finds compatible WLED controllers on the local network and presents them for one-click connection.
WLED-ready output
Send visuals to WLED installations with reconnect support, brightness synchronization, realtime transport selection, and segment-aware mapping.
Show control
Sequence cues, run timed scene loops, tap tempo, trigger blackout, and preview MIDI or OSC control workflows.
Presets and recording
Save locally, import or export JSON setups, capture PNGs, record the live canvas to WebM, and randomize complete visuals.
Live diagnostics
Watch FPS, frame time, virtual pixel count, RGB channels, active audio source, and simulated output health.
