Composition
Keep MAIN, PIP selection and source routing together. Draft position, size and scaling before one deliberate Apply.
iPhone + iPad · Local network
Live control,
without guesswork.
Compose layers, manage signal inputs and monitor a manufacturer-neutral Generic Link processor from one safe operator workspace.
State synchronized
One operational surface
Everything essential stays close to the operator.
Controls only appear when the connected endpoint declares support. No dead controls and no claims beyond the live capability contract.
⌗
Inputs
See signal, resolution and frame rate, then manage color, hot backup and EDID when available.
◫
Presets
Recall, save, overwrite and clear slots with schematic layer summaries and deliberate confirmation.
◉
Display & output
Operate freeze, blackout, test patterns, brightness, output format, sync, audio and transitions.
⌁
Monitoring
Track input health, output links, primary/backup roles, traffic and the freshness of every snapshot.

Full demo
Explore the complete interface and deterministic fault scenarios without hardware, an account or a cloud service.
Safe by operation
Read first. Unlock deliberately. Never duplicate a write.
LED Processor Control is built for a live environment where uncertainty must disable control, not hide behind a spinner.
1Synchronize
Read identity, capabilities and complete current state.
Read identity, capabilities and complete current state.
2Verify and unlock
Controls remain locked until the operator confirms the state.
Controls remain locked until the operator confirms the state.
3Serialize every command
Polling cannot collide with a write.

4Read back uncertainty
A timeout is never retried automatically.
A timeout is never retried automatically.
Compatibility, stated precisely
An open endpoint contract—not a hidden device library.
Generic Link
- Original JSON Lines protocol
- Reference Server and deterministic simulator
- Closed, fingerprinted profile imports
- No accounts, tracking or remote access
Third-party implementations
No manufacturer protocol, SDK, binary, firmware, brand asset, model profile or downloadable adapter is embedded in the app. A future adapter must pass legal, technical, bench and distribution gates first.
