Read DMX Value

Sample a single DMX address and print its current value to the System Monitor via Printf().

function Main
(): void {
	const universe
 = 1;
	const address
 = 5;

	// Read the live DMX value (0..255).
	const value
 = GetDMXValue
(universe
, address
);

	Printf
(`DMX ${universe
}.${address
} = ${value
}`);
}

export = [Main
];

Notes

GetDMXValue(universe, address) returns the current output value (0–255). Returns 0 if the address is unpatched.
Printf() writes to the System Monitor (not the command-line history). Open it from the MA3 GUI's Settings → System Monitor — or run the plugin via Plugin "<name>" from the command line and the line shows up immediately.
Continuous sampling: a one-shot Main() snapshots once. For a live readout, wrap the body in a while loop with a coroutine.yield() and bind the plugin as a scheduled task, or read from the Execute() entry point each tick.
Patched fixtures: this reads the raw DMX output, not the channel's logical value (intensity %, position, etc.). For attribute-level reads, walk Patch() and ask the fixture for its current channel state.
