MIDI & DMX Mapping
Lumentrace supports two external input methods for control mapping: MIDI and DMX input. Both let you bind hardware controls to Lumentrace parameters.
What can be mapped
| Target | Type | Behaviour |
|---|---|---|
| Preset | Button | Applies the preset on a rising-edge trigger (value > 0) |
| Fixture attribute | Continuous | Maps the input range to the attribute's full DMX range. Attributes: intensity, pan, tilt, zoom, focus, iris |
| Fixture offset | Continuous | Maps the input range to the pan or tilt offset (±100%) |
MIDI mapping
Open Setup → Open Settings... → MIDI Remotes.
Setup
- Enable the MIDI toggle.
- Select your MIDI input device from the dropdown. Click Refresh to rescan devices.
- Click Learn next to a target, then move a control on your MIDI device. The binding is captured automatically.
- Click Clear to remove a binding.
Supported input types
- CC (continuous control): values 0–127
- Note On/Off: triggers on note-on (velocity > 0)
MIDI Pitch Bend is not supported.
DMX input mapping
Open Setup → Open Settings... → DMX Remotes.
Network configuration (required first)
DMX input requires a control universe to be configured in Network settings. Open Setup → Open Settings... → Network and set:
- Control Protocol: Art-Net or sACN
- Control Universe: the universe carrying the control signal
Save the network settings. The DMX Remotes page will show the configured protocol and universe.
Setup
- Enable the DMX Input toggle.
- Click Learn next to a target. Lumentrace takes a snapshot of the incoming frame.
- Move the fader or control on your DMX source. Lumentrace detects the channel with the largest change (threshold: 30 DMX units) and binds it.
- Click Clear to remove a binding.
DMX values 0–255 are scaled to the same 0–127 range used internally.
