# Lighting Configuration
The Lighting page is where you assign DMX lighting clips to MIDI notes, record new clips, and configure the lighting output.
***
## Configuration Slot (A-E)
Five independent lighting configuration banks. Each slot has its own MIDI note-to-DMX-clip assignments.
* Click the slot name in the header to expand the slot selector
* Switch slots by clicking on any slot in the list
* Rename any slot by clicking the pencil icon (up to 30 characters)
* Switching slots prompts you to sync -- choose "Sync to Playback," "Not Now," or "Cancel"
* Switch slots during a live show via MIDI CC #119 on the **lighting** MIDI channel (values: 10=A, 20=B, 30=C, 40=D, 50=E)
* Lighting and Video slots are **independent** -- you can have Lighting on Slot C and Video on Slot A
> *For more on slots:* [*Configuration Slots (A-E)*](/6.-configuration/configuration-slots.md)

## Global Lighting Settings
### MIDI Channel
Select which MIDI channel (1-16) triggers lighting clips. Default is **Channel 3**. The dropdown excludes whichever channel is assigned to Video to prevent conflicts.
### ArtNet Settings
Displays the current **Ethernet IP** and **Subnet Mask** used for ArtNet output. This is configured in the [Ethernet & ArtNet Configuration](/7.-networking/ethernet-and-artnet-configuration.md), not on this page.
The MVP broadcasts ArtNet data on the Ethernet interface with support for **up to 16 DMX universes** (8,192 channels).
### Edit Mode
Toggle **EDIT MODE** to enable changes. When off, the page is read-only.
***
## DMX Assignment Grid
The main area contains **100 cards** (MIDI notes 0-99):
### Card 0 -- Blackout
Always present. Label: **"DMX 00 - MIDI: C-2"** with value "Black Out Clip" and hint "Sends zero to all DMX channels." Triggering Note 0 on the lighting channel loads a special blackout clip that zeros all 512 DMX channels across all 16 universes. This card cannot be reassigned.
### Cards 1-99
Each card shows:
* **Header**: DMX Clip number and MIDI Note (e.g., "DMX 01 - MIDI: C#-2")
* **File selector**: Autocomplete dropdown listing all DMX clips
* **Clear button**: Small X icon to unassign (Edit Mode only)
* **Currently playing indicator**: Green pulse animation on the active clip's card
To assign a clip:
1. Enable **Edit Mode**
2. Click the dropdown on any card
3. Select a DMX clip from the list
4. Click **Sync Changes to Playback** to apply
***
## Media Panel (Right Column)
### Sync Changes to Playback
After making assignment changes, click **"Sync Changes to Playback"** to push the new changes. Changes do not take effect until synced.
### Record New Clip
Unlike the Videos page where you upload files, the Lighting page allows you to record ArtNet data directly from your lighting console or software.
* Record Button: Click the **RECORD NEW CLIP** button to open the recording dialog.
> *For detailed ArtNet recording setup with lighting software or a lighting desk, see:*

> * [*Recording ArtNet -- Lighting Desk*](broken://pages/10510c154f78c5e783ca13d18a35f0f4cf92c263)
### Free Disk Space
Shows remaining device storage spacce.
### Unassigned Clips
Lists all DMX clips not currently assigned to any MIDI note in the active slot. Each item shows the clip name and file size. Clips can be deleted from here (with confirmation).
> **Note**: You cannot delete a clip that is assigned in other configuration slots. A dialog will list which slots reference the file.

## ArtNet Preview
The Dashboard includes an [ArtNet Preview](/1.-getting-started/the-mvp-dashboard.md#artnet-preview) fthat shows a real-time 512-channel grid of DMX values. Use this to verify your clips are sending the expected data:
1. Assign and sync a clip
2. Trigger it (via MIDI, keyboard, or timecode)
3. Open the ArtNet Preview from the Dashboard's Lighting trigger table
4. Select the universe you want to inspect (1-16)
5. Verify the DMX channel values are flowing and match your expectations
