Universe Monitor

Universe Monitor

The Monitor panel (Alt+3) provides a real-time view of all DMX data flowing through the system.

Universe List

The left side shows all active universes with protocol, address, source count, and active channel count. Art-Net universes show both the Net.Subnet.Universe notation and the 1-based absolute number (e.g. "0.1.0 (17)").

DMX Grid

The right side shows a 32×16 channel grid for the selected universe. Each cell is colour-coded by intensity — darker for low values, brighter for high values. The selected channel is highlighted in amber.

Click any channel to open the Channel History waveform view.

Filters

Filter	Options
Interface	Filter by network interface — useful when the same universe arrives on multiple NICs
Direction	Input only, Output only, or Both
Protocol	Art-Net, sACN, or Both

sACN Priority View

Toggle the Priority button to switch from DMX values (0–255) to sACN per-channel priority data (0xDD start code). Priority view uses a dedicated colour palette:

• Blue — low priority
• Green — default priority (100)
• Orange/Red — high priority (approaching 200)

Hover over a channel to see the exact priority value. Universe list entries carrying 0xDD data show a [P] tag. When multiple sources disagree on priority, both values are shown (e.g. "pri:100/150").

sACN Monitor Range

Configurable in the Monitor toolbar (default: 1024 universes). Controls how many sACN multicast groups are joined automatically for monitoring. Increase for large pixel-mapping or media server setups. Universes referenced by process engine inputs are always joined regardless of this setting.

Source Name Display

Each universe in the list shows the sender's name when available:

• sACN — the Source Name from the E1.31 packet header (bytes 44–107), cached per CID to avoid per-packet overhead
• Art-Net — the Short Name from the most recent ArtPollReply for that sender IP

The name appears in quotes after the interface tag, e.g. ⬇ sACN 1 [VLAN 200] "My Console" ● 42ch. Art-Net names appear after the first ArtPollReply cycle (~10 seconds).
