AV Toolkit: AV Troubleshooting

An AV troubleshooting tool that lets you confirm, on the spot, whether OSC and Art-Net signals are actually arriving.

Built to cut the guesswork out of live troubleshooting — is it your cabling, your settings, or the other side's gear?

■ Who it's for

Lighting, audio, and video techs — SR/PA engineers and lighting operators troubleshooting OSC and Art-Net gear on live event sites.

■ OSC Monitor

See incoming messages on any port in real time. Filter by address, and read "receiving" vs. "no signal" at a glance from a large status indicator.

■ Art-Net Receive Check

Watches ArtDmx packets on UDP 6454. Each Universe is shown as a card with source IP, fps, and channel count; tap to see all 512 channel values. Switch between a color-coded "Heatmap" view (dense grid, live-updating, see the whole universe at once) and a "RAW" view (channel number + value).

■ Network Scan

Scan devices on the same network and list IP addresses and response times. Pick any device to keep it under continuous ping monitoring.

■ Unlocked with Pro (one-time purchase, no subscription)

• Art-Net Test Send — manually send DMX values to a chosen Universe/channel to verify fixtures and nodes

• OSC Send Tester — send a message with a custom address and arguments to confirm connectivity

• Audio Test Tones — pink noise / 1kHz sine / L-R channel check for verifying PA wiring

• Video Test Patterns — full-screen color bars / grid / resolution pattern for checking projector and monitor hookups

Every receiver and sender can be started and stopped manually, and automatically stops when you switch tabs — so nothing keeps running unnoticed in the background on site.

A practical AV troubleshooting tool for lighting, audio, and video crews working on location.
