AV Toolkit
Read full descriptionHide full description
A field-diagnostics tool that shows, right on the spot, whether your OSC and Art-Net signals are actually getting through. Isolating a cabling issue takes forever, and when something breaks it's hard to tell whether it's your settings or the other end — AV Toolkit was built to cut down that on-site stress. ■ OSC Monitor Watch incoming OSC messages in real time to confirm signals are actually arriving. ■ Art-Net Monitor Check Art-Net traffic on the network to catch lighting-control issues early. ■ Network Scanner Scan the local network to see what's connected, without hunting for IP addresses by hand. ■ Test Signal Output (Pro) Send test signals yourself to verify the receiving end is working, even without a second device. No account required. AV Toolkit does not collect or transmit your data.
