Your guide through the circles. Virgil puts the routing matrix for your Dante-enabled audio network on your iPhone or iPad. Walk the room, stand at FOH or backstage, and patch, check and adjust devices without a laptop or extra hardware. PATCH FROM A GRID YOU ALREADY KNOW • Transmitters across the top, receivers down the side. Press and hold where they meet to patch or unpatch, so a stray tap never changes your show. • Finger-sized boxes, a crosshair that lights up the row and column you're touching, a filling ring while you hold, and haptic confirmation on iPhone. • Tap the + where two devices meet to open both, or hold it to patch 1:1 in one move (channel 1→1, 2→2…). • Expand or collapse everything in one tap. • Pinch to zoom out over a big system, search to filter by device name. • Green means connected. Amber and red flag trouble, with the reason. • Stays in sync: when someone patches from Dante Controller, Virgil updates on its own. • Clock and Events lights in the corner: green means all good. Tap Clock for every device's clock status, or Events for a log of what changed since you opened the app. DEVICE CONTROL Long-press any device for its info and settings: • Model and IP, identify (flash the LEDs to find the box in the rack) • Rename devices and channels, or reset them to factory names • Manufacturer, firmware, sample rate and bit depth • Latency • Analog input and output levels on AVIO adapters • Clock role and sync status, plus preferred leader • Reboot, with confirmation PRESETS • Save the routing for a show and recall it later. Virgil shows exactly what will change before it touches anything. BUILT FOR THE WORK • Talks directly to devices on your local network. No account, no cloud, no ads, no tracking. • Finds devices quickly and reliably over multicast, with a clear message if your network blocks it. • Remembers your devices, and Refresh scans the network for them when Wi-Fi blocks discovery. • Handles busy Wi-Fi gracefully and tells you when the network drops a reply instead of hanging. • Keeps the screen awake while you work (switchable). • Tells you what to check when no devices show up. • iPhone and iPad, portrait or landscape, iOS 17 and newer. • Works with VoiceOver: every box and header is described, double-tap-and-hold patches, and every action is on the Actions rotor. GOOD TO KNOW • Your iPhone or iPad must be on the same network as the Dante primary interfaces, and Virgil needs Local Network access (iOS asks the first time). • Supports both the classic and newer (ARC 2.8.15) Dante control protocols. • Devices enrolled in Dante Domain Manager aren't supported.

Verdict
The clearest difference is update cadence: Virgil at every 2 weeks against 20.12TT's every 6 weeks. 20.12TT's advantage is iOS requirement (9.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
