Maestronom Cast

One-click launcher for Maestronom Cast: stream this computer's audio to your phone for live guitar scale detection.

Maestronom Cast turns your computer into a second screen and audio source for the Maestronom guitar app on your phone. Click the icon to open the Cast companion at maestro.codrlabs.com — or jump back to it if it's already open, so an active streaming session is never duplicated or lost. From there: • Pair with your phone by scanning a QR code — no accounts, no setup. • Stream this computer's audio to the phone for live guitar scale detection: play along with a backing track or lesson on the laptop, and the phone lights up the scale on the fretboard. • Mirror the fretboard on the big screen and control it from the phone. Everything happens over your own Wi-Fi — audio never leaves your local network and nothing is uploaded to the internet. Requires the Maestronom app on your phone and Chrome or Edge 147 or newer (uses Local Network Access to reach your phone directly).
