Synchronize guitar tabs and playback over mutliple devices via websockets

synced-guitar-tabs

A simple synchronized guitar tab viewer that allows multiple people to see the same song and coordinate playing it. You need to run a small server (can be local) for web sockets to work. Each user simply opens the web app in their browser.

Build using alphaTab.
