Practice apps show you notation. Backing tracks play audio. Nothing made a whole band's tab, notation, and lyrics move together alongside the real recording or synths... until BandCue.
Guitar Pro tabs and real notation. A synced YouTube recording. Join a Room, one leader, everyone following.
No app combined all three. Bands kept losing the count between takes or couldn't start at the same time.
Every part can carry its own timing against the same recording, so guitar, bass, and keys each land exactly where they should.
Lyrics scroll in time with the song, so singers finally have something to follow too.
One person controls play, pause, and seek. Everyone else's screen just follows.
See which bandmates are online and pull them straight into your room.
Queue the whole night, public or private, and move on without breaking sync.
