BallroomSync
[ 01 ] Multi-device music player — built for dance studios

One room. Every device in control.

BallroomSync turns a studio full of phones, tablets, and desktops into a single music player. Drive class music from your phone while the studio sound system plays from the master device — every screen shares the same queue, controls, and now-playing state.

[ 02 ] The console

One output,
many remotes.

The active master device owns audio playback, so the room sounds clean through the studio system instead of echoing from every phone. Streaming sources play from the master while every other screen shows the live now-playing state — and any device can take over with one tap.

[ 03 ] Capabilities

Built like a
studio console.

Everything an instructor needs mid-class, and nothing that gets in the way of running it.

F·01

Shared rooms

Every device in a room sees the same queue, the same now-playing, the same controls. Co-control playback from anywhere in the studio.

Rooms
F·02

One master device

Pick which device drives the speakers. The rest mirror it for control and visibility, and can take over when you promote them.

Audio
F·03

Shared control

Queue edits, transport buttons, BPM changes, and playback status flow through the room so every controller stays current.

Sync
F·04

Folder-tree library

Organize tracks the way you think — nested folders per dance, per level, per class. Share whole folders or your whole library, read-only or read-write.

F·05

Playlists with fades

Schedule a class as a timeline: per-song fade-in, fade-out, breaks, and filler between tracks. Set it once, run it every week.

F·06

BPM & tempo control

Automatic BPM detection plus pitch-preserving speed control. Set a target tempo per folder and every track snaps to it — without sounding chipmunked.

Tempo
F·07

Spotify & YouTube

Pull in tracks from Spotify and YouTube alongside your uploads. Streaming sources play from the master device with full metadata everywhere.

Cross-platform

One app on Windows, Android, iOS, and macOS. Sign in with Google or Apple and your library follows you to every device.

Platforms
[ 04 ] Protocol

Scan. Drive.
Dance.

From walking in to first beat in seconds — no cables to plug in, no laptop to babysit.

01

Scan the room QR

The studio desktop shows a QR code. Scan it from your phone to join the room and become a controller instantly.

02

Drive from your phone

Build the queue, set tempos, hit play. Big thumb-reachable transport controls designed to be read from across the floor.

03

The studio plays

Audio comes out of the studio's sound system while every other device stays in control. Hand the master role over at any time.

≤5ms
[ 05 ] Device-to-device sync target — studio LAN

Uploaded tracks play in lockstep. The sync engine targets five milliseconds or less between devices on your studio network — tighter than a single video frame.

One clock, one room, every speaker on the same beat.
