Your tandas, on your phone.
A music player built for tango lovers and tango DJs. It plays the files you already own and understands the shape of a milonga: tandas, cortinas, and the pause between them.
Built around the tanda.
The tanda is the unit.
Not a playlist with a nickname. Build tandas from your library, keep the order you chose, and see the genre at a glance: tango, vals, milonga, each in its own color.
Milonga mode.
Plays tanda by tanda, with a cortina in between, and a short breath between tracks.
Cortinas, measured.
Thirty seconds at full volume, then a five-second fade. Both adjustable. Only tracks you marked as cortinas are used; nothing is cut short by accident.
A lock for the room.
In Milonga mode the controls are locked. Hold the amber ring to open them for a moment; they lock again on their own.
Two ways to play.
Milonga mode
For the night. Tandas in order, cortinas between them, the lock on.
Listening mode
For home and practice. Straight through, gapless, shuffle track by track.
For the night itself.
The things a DJ deals with at 1 a.m., built in.
- Your plan stays your plan.What actually played is kept as its own record of the night.
- Played before?If a track already played tonight, TandaBox tells you. The choice stays yours.
- When the night runs long or short.Add or move tandas live, or end the night earlier, and see the new end time at once.
- Emergency Cortina.One touch, chosen in Settings before the night: play it now or after the current track.
- Before you start.A one-page check before Milonga mode begins: battery, storage, missing files.
- A planned break.Mark an upcoming track to pause after it.
One family, three roles.
