Band Mode

Turn once.
The room moves.

WhatThePDF sends performance-ready score pages directly from the Host Mac to every stand on the local network. The Host keeps control; musicians keep their focus.

  3. 03

    Count it in

    Turn from the Host or let musicians look ahead while the live page stays visible.

One room. Two roles.

One person runs the show.
Everyone else just plays.

Host and Player have different jobs by design: one screen opens the music and runs the room; every other screen stays focused on the score.

Built for the count-in

Music first.
Everything else backstage.

No scrolling document chrome during the song. The score fills the display, the active page is unmistakable, and the next turn is one key or pedal away.

PERFORMANCE VIEW The music fills the screen. Nothing competes with the chart.

One pedal. One page.

Exact turns from a keyboard, clicker, or MIDI pedal. No momentum. No surprise scroll.

♭

The right part.

Attach alternate PDFs by instrument so each musician receives their own chart at the same place in the show.

●

Ready before one.

Soundcheck shows which stands are ready, still caching, or need attention before the count-in.

Presenter

Run the set without touching the stage screen.

Keep the previous, current, and next pages on the Mac while the room sees only clean music. Blackout, lock, markers, and song changes stay with the person running the show.
