Touch remote

The remote is a page for tablets and phones that plays the show: the launch grid, scenes and faders. It doesn't edit anything.

Connect a device

1. Start the engine so that other devices may connect. The desktop app already does; the headless server needs --bind 0.0.0.0.
2. Click Tablet in the header. It shows the address and a QR code.
3. Open the address on the device, or scan the code.

The engine also announces itself on the network, so http://dmx-engine.local:7400/remote works too (--mdns-name changes the name).

There is no login. Anyone who can reach the engine can play it, so only open it to networks you trust.

On an iPad, Share → Add to Home Screen makes the remote open like an app.

What it does

• Launch buttons flash the moment they're tapped; panning the grid from a button doesn't flash it. Hold buttons (momentary clips and their scenes) don't pan the grid, so a hold that drifts a little keeps playing; pan from another button. The scene launched last keeps an accent edge, so it's clear where the set is.
• Faders follow a finger from where they are, so a stray touch can't make a level jump.
• Tempo opens a sheet for changeovers: switch between manual tempo and following the audio, sync to the detected tempo, fine-tune the BPM, tap, mark the first beat of a phrase, and nudge the beat earlier or later. See Tempo and audio.

When the screen locks or the page goes to sleep, the remote loses the engine for a moment. It reconnects by itself, within a couple of seconds of waking; until then it says Reconnecting… and the grid is dimmed and ignores taps. A button held down when the screen locks is let go.

The remote shows the live show even while a computer is in blind mode. The edit lock applies to it as to every window.
