Brainsalt Backstage

Controls a Brainsalt Backstage media server over its show-control protocol.

Full Backstage documentation: help.brainsalt.com

Setup

In Backstage, open Settings → Remote Control and check Enable Show-Control Protocol (then Apply / Restart Protocol Server); leave its Enable Bitfocus Companion sub-option on. Enter the same host, TCP port (default 7400) and — if configured in Backstage — the auth token in this connection's settings.

Nothing else is required: all show-control entities are discovered automatically, with live feedback, variables and ready-made presets:

• Steppers — play/pause/stop/restart/bang/next, go to step
• Sequencers — transport, fade in/out, seek, jump, tempo, fade level
• Broadcast schedulers — enable/disable, force entry, clear
• Calibrators — align, black level, cancel, restore snapshots
• Audio outputs & matrix mixers — volume (global/per channel), mute
• NDI inputs — route sources to input slots
• Node endpoints — send values into the node graph, read values back

Custom typed controls (optional)

For show-specific controls, add CompanionIO nodes (UI category) to your Backstage node graph. Each one appears here as a typed control with matching widgets and presets:

Type	In Companion
Bang	trigger button
Float / Int	value display + increment/decrement (encoder-friendly, clamped to min/max/step)
Bool	toggle button with on/off feedback
Enum	next/previous + one button per choice, with active-choice feedback
String	text display / set with variables
Color	color picker + live color preview

Remote Control In/Out nodes and labelled datatype nodes (Bang/String/Float/Color/Int) are also available as plain value endpoints via the generic Node: Send Value action.
