Keyboard Shortcuts & Feature Flags

Keyboard shortcuts

These work when the output window has focus.

Key	Action
`Shift+F`	Toggle fullscreen
`Shift+T`	Tap tempo
`Shift+F1`	Recall preset quick-slot 1
`Shift+F2`	Recall preset quick-slot 2
`Shift+F3`	Recall preset quick-slot 3
`Shift+F4`	Recall preset quick-slot 4
`Shift+F5`	Recall preset quick-slot 5
`Shift+F6`	Recall preset quick-slot 6
`Shift+F7`	Recall preset quick-slot 7
`Shift+F8`	Recall preset quick-slot 8
`Escape`	Quit

Feature flags

Add any combination to your Cargo.toml:

[dependencies]
rustjay-engine = {
    git = "https://github.com/BlueJayLouche/rustjay-engine",
    features = ["link", "prodj", "mtc", "ndi"]
}

Feature	Description	Extra dependency
`ndi`	NDI video input and output	NDI SDK installed system-wide
`link`	Ableton Link tempo sync	CMake ≥ 3.14; makes binary GPL-2.0+
`prodj`	Pioneer ProDJ Link tempo sync	None (binds UDP 50000/50002)
`mtc`	MIDI Timecode receive	None (uses existing `midir` dep)
`egui`	egui control backend (alt to ImGui)	None

Default features: ndi is on by default. All others are off.

To disable NDI (e.g. SDK not installed):

rustjay-engine = { git = "...", default-features = false }

Config file location

Per-app settings (MIDI mappings, last-used preset, OSC port) are stored in:

Platform	Path
macOS / Linux	`~/.config/rustjay/<app-name>.json`
Windows	`%APPDATA%\rustjay\<app-name>.json`

<app-name> is the string returned by your app_name() implementation.

OSC parameter paths

All declared parameters are available at:

/rustjay/<param-id>   f32

Default port: 7770.

Example — set intensity to 0.75:

/rustjay/intensity   0.75

Web remote endpoints

Default port: 3000.

GET  /params                   — all parameters (JSON array)
GET  /params/<id>              — single parameter value
POST /params/<id>  {"value": N} — set a parameter
WS   /ws                       — live update stream

Workspace crates

Crate	Role
