OSCILLA

Oscilla is an open-source platform for creating and performing animated, cue-driven graphic scores in the browser. Scores are authored as SVG documents and executed as synchronized, networked performance environments.

Oscilla integrates timing, animation, media control, and OSC output into a single browser-native score engine.

Documentation

oscilla.cc/docs

The documentation includes:

• Complete cue reference
• Animation and transformation syntax
• Authoring workflow (Inkscape to browser)
• System architecture
• Cheatsheets and examples

Source Code

Oscilla's source code is hosted at git.kompot.si/rob/oscilla.

Core Cue System

Oscilla uses a cue-driven execution model. Cues are embedded directly in SVG IDs and are evaluated in real time during score playback.

Available Cue Types

Timing & Navigation

• pause() — pause playback
• stop() — halt playback
• nav() — navigation and mode control
• page() — page-based score navigation
• stopwatch() — time display and control
• metronome() — tempo reference

Media & Sound

• audio() — audio file playback
• synth() — browser-based synthesis
• video() — video playback

OSC & External Control

• osc() — OSC message output
• oscCtrl() — OSC routing and control

Animation

• scale() — uniform or non-uniform scaling
• rotate() — continuous or stepped rotation
• o2p() — object-to-path traversal
• color() — color cycling and sequences

Interaction & Structure

• button() — interactive UI elements
• controlXY() — multitouch XY control pads
• propagate() — propagate cue state
• reuse() — reuse cue definitions
• text() — timed and sequenced text
• fade() — fade visual or UI elements
