ofxOceanodeTimeline

Optional clips, automation and timeline editing for ofxOceanode.

Install this folder beside ofxOceanode in openFrameworks/addons. Use the matching extracted version of Oceanode core, and add ofxOceanodeTimeline to your app's addons.make. Regenerate existing projects with the openFrameworks project generator to refresh source files, include paths and addon flags.

#include "ofxOceanode.h"
include "ofxOceanodeTimeline.h"

void ofApp::setup() {
    oceanode.setup();
    ofxOceanodeTimeline::setup(oceanode);
    // Register/load your presets after attaching the timeline.
}

For a headless host, call ofxOceanodeTimeline::attach(container) and register lfoTrack yourself if needed; attachment forwards to the root host.

The root container owns the timeline service. Macro containers share that service. Repeating setup on the same host does nothing. Without attachment, Oceanode has no timeline window, publishing menus or automation processing. Calling getTimelineManager() without attachment throws an explanatory exception; linking code that calls it requires this addon.

The existing manager API stays available through oceanode.getTimelineManager() and container.getTimelineManager(). Existing timeline.json files, clip IDs, binding paths and LFO Track node names are unchanged. Timeline JSON is left untouched when saving a project with core alone. To use projects containing LFO Track nodes, attach this addon before loading them.

Includes timeline model and persistence, clip/lane editors, parameter publishing menus and badges, piano roll and instrument setup, BPM automation and timebase retiming, LFO Track, wave clips and scheduling lookahead. Shared transport, deterministic random utilities and backend scheduling registration stay in core. Node instrument/value-scale metadata remains available in core so instrument addons do not need a timeline dependency.

See timeline model usage and example-timeline (generate its project files with the OF project generator).

See architecture and editor extraction for component ownership and the path to modular lane editors.

Verification

From the Oceanode core folder:

python3 tests/integration_compile.py
python3 tests/integration_compile.py --timeline ../ofxOceanodeTimeline
python3 tests/transport_regression.py
python3 ../ofxOceanodeTimeline/tests/timeline_regression.py
python3 ../ofxOceanodeTimeline/tests/editor_regression.py
python3 ../ofxOceanodeTimeline/tests/attachment_regression.py

The runtime regressions use real OF parameters and JSON under ASan/UBSan; the editor suite also runs production editors with headless ImGui. Set OCEANODE_TEST_OF_ROOT to a compiled macOS OF tree if needed. OCEANODE_CORE_ROOT can override the default sibling core path. These checks do not verify visual appearance or exercise audio hardware.
