| Section | Description |
|---|---|
| Package Structure | Required files, metainfo.xml, classfactory.xml |
| Script Interface | Task lifecycle, factory functions, include_file |
| Host API | Host namespace — Classes, Engine, GUI, IO, Signals, etc. |
| SDK Files | CCL.JS, Engine.JS, Devices.JS, HostUtils, etc. |
| Context Object | editor, functions, iterator, parameters, track list |
| Objects | Event, Region, Track, Channel, Mixer, Time objects |
| Skin XML Reference | Known skin.xml element and attribute reference |
| Utilities | Color, tempo, level conversions; debugging tools |
| Scripts | Real-world script implementation examples |

| Limitation | Detail |
|---|---|
| No MIDI CC iteration | context.iterator, editor.selection.newIterator(), and activeRegion.createSequenceIterator() exposed only note events; CC/controller fields stayed undefined |
| mainTrackList availability | context.mainTrackList is undefined in MusicEdit |
| Selection is not undoable | Disable journaling before any selection operations |
| Piano editor quantize UI | Read-only via context.editor.quantize |
| context.iterator availability | May be sparse or unavailable depending on the active editor surface and selection state |
| Event time object mutability | event.startTime, endTime, lengthTime return snapshots — writing to .seconds or .musical has no effect. Use newMediaTime() + edit functions. |
| Bar Offset is visual only | editor.activeRegion.start and event.region.start return the absolute beat position and do not consider Bar Offset |
- Complete
skin.xmlelement and attribute reference. Still missing documentation.
