Ableton Live Object Model (LOM) Skill

A comprehensive API reference skill for Claude Code that documents the Ableton Live Object Model (LOM) API surface for Remote Script development.

Covers the Cycling '74 Live 12.3.x LOM reference at the object/member level: all official LOM object pages/root paths and their documented children, properties, and functions are represented, with common Remote Script patterns and examples. This is not a verbatim mirror of every paragraph from the Cycling '74 docs.

Usage

Once installed, Claude Code will automatically use this skill when working with:

• Ableton Live Remote Scripts
• Control surface development
• MCP servers for Ableton
• Any Python code interfacing with Live's internal API

Example

from _Framework.ControlSurface import ControlSurface

class MyScript(ControlSurface):
    def __init__(self, c_instance):
        ControlSurface.__init__(self, c_instance)
        self._song = self.song()

        # Access tempo
        self._song.tempo = 120.0

        # Create a MIDI track
        self._song.create_midi_track(-1)

        # Fire a clip
        track = self._song.tracks[0]
        track.clip_slots[0].fire()

API Coverage

Coverage is audited against Cycling '74's LOM index:

• 45 official LOM API objects/root paths mapped to skill reference files, including this_device
• 0 missing API member names in the latest local audit (scripts/audit_lom_coverage.py)
• Children, properties, and functions documented with types, access modes, observable status, parameters, and return types where available
• Common Remote Script patterns and code examples throughout

See references/lom-coverage.md for the object-by-object coverage map.
