Plan or apply exact rack-chain volume, pan, mute, solo, and send levels using native ranges and guarded hierarchy state.

Plan or rename an exact rack chain with a guarded hierarchy snapshot. For return chains, name is a raw label; Live adds the return letter prefix. Use observed name for display, not verbatim restoration.

Plan or mute/solo an exact populated Drum Rack pad by MIDI note with a guarded rack snapshot. Does not assign sounds to pads.

Plan or reassign a Drum Rack chain to a MIDI pad note and optionally change its instrument output note. Occupied destinations layer chains rather than replace sounds.

Plan or apply guarded bounded changes to exact loaded-device parameters on an ordinary, Return, or Main track. Native Looper State writes targeting Record or Overdub are flagged as recorded-content mutations: restoring a previous parameter value does not restore captured audio.

Plan or request one exact native Looper State choice: Stop, Record, Play, or Overdub. Native execution rechecks the complete Looper, routing, and transport snapshot before writing State; result reports the immediately observed State parameter and whether it matches the target, not an audible or quantized-boundary outcome. Record/Overdub can mutate captured audio and cannot be rolled back by restoring a parameter value. This does not promise beat-scheduled execution; verify native quantization behavior separately.

Plan or request one exact native Beat Repeat Repeat choice, Off or On. Native execution rechecks the complete device, routing, and transport snapshot before writing Repeat and reports its immediately observed value. Does not promise beat-scheduled execution, a captured buffer, or an audible effect.

Plan or request one exact native Beat Repeat Grid display division from get_beat_repeat_performance_context.gridChoices. Ambiguous or unavailable display labels fail closed. Native execution rechecks the complete device, routing, and transport snapshot before writing; observed parameter equality is reported, not an audible or beat-scheduled result.

Plan or request one exact native Beat Repeat Interval display from get_beat_repeat_performance_context.intervalChoices. Native integer-position labels are mapped without assuming a quantized parameter or scheduled trigger. Ambiguous or unavailable labels fail closed; execution rechecks the complete device, routing, and transport snapshot and reports immediately observed parameter equality, not an audible result.

Plan or apply guarded per-note timing, velocity, probability, mute, and pitch changes by stable note ID on one exact Session or Arrangement MIDI clip.

Plan or apply guarded pitch correction of exact chromatic MIDI notes into the current Live scale. Direction is explicit; equal nearest choices require an explicit tie break. Existing in-scale notes are never changed.

Plan or stop Live playback immediately using the guarded panic operation.

Plan or start Ableton transport playback.

Plan or stop Ableton transport playback.

Plan or launch one exact Session clip slot.

Plan or stop one exact Session clip slot.

Plan or set the record-arm state of one exact track.

Plan or apply a guarded per-scene clip-launch quantization override from list_scenes. The global setting stays in song musical context; only the selected scene changes.

Plan or create a new groove in Live's Groove Pool with an optional name. Adjust its base grid and amounts afterward with set_groove; groove deletion is not exposed by Live's public API.

Read one track's native MIDI note routing (input/output notes and scale transposition) from its MIDIMap. Reports unsupported explicitly when Live does not expose it.

Plan or apply guarded changes to one track's native MIDI input/output note and scale transposition. Affects every clip launched on the track; does not change device-level or rack-chain note routing.

Read one track's native freeze state. On the tested Live 12.4.5, is_frozen is readable but has no setter, so freeze/unfreeze remain UI-only; Live's native error surfaces if a future version exposes the setter.

Plan or toggle guarded track freeze. On the tested Live 12.4.5 the native is_frozen property has no setter, so execution fails closed with Live's own error; the plan still binds the observed state so newer Live versions can adopt the write without contract changes. Freezing renders the track's live material to audio and mutates audible content until unfrozen.

Plan or apply guarded volume, pan, mute, and solo changes to multiple existing ordinary tracks in one confirmed step. Per-track values clamp to each observed native range; sends are unchanged.

Plan or stop every playing Session clip in one guarded step using Live's native stop-all action. Playback-only; does not delete or mute clips.
