Extract MIDI notes from one clip (by track index and clip index) as pitch/start/duration/velocity tuples.

Heuristic suggestions about what looks unfinished in a set: missing instruments, empty MIDI clips, no master limiter, etc.

List clips on one track (by index) or every track (omit track_index).

List all tracks in an .als file with their kind, name, mute/solo state, and device count.

Summarize an Ableton .als file: tempo, time signature, track and clip counts.

Aggregate finishing suggestions for a set: missing instruments, empty clips, no master limiter, single-note placeholders, very-short clips.

Run key estimation and chord guessing across every MIDI clip in the set. Useful for a 'where am I harmonically' overview.

Create an empty MIDI clip in the arrangement timeline of a MIDI track.

Replace notes in an arrangement MIDI clip. notes is a list of dicts with {pitch, start, duration, velocity, mute?}.

Check whether the AbleMCP M4L bridge is running. Returns the bridge's ping payload on success, or guidance on how to install the device.

Continue playback from the current position.

Create an empty MIDI clip in the given session slot. length_beats defaults to 4.

Create a new scene. index defaults to -1 (append).

Create a new track. kind ∈ {'midi','audio','return'}; index defaults to the end. Returns the new track info.

Delete a clip from a session slot.

Delete a track by index. Use live_undo to recover.

Bridge environment info: storage/temp dirs and Live's UI language.

The currently selected track and scene in Live's view.

Current Live tempo in BPM.

Import an audio file into the Live project and create an audio clip. If scene_index is given, places the clip in that session slot; otherwise places it on the arrangement at start_time. Requires the .ablx extension bridge.

Whether Live's transport is currently playing.

List all tracks in the running Live set with kind, name, mute/solo/arm state.

Start Live's transport. Defaults to confirm=True.

Trigger Live's redo.

Rename a track by index.

Render the pre-effects audio of an arrangement track to a WAV file in the extension's temp directory. Returns the WAV path.

Replace the notes in a MIDI clip. notes is a list of dicts with {pitch, start, duration, velocity, mute?}. Existing notes are removed first.

Set Live's tempo (BPM, 20..999). Defaults to confirm=True.

Live transport state: tempo, time signature, playing flag, song position, track count.

Stop Live's transport. Defaults to confirm=True.

Trigger Live's undo. Reverts the last LOM-visible change.

End-to-end live flow: render audio from an arrangement audio track range, extract vocal guide, generate complementary melody, create a new arrangement MIDI clip, and write notes into it.

Estimate the key of a MIDI clip in an .als file using the Krumhansl-Schmuckler algorithm. Returns tonic, mode, and confidence.

Extract a monophonic guide melody from a vocal WAV file with a dependency-free pitch tracker. Returns notes in both seconds and beats (requires tempo_bpm).

Generate a complementary MIDI melody (not a duplicate) from guide notes in beat-space. Input note dicts: {pitch,start,duration,velocity?}.

Guess chords across a MIDI clip with a sliding window. window_beats defaults to 1. Returns time-aligned [{start,end,chord}] segments.

Per-clip note stats: count, range, density, pitch-class histogram.

Convenience one-shot: extract vocal guide from WAV and immediately generate a complementary MIDI melody in beat-space.

Make a timestamped copy of an .als file in /Backup/. Never modifies the source. Returns the backup path.

List timestamped backups for an .als file.
