Full session snapshot from Live: tracks, clips, tempo.

Realtime transport state from telemetry: playing, tempo, bar/beat, levels. Cheap — use this for 'where are we in the music' instead of get_session_info.

Start Live's transport.

Stop Live's transport.

Set the session tempo in BPM.

Save the current Live set.

Check both channels to Ableton: TCP command port and UDP telemetry.

Map decks A and B onto Session View track indices and persist the mapping.

Current deck mapping, what's playing on each deck, and transport state.

Load an audio file into a deck's clip slot (does not start playback).

Fire a deck's clip. quantize='next_bar' waits for the downbeat via telemetry; 'global' fires immediately and lets Live's launch quantization align it.

Stop the clip playing on a deck.

Set a deck's fader (0.0–1.0, where 0.85 is 0 dB).

Beat-synced crossfade: fire the incoming deck on the next bar, then ramp the incoming deck up and the outgoing deck down over bars bars.

Kill (or restore) an EQ band on a deck. Needs an 'EQ Three' device on the deck track. band: low | mid | high.

Set a PERF-rack macro on a deck by name (e.g. 'Glitch', 'Space', 'Crush'). value 0.0–1.0.

Ramp a PERF macro over N bars (a filter sweep, a building glitch, a riser). direction 'up' ramps 0→1, 'down' ramps 1→0. With release=True the macro snaps back to 0 at the end (classic build-and-drop).

Punch a PERF macro to intensity for N bars, then cut it — glitch rolls, echo stabs, one-bar granular washes.

Zero all PERF-rack macros on a deck (clean slate). Works with renamed macros.

List devices (and their indices) on a deck's track, so FX tools can be pointed at the right rack/plugin.

Dump a device's parameter list (names, values, ranges) on a deck's track — for exploring a plugin (Serum2, Infiltrator, ...) before automating it.

Set any raw device parameter by name on a deck's track (escape hatch when a macro doesn't cover it).

List analyzed tracks in the crate (title, BPM, key, energy).

Rank crate tracks that mix well next: BPM within ±8%, Camelot-compatible key, energy 'up' | 'down' | 'hold'. Give either the current file path or bpm+camelot.

Load a crate track onto a deck; with match_tempo=True also set Live's tempo to the track's analyzed BPM (use when starting a set, not mid-mix).
