Get the mixer state (volume, panning and sends) for a track.

Each value is reported three ways: the raw 0..1 parameter value, the dB it corresponds to, and the string Live itself displays.

Parameters:

• track_index: The index of the track (ignored when track_type is "master")

• track_type: "track" (default), "return", or "master"

Set a track's volume fader.

Prefer db — Live's fader taper is non-linear, so the raw 0..1 value is not proportional to level (0.85 is 0 dB, 1.0 is +6 dB). Passing db resolves the exact fader position for that level using Live's own readout.

Parameters:

• track_index: The index of the track (ignored when track_type is "master")

• db: Target level in decibels, e.g. -4.0. Clamped to the fader range.

• value: Raw fader position 0.0-1.0, as an alternative to db

• track_type: "track" (default), "return", or "master"

Set a track's pan position.

Parameters:

• track_index: The index of the track (ignored when track_type is "master")

• value: -1.0 is hard left, 0.0 is centre, 1.0 is hard right

• track_type: "track" (default), "return", or "master"

Set one of a track's send levels.

As with volume, prefer db over the raw value. The master track has no sends.

Parameters:

• track_index: The index of the track

• send_index: Which send to set (0 is the first return track, A)

• db: Target send level in decibels, e.g. -12.0

• value: Raw send position 0.0-1.0, as an alternative to db

• track_type: "track" (default) or "return"
