Macros to select and arm a range of tracks in Ableton Live 12.2 Session View

Okay, slight tweak: If we were using this to arm one specific track as follows:

// Bail out if Ableton is not running
if (!sf.ui.abletonLive.isRunning) throw `Ableton Live is not running`;

// Track Names
let tracks = ['MIX 1']

// Arm Each Track in `tracks`
tracks.forEach((track) => {
    sf.app.abletonLive.song.tracks.find(tr => tr.name.stringValue == track).arm.setValue({ value: true });
});

How could we update this script to move focus in the session to the first empty clip slot for that track? Or to record a new clip?

Hi @wolaud,

Sorry for the delay in responding to these ideas! I've been traveling this week, so I've been in and out a bit.

For this first idea, we can read the input level of a track, but only if that track is armed. So to accomplish what you are after, we can arm the track briefly, read the level, and then disarm it if the level is below a certain level.

This is how we would do this:

// Bail out if Ableton is not running
if (!sf.ui.abletonLive.isRunning) throw `Ableton Live is not running`;

// Track Names
let tracks = ['MIX 1', 'MIX 2', 'MIX 3']

// Arm Each Track in `tracks`
tracks.forEach((trackName) => {
    let trackToArm = sf.app.abletonLive.song.tracks.find(tr => tr.name.stringValue == trackName);

    // This version will toggle - you could change the value in line 15 to "True" if you want to always enable
    if (trackToArm && trackToArm.arm) {
        let currentArmState = trackToArm.arm.value;
        trackToArm.arm.setValue({ value: !currentArmState });
    }

    // If the Input Meter Level is less than 10% off full scale, disarm the track; 
    if (trackToArm.inputMeterLevel.invalidate().floatValue <= 0.1) {
        trackToArm.arm.setValue({ value: false });
    }
});
