Auto Align how to use

Yes, I would love that. Thanks!

Hmm I mean I personally prefer one button to rule them all instead of hunting and pecking on the stream deck but to each their own. (Check that link for ones that will intelligently grab the first track in a selection and alight all others to that and so forth) BUT here's this twist:

At the top name your key Track array of tracks to cycle through looking for clips. I've put your two example tracks to start. make a selection of the material you want aligned and run the script. It will check the array of tracks for first track with clips in it and choose that as the KEY Track and run auto align to it.

//// DEFINE THE TRACKS YOU WANT TO CHECK THROUGH HERE

let keyTrackArray = ['DIA A 1', 'DIA B 1']

sf.ui.proTools.appActivateMainWindow();
sf.ui.proTools.invalidate();

///GET TRACK INFO ALL
let trckInfo = sf.app.proTools.tracks.invalidate().allItems.map(m => {
    let mappedProps = {};

    for (let prop in m) {
        const itemsToSkip = ["Parent", "FriendlyNodeName", "SupportsAutoUpdate"];

        if (!itemsToSkip.includes(prop)) {
            const lowerCasePropName = prop.slice(0, 1).toLowerCase() + prop.slice(1);
            mappedProps[lowerCasePropName] = m[prop];
        }
    }
    return mappedProps;
});


/**
 * Returns the first track in keyTrackArray that contains clips.
 * If none contain clips, returns null.
 */
function getFirstKeyTrackWithClips(keyTrackArray) {
    for (let i = 0; i < keyTrackArray.length; i++) {
        const trackName = keyTrackArray[i];

        // Select the track
        sf.app.proTools.selectTracksByName({ trackNames: [trackName] });

        // Fetch clip info
        const clipInfo = sf.app.proTools.getSelectedClipInfo();

        // If this track has clips, return it
        if (clipInfo.clips && clipInfo.clips.length > 0) {
            return trackName;
        }
    }

    // No tracks had clips
    return null;
}

function autoAlignToTrackWithClipsFromArray(keyTrackArray) {
    //// Get Selected Tracks as Name Only String Array
    let slctdTrcks = trckInfo.filter(track => track.isSelected === true).map(track => track.name)
    //// Get Keytrack from Array with Clips
    let targetKeyTrack = getFirstKeyTrackWithClips(keyTrackArray);
    
    //// Reselect orginal tracks for aligning
    sf.app.proTools.selectTracksByName({trackNames : slctdTrcks})

    ///Check Status of Auto Align
    const aApostIsOpen = sf.ui.proTools.windows.whoseTitle.is("Audio Suite: Auto-Align Post").first.exists
    if (aApostIsOpen) {
        sf.ui.proTools.windows.whoseTitle.is("Audio Suite: Auto-Align Post").first.elementRaise();
    } else {
        sf.ui.proTools.audioSuiteOpenPlugin({ category: "Other", name: "Auto-Align Post", });
    }

    /// Define Auto-Align Window
    let win = sf.ui.proTools.firstAudioSuiteWindow
    /// Set Processing Options

    win.audioSuiteSetOptions({ processingInputMode: 'ClipByClip', processingOutputMode: `CreateIndividualFiles`, });
    const sideChainButton = win.popupButtons.allItems[4]
    
    /// Set Sidechain to Target Key Track
    if (sideChainButton.title.value != slctdTrcks[0]) { sideChainButton.popupMenuSelect({ menuPath: [targetKeyTrack] }) };
    
    /// Waif for computers that are too fast
    sf.wait({ intervalMs: 100 })

    /// Render Auto-Align
    win.audioSuiteRender();

    /// Wait For Render to Finish
    sf.ui.proTools.waitForNoModals();
    
    /// Re-Close Auto Align if it was Open
    if (!aApostIsOpen) { win.windowClose({}, `Could not find Audiosuite Window`); }
}

autoAlignToTrackWithClipsFromArray(keyTrackArray)

Create a new Script and copy this entire script into it. Give it a button and give it a run. From here if you'd like multiple instances of this, the best way is to template it so you don't have to create dozens of copies. @Kitch remind me where the template walkthrough is?

But basically on line 3 you can see

//// DEFINE THE TRACKS YOU WANT TO CHECK THROUGH HERE

let keyTrackArray = ['DIA A 1', 'DIA B 1']

You would change your keyTrackArray to be the tracks you want checked for that version of the button.

Here's one that skips all this and JUST does one fixed track that you can change via Template or simply making many many duplicate copies of the script. (I highly encourage you to watch the template walkthrough as it will be very useful on your overall Soundflow journey.

//// CHANGE YOUR SINGLE TARGET TRACK HERE :

let keyTrack = 'DIA A 1'

sf.ui.proTools.appActivateMainWindow();
sf.ui.proTools.invalidate();

///Check Status of Auto Align
const aApostIsOpen = sf.ui.proTools.windows.whoseTitle.is("Audio Suite: Auto-Align Post").first.exists
if (aApostIsOpen) {
    sf.ui.proTools.windows.whoseTitle.is("Audio Suite: Auto-Align Post").first.elementRaise();
} else {
    sf.ui.proTools.audioSuiteOpenPlugin({ category: "Other", name: "Auto-Align Post", });
}
/// Define Auto-Align Window
let win = sf.ui.proTools.firstAudioSuiteWindow
/// Set Processing Options
win.audioSuiteSetOptions({ processingInputMode: 'ClipByClip', processingOutputMode: `CreateIndividualFiles`, });
const sideChainButton = win.popupButtons.allItems[4]
/// Set Sidechain to Work Track 1 if It's not set
if (sideChainButton.title.value != keyTrack) { sideChainButton.popupMenuSelect({ menuPath: [keyTrack] }) };
sf.wait({intervalMs : 100})
/// Render Auto-Align
win.audioSuiteRender();
/// Wait For Render to Finish
sf.ui.proTools.waitForNoModals();
/// Re-Close Auto Align if it was Open
if (!aApostIsOpen) { win.windowClose({}, `Could not find Audiosuite Window`); }

As you can see this one is very simple just change the single KEY TRACK at the top and it will use that Fixed one accordingly. Less hoops to jump through for sure.

You might enjoy this one too,

Select any number of tracks and SF prompts you to pick the Key Track from a list, it will then process the others to that track.

Actually you may like this one the best if you're using a StreamDeck
