Automating ARA Process

This should get you started. It's a template to put an ARA or Elastic Audio plugin on selected tracks. You will have to make a preset for each Plugin you want to use. Gonna make a searchable one, but havent gotten to it yet.

const elasticAudioARAPluginName = event.props.elasticAudioARAPluginName

/**
 * @param {object} obj
 * @param {string} obj.plugin
 */
function setElasticAudioPlugin({ plugin }) {
    const track = sf.ui.proTools.selectedTrack;
    const elasticAudioOrAraPlugInSelector = track.popupButtons.whoseTitle.is("Elastic Audio or ARA Plugin selector").first; 

    elasticAudioOrAraPlugInSelector.popupMenuSelect({
        menuPath: [plugin],
        isOption: true,
        isShift: true,
    });
}

sf.ui.proTools.appActivateMainWindow();

setElasticAudioPlugin({
    plugin: elasticAudioARAPluginName
});

sf.ui.proTools.mainWindow.invalidate()

Here is a list of all the plugins (with correct naming, current as of today):
Polyphonic
Rhythmic
Monophonic
Varispeed
elastiquePRO
X-Form (Rendered Only)
Acoustica
Auto-Align 2
DynAssist
Melodyne
RePitch Elements
RX Spectral Editor
SpectraLayers
VocAlign 6 Standard
WaveLab

if you're unfamiliar with making a template. first choose script, then convert to template. Then create a property called Elastic Audio ARA Plugin Name with type "string."

This script will do all selected tracks at once. There is plenty of code floating around this site to set your script up so it will cycle through one track at a time.
