Roundtrip audio from Pro Tools to Ableton Live and back

This script shows how to copy the current clip in Pro Tools to the clipboard and switch to Ableton Live:

sf.ui.proTools.clipConsolidateAndCopyToClipboard();

//Undo - this makes sure PT still has the original, non consolidated clip
sf.ui.proTools.menuClick({ menuPath: ['Edit', 'Undo'], looseMatch: true });

//Switch to Ableton Live
var live = sf.ui.app('com.ableton.live');
live.appActivateMainWindow();

Then inside Live, you can just hit Cmd+V to import the audio.
Now add the effects you want, or sample whatever you'd like.

When you're done to render the result and send back to Pro Tools, use this script:

//Helper function to get a unique id based on the current date and time
function getUid()
{
    var d = new Date();
    return ('000' + d.getFullYear()).slice(-4) + ('0' + (d.getMonth() + 1)).slice(-2) + ('0' + d.getDate()).slice(-2) + '-' + 
        ('0' + d.getHours()).slice(-2) + ('0' + d.getMinutes()).slice(-2) + ('0' + d.getSeconds()).slice(-2);
}

//Find Ableton and store it in the "live" variable
var live = sf.ui.app('com.ableton.live');
if (!live) throw 'Live is null';
live.appActivateMainWindow();

//Invoke Export
live.menuClick({ menuPath: ['File', 'Export Audio/Video...'] });

//Wait for the Export Audio/Video dialog to appear
var exportDlg = live.dialogWaitForManual({ dialogTitle: 'Export Audio/Video' }).dialog;
sf.keyboard.press({ keys: 'enter' });

//Wait for the Save dialog to appear
var saveDlg = live.dialogWaitForManual({ dialogTitle: 'Save' }).dialog;

//Find the Audio Files folder of your open Pro Tools session.
//We want to store the rendered file inside that
var audioFilesFolder = sf.ui.proTools.mainWindow.sessionPath.split('/').slice(0, -1).join('/') + '/Audio Files';

//Give it a unique filename based on the current date and time
var filename = 'live-' + getUid() + '.wav';

//Store the complete path for later use
var path = audioFilesFolder + '/' + filename;

//Enter our folder name and wait for the save dialog to be ready for the filename
sf.keyboard.type({ text: audioFilesFolder });
sf.keyboard.press({ keys: 'enter' });
while(true)
    try { saveDlg.getFirstOf('AXSheet'); } catch (err) { break; }
sf.wait({ intervalMs: 200 });

//Type the filename and Enter
sf.keyboard.type({ text: filename });
sf.wait({ intervalMs: 50 });
sf.keyboard.press({ keys: 'enter' });

//Wait for the render to finish
while(true)
{
    sf.wait({ intervalMs: 50 });
    var t = live.get('AXMainWindow').title.value;
    if (!(t == 'Export Audio/Video' || t == 'Export Audio...'))
        break;
}

//Copy the file to the clipboard
sf.file.copyToClipboard({ path: path });

//Switch back to Pro Tools
sf.ui.proTools.appActivateMainWindow();

Now back in Pro Tools, you can hit Ctrl+T to spot the file from the clipboard.

Voilà !
