For the Launchpad (and presumably the APC as well), you can set the position of the red box by calling ‘set_offsets’ on the “Session_Control” component of the control surface.
Save the following javascript in setRedBox.js
function setRedBox(x, y)
{
var api = new LiveAPI(this.patcher, ‘control_surfaces 0 components 1′);
api.call(‘set_offsets’, x, y);
}
And use from Max like this:
Copy all of the following text.Then, in Max, select New From Clipboard.

Note the javascript above makes two assumptions.
Firstly, you have your Launchpad set up as your first control surface.
Secondly, that the ‘Session_Control’ component of the Launchpad control surface object always has the path ‘components 1′. This *could* change if Ableton were to update the Launchpad remote scripts. You can work out the correct path of the ‘Session_Control’ component like so:
function findSessionControlPath()
{
var controlSurfaceIndex = 0;
var api = new LiveAPI(this.patcher, ‘control_surfaces ‘ + controlSurfaceIndex);
var count = api.getcount(‘components’);
for (var index = 0; index < count; index++) {
var path = ‘control_surfaces ‘ + controlSurfaceIndex + ‘ components ‘ + index;
api.path = path;
if (‘Session_Control’ == api.get(‘name’)) {
break;
}
}
post (path, ‘n’);
}
