Hi all, we're really happy to announce that version 2.5.6 of Control Surface Studio is now available.

You can download it either from the login screen inside CSS or by going to your personal 'My Downloads' page on the website. You will find a link to this page in top menu (when logged in).

Control Surface Studio can now generate working scripts for Ableton Live 11. Open the settings menu at the top of CSS where you will see a new option called 'Python Version'. Here you can select between 3 versions, Python 2.5, 2.7 and 3. Ableton Live 11 uses Python 3.

We've added better backward support for versions of Live which use Python 2.5 (before Live 9.5). This fixes issues which users were experiencing regarding broken scripts in these older versions of Live.

We also fixed an issue with the autosave functionality that was causing script and setting json files to become corrupted. This was causing scripts to disappear from CSS and in some cases the entire App layout was unresponsive.


  • Scripts can now be compiled for Ableton Live 11 (Python 3)
  • Ability to select Python version in settings menu
  • Support for multiple Python versions... 2.5 (Ableton Live < v9.5), 2.7 (Ableton Live > v9.5 and < v11) , 3.x (Ableton Live v11+)


  • Script generation for Ableton Live 9.2.3 (Python v2.5)
  • Multiple autosaves causing saved json to become malformed (scripts disappearing in App)
  • layout of 'Device Parameter Banking' menu

That's awesome! Was just approved as Live 11 Beta tester! Can't wait to try out all the new implementations.

Good day. When will the web version of Remotify be compatible with Live 11? I have a rather large script for a BCR2000 that I do not necessarily want to rebuild again with CSS.

Awesome work! I highly recommend this app to anyone who uses Live 10 and 11. Ability to Design your own controller template and then link it to any particular script you are working with is genius and I love it!
