  • Create own key switches with Ableton’s Instrument Racks or Effect Racks.
  • Export and import your presets and share them with other users.

  • Includes a virtual control pad for your key switches, an XY controller in the display to perform MIDI CCs and a piano which shows you the pitch range of your instrument.
  • Assign additionally an Automation Key to change on the fly between improvisation and automation.
  • The design perfectly integrates into the interface of Ableton Live.
  • Detailed online user manual with many illustrations and further tips in a growing knowledge base.

Knowledge Base



“Automate your articulations and MIDI CCs in orchestral compositions with Ableton Live’s automation envelopes in the Arrangement View!”


I originally created this patch for own purposes, because I did not find any satisfying solution for Ableton Live to manage in a comfortable and clear way the articulations of my VST libraries.

I love working with Ableton, but you either load all the articulations into seperate tracks and scroll through them until you get dizzy, or you work with provided key switches and memorize MIDI notes and CC numbers that not only vary from library to library, but are even inconsistent between its different instruments.

Multi-Clip Editing in Live 10 has been a great new feature to edit numerous tracks simultaneously and has definitely helped to make composing in Ableton more straightforward. But it still didn’t allow me to work in the way that I had in my mind.

Finally, I had some time in the end of 2019 between two projects and decided spontaneously to build my own solution in Max for Live. Euphoric to have finally found my long awaited workflow for orchestral compositions, and encouraged by some enthusiastic musician friends, the idea came up to develop the device in such a way that it would be accessible to anyone else looking for a more natural feeling way to play or edit multiple articulations of an instrument in a single track.

So I tried to imagine what other Ableton users would like to have included in this kind of device and released the first version finally in April 2020.

Over the last two years, the Keyswitch & Expression Map has become the daily companion of more than 400 musicians and composers worldwide. This has been a great compliment and motivation to further develop the KeySwitch & Expression Map. Thank you for your kind and inspiring feedback as well as your support. I hope that I was able to implement all your wishes in version 4.

If you have further ideas, you discover a bug or in case of any questions, please write me a message using the contact form.

I wish you much success for your projects!
