The Mode Change Ableton Extension intelligently recognizes what key all of the MIDI notes are in your whole Live Set, and then allows you to change the key of all tonal material to a new key.
All MIDI data within clips residing on tracks that contain drum racks remain unaffected.
It’s best to do a save-as before you use this Extension, as all MIDI notes are changed.
A great way to use it is to have you MIDI clips playing before you open the extension, and use the ‘Preview’ button to real-time hear changes to your notes.
Results can vary and you may not always get what you expect, but that’s also part of the fun of it. Embrace the chaos.
Note, this Ableton Extension was created using version 1.0.0 of the Ableton Extensions SDK and works with Live 12.4.5 b3. It is intended for non-commercial and educational usage.
