Project files: why you can't open an Ableton set in Logic
A DAW project file is the recipe for your song: tracks, notes, plug-in settings, automation and pointers to your audio, saved in a format only that DAW fully understands. That is why an Ableton set will not open in Logic. To move a song, export stems and MIDI, try the open DAWproject format where it is supported, or work in a cloud studio where the project lives online.
