  • .als (Ableton Live Set) : this is the extension used whenever you save a live set. It is the core of your project, gathering information about your song, the structure of your beat, your clips/scenes arrangement, the path to the samples… It is also used for templates as it contains the same kind of information.

  • .alp (Ableton Live Pack) : this is basically a compressed version of an Ableton project, meaning it contains both the live set and the related content (back ups, samples…).

Data related

  • .alc (Ableton Live Clips) : this is a way to store session clips information. It can be both an audio or a midi clip. For midi clips, it saves as well everything from the channel strip (intruments, effects…).

  • .agr (Ableton Groove) : this contains MIDI information concerning rythm. It is used to modify the timing of MIDI clip elements.
.agr example
  • .ams (Ableton Meta Sound) : this is the format used to export Operator generated waveforms. Those can then be reloaded inside Operator, but also into Sampler, Simpler or an audio track.
