The main window

The window has three areas: the header bar across the top, the middle area with channel strips and the arrangement timeline, and the right panel with regions and playlists. A separate floating File Browser window is available from the View menu.
Header bar
The header carries everything global:
- Link — enables Ableton Link, syncing tempo and transport with other Link-enabled software on your network.
- Tempo — the project tempo in BPM. All bar/beat positions derive from it.
- Position — the transport position in bars, beats and ticks; editable.
- Play / Stop / Record / Loop — the transport. Space toggles play/stop. Record arms the transport for recording (see Recording).
- Master meter and volume — a stereo level meter and the master output gain.
- A button to show or hide the right panel.
Channel strips
Each track shows its channels as strips on the left of the arrangement. Per channel:
- M — mute, S — solo
- Record — arms the channel for recording
- Monitor — routes the channel's input to the output while armed
- a level meter, gain and pan controls
Channel height is adjustable (micro / small / medium / large / huge) to fit many channels on screen — set it per channel with the height combo on the strip, or for the whole track by right-clicking the track header and choosing a size from the Waveform Size submenu. The same track-header menu also holds the Show Analysis toggles (see Analysis and Auto Edit).
Right-clicking a channel offers Copy selected channel(s) to new track.
Arrangement
The timeline. Tracks run horizontally; clips are drawn with their waveforms and can be dragged, trimmed and split. A bar/beat grid underlies everything (snapping can be toggled), and analysis results — segment boundaries, beats — can be displayed over the material.
Navigation: Cmd++ / Cmd+- zoom, ← / → page left and right, View → Follow Transport (Ctrl+F) keeps the view on the playhead.
Right panel
Two stacked lists, divided by a draggable resizer:
- Regions — every named region in the project. This is the pool of material you can place on the timeline.
- Playlists — the sequence of clips per track.
File Browser
View → Open File Browser opens a floating file tree (starting in your Music folder). Select one or more audio files and drag them into the arrangement to import them.
