You can resize tracks in Ableton Live using several methods, depending on whether you want to adjust a single track or multiple tracks in the Arrangement View.
Here's a breakdown of the different methods:
1. Resizing Track Height Individually:
- Drag the Track Header Divider: In the Arrangement View or Session View, place your cursor on the horizontal line that separates track headers. The cursor will change to a double arrow. Click and drag up or down to adjust the track's height.
- Using Trackpad Gestures (with Alt/Option): Press and hold the Alt (Windows) or Option (Mac) key while using a pinch gesture on a supported trackpad or touchscreen. This provides a more fluid resizing experience.
2. Resizing All Tracks Simultaneously (Arrangement View Only):
- Hold Alt/Option While Resizing: In the Arrangement View, select any track header. Hold down the Alt (Windows) or Option (Mac) key while dragging the bottom edge of that track's header. This will uniformly resize all tracks in the Arrangement View.
3. Using Keyboard Shortcuts (Height Presets):
Although Ableton doesn't have a keyboard shortcut to resize continuously, it does let you set predefined track heights. You can create custom key mappings using your computer's OS or third-party tools.
In summary, you can resize tracks individually by dragging their headers or using trackpad gestures with Alt/Option. To resize all tracks at once in the Arrangement View, hold Alt/Option while resizing a single track header.
