| description | AX-first automation for Logic Pro — transport, tracks, tempo, mixer, and view controls |
Logic Pro Automation
Connect
connect_app({ name: "Logic Pro" })
Backends
- Primary: Accessibility automation (menu bar, transport, tracks, mixer, view toggles)
- Prefer menu bar actions over keyboard shortcuts — shortcuts steal focus and can misfire
Layout
Logic Pro's main window has these regions (top to bottom, left to right):
- Control Bar (top) — transport buttons, LCD display (tempo/time sig/key), view toggles
- Inspector (left panel) — Region and Track properties, channel strip
- Tracks Area (center) — timeline with track headers and regions
- Editors/Mixer (bottom, toggled) — Piano Roll, Audio Editor, Mixer, etc.
Key Elements
Menu Bar (preferred for actions)
Use select_menu_item instead of keyboard shortcuts — it's a single atomic call via System Events, no focus stealing.

Gotchas
- Transport buttons (Play, Record, Cycle, etc.) are checkboxes, not buttons — they toggle on/off. Stop is the only button.
- The tempo is a slider (label: "Tempo", min: 5, max: 990). Use
fill to set it — under the hood this uses AXIncrement/AXDecrement in steps of ~10, so the final value may overshoot slightly.
- AXSetValue on Logic Pro sliders does NOT set the absolute value — it just increments by 1. Always use
fill which handles this correctly via AXIncrement/AXDecrement.
- Many channel strip controls in the Inspector are disabled by default — they become enabled when the track is selected and the inspector section is expanded.
- "New Track" menu items open a dialog — after clicking the menu item, you may need to interact with the dialog to finalize track creation.
- The Screensets menu uses numbers (1-9) as menu bar items — don't confuse with regular menus.
