Install & Setup

Get A1R running inside Ableton Live in about 5 minutes.

A1R needs Ableton Live 11 or newer on Windows or macOS. It installs as a Control Surface (a small remote script inside Ableton) plus a lightweight standalone server you control from any browser.

Download & run the installer. Your download link is in your license email, or on your account page.
Open Ableton Live → Preferences (Ctrl/Cmd + ,) → Link/Tempo/MIDI.
Under Control Surface, select A1R_MAX (or your tier's control surface). Leave Input and Output = None.
Launch A1R from the Start menu / Desktop shortcut. It lives in the tray and doesn't have to wait for Ableton.
A1R opens your browser automatically on launch. The port depends on your tier — CORE 4444, LITE 55555, PRO 4321, MAX 1234, ULTRA (no port needed, just localhost). On a phone/tablet on the same Wi-Fi, open the address A1R shows on screen.
Activate your license. Done — build your setlist in Ableton and it appears instantly.

Ableton Preferences Control Surface = A1R MAX

In Ableton: Preferences → Link/Tempo/MIDI → set Control Surface to A1R MAX, Input & Output = None.

If another control-surface script also grabs transport, it can conflict. A1R only needs the Control Surface slot — keep Input/Output on None.
