Yes, MixSurface runs with REAPER on Linux. The extension has a Linux build for x86_64 and ARM64, still marked beta. Unpack it, run the installer, restart REAPER and add MixSurface as a control surface. The app on your phone or tablet is the same as for macOS and Windows.
- On the setup page, choose Download for Linux x86_64 or Download for Linux ARM64, to match your computer.
- Unpack the download and run
./mixsurface-extension/install.sh. It copies reaper_mixsurface.so into~/.config/REAPER/UserPlugins/. - For a portable REAPER, pass its folder:
./mixsurface-extension/install.sh ~/opt/REAPER. - Restart REAPER.
- Open Settings / Preferences → Control / OSC / web, click Add, choose MixSurface and click OK.
- Open MixSurface on your phone or tablet and tap your computer in the list.
Why this happens
- REAPER does not load the extension. The build needs glibc 2.35 or newer: Ubuntu 22.04, Debian 12 and later. Older distributions cannot load it.
- The app does not find REAPER. A firewall is blocking discovery or the connection. Allow UDP 5353, UDP 24780 and TCP 24790, or use Connect by IP on the app’s connection screen.
- Something else looks wrong. The Linux build is tested automatically but has had less real-world use than macOS and Windows. Reports are welcome on the support page.
