Open your project in REAPER and press Cmd+Ctrl+M on a Mac or Ctrl+Shift+R on Windows. The Mixroadie panel opens inside REAPER. Updated 28 October 2026 Mixroadie is a panel inside REAPER, not an app you open on its own and not a plugin on a track. 1. Open REAPER with the song you want to work on. 2. **Save the project.** Mixroadie reads the saved project file. 3. Press **Cmd+Ctrl+M** on a Mac, or **Ctrl+Shift+R** on Windows. The panel opens. Dock it wherever you like, and REAPER remembers where. ## Open it from the Action List instead 1. In REAPER, choose **Actions ▸ Show action list**. 2. Type **mixroadie** in the filter box. 3. Select the Mixroadie panel and press **Run**. To open it with one click, drag that action onto a REAPER toolbar. To give it a different key, select it and press **Add…**. ## Closing and reopening it Closing the panel doesn’t stop Mixroadie: pressing the shortcut again brings the same panel back. If an older REAPER asks what to do about the Mixroadie script that is already running, choose **New instance** and tick “Remember my answer”. Never choose “Terminate instances” while Mixroadie is applying changes. Nothing happens when you press the shortcut? See [The shortcut doesn’t open the panel](https://mixroadie.com/help/shortcut-does-not-work/). Still stuck? Write to us with your computer (Mac or Windows and its version), your REAPER version and what you see. A screenshot helps.
