Connect each phone or tablet to the same REAPER, the same way as the first one. There is no main device: each one connects on its own, and what you change in REAPER from one shows up on the others. Connecting several devices is free.
- Install the app on each device and open it on the same network as the computer (or on a USB cable).
- On each device, tap your REAPER in the list on the connection screen.
- Give each device its own job: the mixer on one, a Control View page on another, a monitor mix in Sends on Fader on a third.
- Move a fader, mute a track or change a plugin on one device. The others follow.
What is shared and what is not
- Shared through REAPER: everything REAPER holds (levels, mutes, plugins, automation), plus what you build in MixSurface: layers and pinned tracks (saved with the project), plugin templates and Control View pages.
- Per device: settings such as Follow, Visible, the ruler and Fine mode, the toolbar layout each device picked, and which layer, bank or page each device is looking at.
With Follow on in the top bar (Follow REAPER selection in ⋮ More), Channel Detail on that device jumps to whichever track REAPER selects. It is set per device, so a tablet parked on an EQ is not dragged around by someone else’s selection.
If it doesn’t work
- Two devices fight over REAPER’s mixer view. Only one device should use Drive REAPER’s mixer under Visible; the last tap wins.
- Two people ride the same fader. Both moves reach REAPER and the last one wins. Split the work by layer or by bus.
- A second device does not find REAPER. Use Connect by IP on the connection screen.
