Set up your DAW

Reaper

Jude connects to Reaper over OSC, Reaper's built-in remote-control protocol. It gives the engineer rich readback — real dB values and every track in the project live at once — and it's one entry in Reaper's preferences.

Setup

  1. In Jude, open Settings → DAW and choose Reaper (OSC).
  2. In Reaper, open Preferences → Control/OSC/web, click Add, and choose OSC (Open Sound Control).
  3. Set the mode to Configure device IP+port and enter:
    • Device IP: 127.0.0.1 (Jude and Reaper are on the same Mac)
    • Receive on port: 8000
    • Send to port: 9000
  4. Click OK. The DAW light in Jude's header turns green when Reaper starts talking.

Launch order doesn't matter with OSC — start Jude and Reaper in whichever order you like, and Jude finds Reaper either way.

These port numbers match Jude's defaults, shown in Settings → DAW → OSC connection. If you ever change them, change them in both places: Reaper's "Receive on port" is Jude's DAW port, and "Send to port" is Jude's port.

Jude's Reaper script

Adding, naming, moving and removing tracks, inputs, instruments, positions, tempo, and markers and regions go through a small ReaScript that Jude puts in Reaper's own Scripts folder. It installs itself the first time it's needed while Reaper is running — there's nothing to set up. Settings → DAW → Track management scripting shows whether it's installed and answering, and can install it ahead of time.

Good to know in Reaper

  • Dialogs pause the link. When Reaper has a dialog open, it stops talking to control surfaces until you dismiss it. Jude may briefly show the DAW as not responding; it recovers by itself the moment the dialog closes.
