This plugin provides audio source(s) from REAC, which is an audio-over-ethernet protocol developed by Roland.

Hardware connection

This plugin was developed and tested with Roland M-200i as the connection drawn in a figure below.

In the computer running OBS Studio, it is recommended to have a dedicated ethernet device to connect to REAC network.



This plugin is provided "as is" without warranty of any kind, either expressed or implied, and the plugin is to be used at your own risk. The author of this plugin has no relationship with Roland. Do not ask Roland for support of this plugin.


Ethernet device

Specifies which ethernet device to be monitored.

Channel L / R
Specify left and right channel to be captured.

  • Not all binaries are tested.
    • MacOS: A package is provided but never tested.
    • Ubuntu: A deb package is provided but never tested. The source code is tested on CentOS 8.
  • Currently this plugin is not provided for Windows.
  • Only 48 kHz sampling frequency is supported since the sampling frequency is hard-coded to 48 kHz in the plugin. To use this plugin, you have to set the sampling frequency of the REAC device to 48 kHz. (Still you can set any sampling frequency on OBS Studio and libobs will automatically convert it.)
