Xair API

This package offers a python interface for the Behringer XAir, Midas MR series of digital rack mixers. I only have access to an MR18 for testing so if there is an error in the kind maps feel free to raise an issue or PR.

For an outline of past/future changes refer to: CHANGELOG

Prerequisites

• Python 3.10 or greater

Installation

pip install xair-api

Usage

Connection

A toml file named config.toml, placed into the current working directory of your code may be used to configure the mixers ip. A valid config.toml may resemble:

[connection]
ip = "<ip address>"

Alternatively you may pass it as a keyword argument.

Example

import xair_api


def main():
    kind_id = "XR18"
    ip = "<ip address>"

    with xair_api.connect(kind_id, ip=ip) as mixer:
        mixer.strip[8].config.name = "sm7b"
        mixer.strip[8].mix.on = True
        print(
            f"strip 09 ({mixer.strip[8].config.name}) on has been set to {mixer.strip[8].mix.on}"
        )


if __name__ == "__main__":
    main()

xair_api.connect(kind_id, ip=ip, delay=0.02, connect_timeout=2)

Currently the following devices are supported:

• MR18
• XR18
• XR16
• XR12

The X32 is partially supported. However, this document covers specifically the XAir series.

The following keyword arguments may be passed:

• ip: ip address of the mixer
• port: mixer port, defaults to 10023 for x32 and 10024 for xair
• delay: a delay between each command (applies to the getters). Defaults to 20ms.
  • a note about delay, stability may rely on network connection. For wired connections the delay can be safely reduced.
• connect_timeout: amount of time to wait for a validated connection. Defaults to 2s.

Tests

Unplug any expensive equipment before running tests. Save your current settings to a snapshot first.

First make sure you installed the development dependencies

To run all tests:

pytest -v.
