Mair Remote

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 3.9+

Installation

git clone https://github.com/onyx-and-iris/xair-api-python
cd xair-api-python

Just the interface:

pip install .

With development dependencies:

pip install -e .['development']

Usage

Connection

An ini file named config.ini, placed into the current working directory of your code may be used to configure the mixers ip. It's contents should resemble:

[connection]
ip=<ip address>

Alternatively you may state it explicitly as an argument to mair.connect()

Example 1

import mair

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

if __name__ == '__main__':
    kind_id = 'MR18'
    ip = '<ip address>'

    main()

API

• XR18

Tests

People plug expensive equipment into these mixers, the unit tests adjust parameter values such as gain sliders etc. My advice is to unplug all equipment from the mixer before running these tests. No tests alter phantom power state. Save your current settings to a snapshot first.

First make sure you installed the development dependencies

To run the tests from tests directory:

pytest -v.
