Mair Remote

This package offers a python interface to the Midas MR18 digital rack mixer. All testing was done using a Midas MR18 but I've been informed that the software for XR18 is identical. Midas are not affiliated with/nor do they support this package in any way.

Prerequisites

• Python 3.9+

Installation

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

Currently the following devices are support:

• XR18
• MR18

However, this interface can be expanded upon to support other devices.
