MOTU Control

A JavaScript controller for MOTU devices using the HTTP/JSON API. Works in both browsers and NodeJS

Usage

Install using your package manager of choice:

yarn add motu-control

Then import and initialize it with the HTTP address of the MOTU device:

import MOTU from "motu-control";

const motu = new MOTU("http://10.1.53.19");

Once initialized, the MOTU instance will automatically long-poll the MOTU device to get updates on the mixers and channels. It currently filters out all but analog inputs and outputs, aux mixers, and mixer groups. All of this information can be accessed from two dynamic (getter) properties on the class:

console.log(motu.mixerInputChannels);

// [
//   {
//     defaultName: 'In 1',
//     name: 'Bridge Mic (Front)',
//     src: '0:0',
//     chan: 0,
//     input: {
//       defaultName: 'Analog 1',
//       trimRange: '-96:22',
//       name: 'Bridge Mic 1',
//       trim: 22
//     },
//     type: 'chan',
//     mix: {
//       config: [Object],
//       hpf: [Object],
//       eq: [Object],
//       gate: [Object],
//       comp: [Object],
//       matrix: [Object]
//     }
//   },
//   ...
// ]

console.log(motu.mixerOutputChannels);

// [
//     {
//     defaultName: 'Aux 1',
//     name: 'Bridge L',
//     chan: 0,
//     type: 'aux',
//     mix: { config: [Object], eq: [Object], matrix: [Object], tb: [Object] }
//   },
//   ...
// ]

Updating the MOTU is as easy as modifying the values in the mix object. This will automatically send the update to the MOTU. Multiple value modifications applied at the same time will be batched into a single request to limit the number of network messages sent.

When setting any of these values, you must only use numerical input; any other type of value will not perform any operation.

motu.mixerInputChannels[0].mix.matrix.fader = 0.5;

// A PATCH request is sent to the MOTU, triggering the update.
