Soundcraft UI Midi Control is a free Chrome add-on that allows users to configure a midi controller to work with the web interface elements of Soundcraft UI digital mixers. With this add-on, users can adjust the volume, mute, and solo of selected channels on the main web interface screen, as well as assign functions such as Mute All, Mute FX, and Tap Tempo. The controller settings can be saved and reset either partially or completely.

In addition to midi control, the add-on also provides enhanced keyboard control. Users can change the volume of selected channels using the 'PageUp' and 'PageDown' keys or the '>' and '<' keys. They can also set the bpm Tap Tempo using the 'T' key. The add-on also allows keyboard control of volume, mute, and solo functions in the player widget.

Please note that starting from version 76 of the Chrome browser, the functionality of the add-on is limited due to the blocking of the Web-Midi-API on resources without HTTPS. However, there are two possible solutions to overcome this limitation. The first solution involves enabling the flag #unsafely-treat-insecure-origin-as-secure in the browser's flags section and adding the URLs of the web interface. The second solution is to use supported versions of Chromium (v.45 - v.76), which can be downloaded from the official repository.

It is important to have the necessary drivers for the midi controller installed on the operating system and to connect the controller before launching Google Chrome. Clearing the cache and cookies for the web interface site is also recommended for optimal performance. If users encounter any issues with the add-on, they can contact the developer at

Overall, Soundcraft UI Midi Control is a valuable tool for musicians, vocalists, and programmers who want to enhance their control over Soundcraft UI digital mixers through midi and keyboard inputs.
