MIDI (Musical Instrument Digital Interface) is a standard for electronic musical devices to communicate. This page is a brief introduction to MIDI that should explain what you need to know to map MIDI controllers to Mixxx.
MIDI is a widely used standard that a lot of hardware and software support. It dates back to the 1980s when it was used to make synthesizers, samplers, and sequencers communicate. These older devices used cables with 5-pin DIN connectors to carry MIDI signals. Most MIDI devices today send the MIDI signals over a USB cable. Some modern devices can also can use cables with the 5-pin DIN connectors. DJ controllers with these 5-pin DIN connectors do not ordinarily use them to send signals to the computer; they are used to communicate via MIDI with other gear and the ability to use MIDI without being plugged into a computer (although they need to be plugged into another power source without a USB cable supplying power).
Mixxx is a complete free alternative to paid DJ software that works even better than some of the commercial programs. It's strongest competitor is the Virtual DJ Free Home Edition but Mixxx has all the features enabled and Virtual DJ doesn't (such as looping and fully editable effects not to mention MIDI and transport control). Mixxx crashing is beside the point to someone who has spent $600+ on a controller if Mixxx doesn't even support the controller. Reviewers have been saying for years that the haphazard controller support is one of Mixxx's biggest weak points and not much has been done about it till now.

Controllers that comply with the USB MIDI class standard (also called “class compliant” devices) do not require any special drivers. Most controllers are USB MIDI class compliant, but not all. See the Mixxx DJ Hardware Guide for information about particular controllers.
The Kontrol S4 MK2 is a USB class compliant audio, HID, and MIDI device, so it is compatible with Mixxx without any proprietary drivers on GNU/Linux and Mac OS X. On Windows, it is recommended to install the driver from Native Instruments and select the ASIO sound API in the Sound Hardware section of Mixxx's Preferences. May 17, 2017 Run Mixxx in developer mode with the command 'mixxx -developer'. This is necessary because Mixxx hides the 'Midi Through' interface but we need it. Start Mixxx, go to 'Options - Preferences - Controllers', select 'Midi Through', enable it and load the Preset 'MIDI for light' from the list. This will enable the sending of Midi events.

Mixxx displays the numbers in MIDI signals in hexadecimal. If you are unfamiliar with hexadecimal numbers, read this tutorial.

An explanation of the MIDI signals that your controller sends to computers and how it reacts to MIDI signals that computers send to it should be available from the controller manufacturer. This is likely in a document on the product page for your controller on the manufacturer's website or in the support section of the website. If it is not in a separate document, it is likely at the end of the manual. Unfortunately, not every manufacturer provides this information.
