However, this project is not comparable with high-end professional level DJ Controllers which are a lot more complex and perform other functions (pre-cueing, integrated sound cards, etc). A popular format for these messages is MIDI, which is pretty much what we will use here. They read input from a bunch of sensors (buttons, sliders, knobs, etc) and convert the input into control messages for the DJ software. Using a mouse and keyboard to DJ quickly becomes limiting after some time, if you have used a software-based DJ Controller for some time, you know what I mean.Īt the hardware level, entry-level DJ Controllers are very simple devices. She is using multiple DJ Controllers in this video to mix four tracks at once), sometimes akin to playing an instrument! The DJ Controller gives the DJ a physical interface to quickly perform all these actions. This all happens live and is pretty impressive if the DJ is good ( See this video, WARNING: Contains explicit language. A music-mixing program allows a DJ to play songs and add effects, “scratch” the track, control audio equalizers, volume, play loops and samples, and most importantly, mix multiple songs together to seamlessly switch from one song to another. A DJ Controller is a physical device that you can connect to a computer that is equipped with a software based music-mixing program. I will include a more extensive list of required materials, skills, and software later on in the Instructable.įunny you should ask. A better microcontroller with more pins would be able to support more inputs, something to keep in mind if you are going to build this project differently. The microcontroller code I provide is written using Energia and may transfer to Arduino with little effort, other microcontrollers may need to have the code ported to them specifically, which wouldn’t be too hard. My specific DJ Controller uses an early revision of the TI MSP430 Launchpad, a microcontroller development platform known for its low price ($10) and hobbyist following. I modeled my controller after the Numark Mixtrack II. See the section on what I like to call “quasi-MIDI” later in this introduction. The final product is simply something that takes analog and digital inputs and provides a unique and easy method to turn them into MIDI outputs. My favorite aspect of this project is how open it is to modification. If you were to take this idea and expand it and polish it, you could end up with a really nice and/or totally different MIDI device. The DJ Controller I will construct in this Instructable will provide you with just one example of what you could build using the code, structure, and process that I show here. They are out there for around $100 USD, but I am also into DIY! I have a passion for both music and electronics and wanted a way to combine the two, so I decided to build a custom DJ controller with low-cost and rapid construction in mind. I’m only a hobbyist DJ and didn’t really want to spend a lot of money on my first DJ Controller.

And they are also traditionally expensive. Hardware DJ Controllers are traditionally the next step after getting one’s feet wet using a software-based DJ Controller. I enjoy DJing because it provides a more interesting, involved, and interactive music-listening experience, whether in company of friends or while in private. Many people are getting into DJing these days, whether as a means of self-expression or a way to make extra money.
