![]() ![]() * Possibility of adding four expansion inputs for external buttons or knobs * 40x2 character LCD, 5x2 characters per encoder/button row * Encoders are pushbutton, and could be ordered in any combination of smooth/detented * 16 RGB Buttons are rubber, from Livid instruments (small) but closer together * USB powered, shows up as a standard MIDI port on Mac/PC * Arduino (Teensy) based, fully programmable and open source.I am finishing the PCB design and before I have it printed I want to gauge the interest of other people to see if I should just make one or two prototypes for myself, or if I should make a run of 50 or so. If you have any questions, leave a comment below.I've been kicking this idea around for a while and am finally settling on a design for a controller that I'm going to build. Hopefully your DIY midi foot controller is functioning perfectly. Arduinos tend to continually search for inputs if they aren’t connected correctly. If you notice your knobs are outputting some random midi signals, it could be because of a loose or faulty connection. If you have successfully made it to this step, congrats! The hardest part is over. It will walk you through everything you need to know about uploading the midi hex file to your Arduino. Give it a shot! If you’re confused at all with it, Hiduino is covered in-depth in my DIY MIDI Controller course.įollow this guide from Arduino. Unfortunately, it seems like the website with those firmware files went down. This project basically takes the code and tweaks it to be more suitable for a DIY midi foot controller. (aka the boot-loader) There’s even some useful sample code provided as well. That is a bit lame and not as fun, so I’d recommend going with the boot-loader option.įirst, download the corresponding USB Midi Firmware file. In order to make the Arduino show up like a proper midi device, you will need a boot-loader.Īn alternative to this would be to use serial-to-midi software. #include LiquidCrystal lcd(7, 6, 5, 4, 3, 2) #define LED 13 // LED pin on Arduino board #define switch1 8 // 1st Switch #define switch2 9 // 2nd Switch #define MIDI_COMMAND_CONTROL_CHANGE 0xB0 //Variables int switch1LastState = 0 int switch1CurrentState = 0 int switch2LastState = 0 int switch2CurrentState = 0 //Potentiometer controlls (Analog) int volumePot = A3 int volumePrev = 0 int volumeCurrent = 0 int levelPot = A4 int levelPrev = 0 int levelCurrent = 0 int wahPot = A2 int wahLevelPrev = 0 int wahLevelCurrent = 0 // the format of the message to send Via serial typedef union Compile the code and you shouldn’t get any errors. (If you don’t have it, you can download it here)Ĭopy & paste the code from down below into your software. Is the image not big enough for you to read? Click here for a larger version.Ĭonnect your Arduino Uno to your computer via usb as normal. Everything is color coded to make your life a bit easier. The first step is to get everything wired-up correctly. <– Let me save you some time! Click the orange shopping cart on the left to add all of the materials to your cart on. LCD to display info information such as volume level, stompbox status, and your current patch name.Also, let me know if building custom enclosures is something you’d be interested in learning more about in the comment section below. I’ll leave that up to your interpretation. The enclosure can be made out of just about anything. It is made using my favorite board of all time, the Arduino Uno.īasically, you’ll be making a very customizable midi foot controller. What we’ll be making is a very functional midi foot controller. ![]() Even if you’re a hobby musician that doesn’t know anything about circuitry or programming, this book breaks it down to an understandable sense. If you want to become a master at making your own custom controller, this is the book for you! Packed with 11 action-packed chapters that include downloadable images, schematics, sample code, and libraries. Recommended course: The DIY MIDI Controller Course. Make sure to share this article on social media if find it helpful, awesome, or both! Let me know what you think of this build in the comment section below! The article there was good, but I wanted to make it even more clear and easy-to-follow. In this article, we’ll be building a DIY midi foot controller that was inspired by an article on the very cool and helpful site, ‘ Randumb Page’. Maybe you haven’t found a foot controller that does everything you desire. Maybe you don’t want to spend $150+ on a foot controller. Midi foot controllers are a game-changing piece of equipment for guitarists and musicians alike. ![]()
