Introduction: Touch Midi Controller (DIY)
The idea behind this project is to make a functional Midi controller, easy to build with low cost, so anyone can build it.
We designed a full size keyboard shape midi controller not just a few buttons and knobs.
This project is done by fablab Irbid`s coordinator, Yazan ABU Dabaseh .
Step 1: Materials and Tools.
In case you want to make your own Midi controller, you'll need the following:
- Arduino Due: In our case we used Arduino Due but you can use any Arduino with a native USB port such as Arduino Leonardo.
- Wires: A lot of them.
copper adhesive tape.MDF 5 mm thickness: You can use any materials to build the structure.
- Acrylic transparent 3 mm Thickness.
- Conductive paint "Electric paint": We use it to distinguish the black keys on the midi controller layout.
Step 2: Design and Manufacturing
We used AutoCAD software to do the design. We wanted to design something that would look close to a midi controller.
To cut the design we used Trotec speedy 400 machine.
We used Mdf 5 mm,the settings for cutting is:
Step 3: Putting It All Together
- Cut the adhesive copper tape manually to fit the size of each key.
- Carefully we tapped each copper key to its location.
- Connect each copper key to a single Arduino pin using wires.
Step 4: Programming
The base of this project is two libraries:
- The first one is the " Native Capacitive Sensors without additional Hardware".
- The second one is " MIDIUSB library "
So, basically we defined each key on a single pin on the Arduino, then we linked them with the midi USB library, to send a midi signal through the native USB to a computer.
