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 .

In case you want to make your own Midi controller, you'll need the following:

1. Arduino Due: In our case we used Arduino Due but you can use any Arduino with a native USB port such as Arduino Leonardo.
2. Wires: A lot of them.

3. copper adhesive tape.MDF 5 mm thickness: You can use any materials to build the structure.

4. Acrylic transparent 3 mm Thickness.
5. Conductive paint "Electric paint": We use it to distinguish the black keys on the midi controller layout.

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:

Power 89%

Speed 1.2

Frequency 5000.

• 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.

The base of this project is two libraries:

1. The first one is the " Native Capacitive Sensors without additional Hardware".
2. 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.
