DIY MIDI Keyboard Controller (PCB Kit)

Fun little project kit to build your own little MIDI Keyboard. Basic PCB soldering skills required.

Specifications:

• MIDI Out - Connect to your MIDI synth, keyboard or computer
• MIDI In - Play music notes through the in-built piezo buzzer
• Monochromatic (will only play one note at a time)
• Pitch Control
• Powered by 5v USB

Pressing two buttons at one (i.e C & D keys) will play the sharp notes (i.e C#).
