The aim of this post is as a starting point for making your own DIY MIDI controller. Although many MIDI controllers can be purchased off the shelf, there may be times when a DIY approach is more economical or more appropriate in terms of specific design and mapping.
This is one of the simplest MIDI controllers that I can think of – it is just a pot (i.e. “knob”) that sends USB MIDI continuous controller data on CC#1, channel 1.
• 1 x Teensy board with pins
• 1 x USB A to B mini cable
• 1 x 100kΩ B-type potentiometer
• 1 x mini breadboard
• 3 x breadboard jumpers (can use a jumper kit for instance)
• Arduino IDE
• A digital audio workstation (DAW) such as Ableton Live
The Teensy is a complete USB-based microcontoller development system, in a very small footprint! All programming is done via the USB port. No special programmer is needed, only a standard “Mini-B” USB cable and a PC or Macintosh with a USB port. This is the latest version, 2.0.
- USB can be any type of device
- AVR processor, 16 MHz
- Single pushbutton programming
- Easy to use Teensy Loader application
- Free software development tools
- Works with Mac OS X, Linux & Windows
- Tiny size, perfect for many projects
- Available with pins for solderless breadboard
Comes with assembled Teensy board (ATmega32u4 with bootloader preinstalled) and header to allow easy breadboarding. We suggest using AVR-gcc (like WinAVR) with the LUFA library or ‘Teensyduino’ Be sure to check out the multiple resources available at PJRC!
