Guitar Hero MIDI Controller

Slapyak has an interesting tutorial on creating a Guitar Hero MIDI controller.

With the current version you can:

  • play 2 octaves of an 8 note scale at a time
  • change the starting note anywhere in the range of a regular keyboard
  • change octaves
  • change keys
  • change tonal modes (Ionian, Mixolydian, Lydian, Dorian, Aeolian, Phrygian, Locrian)
  • change the timbre of a sound
  • change the resonance of a sound
  • use the whammy bar to pitchbend
  • play chords in the mode you have the guitar set to (major/minor/etc.)
  • rock out with a video game toy

Here’s a high-level flow for the MIDI controller:

Guitar –> Arduino –> LEDs & MIDI –> external MIDI device.

Details are available at the Slapyak site.
