Kord Kontroller – emphasizing common tonal relationships in Western music theory
OnHackaday.io, via Hackaday, the Kord Kontroller is a musical interface that maps common chordal relationships in Western music theory. The controller is laid out into two sections: the key selector area and tonal selector area.
The layout of the Kord Kontroller puts all the scale degrees arranged in the circle of fifths in the top of the keyboard. To play 90% of western music, you’ll hit one button for a I chord, move one button to the left for a IV chord, and two buttons to the right for a V chord. Chord quality is determined by the bottom of the keyboard, with buttons for flat thirds, fourths, ninths, elevenths and fourteenths replacing or augmenting notes in the chords you want to play. Since this is effectively a MIDI controller, there are buttons to change octaves and modes.
The controller uses the Adafruit UNTZtrument! Open-Source 8×8 Grid Controller Kit with 8×8 White LEDs. Maybe they might look to port it to the new NeoTrellis?
