A couple years ago, bay area start-up Irijule hit the ground running with its first endeavour, the TheoryBoard, a MIDI controller which aimed to put the power of music theory right at your fingertips. Well, after huge success with garnering the much needed support and financial backing, Irijule now returns this summer with an updated version of the TheoryBoard, packing up to 1.9 billion chord variations and much, more more!


Dubbing this new model the "Thy333", it has already way oversurpassed the mark needed to implement full production and marketing, and so we can expect that this will indeed be hitting the stores soon enough!


Features and specs for the TheoryBoard Thy333 are as follows:


  • 840 Chromatic and Diatonic Scales, Chords + Melody

  • 1,981,808,640 Possible Chord Combinations via the Theory Engine (Patent)

  • 96 Velocity Sensitive Keys with Polyphonic Aftertouch

  • 24 Hot Swap Keys for on-the-fly Direct Modulation & Modal Interchange scale switching

  • 96 RGB LEDs provide visual link between chord side and melody side

  • Touch Screen Display with OLED Screen

  • On-the-fly Chord Augmentation (Spread, Voicing, Octave)

  • Octave Stacking Technology

  • Pentatonic Scale Systems

  • Guitar Voicing Feature

  • Live Note Update Function

  • Ports: USB MIDI, TRS-A MIDI Out, TRS Sustain In, 5V Power In

  • Compatible with computers, synthesizers, and mobile devices

  • Dimensions: 27.25” x 5.5” x 0.9"


The project still has 56 more days to go on Kickstarter, where you can pre-order the TheoryBoard for $499 (58% discount), or even the limited edition red color TheoryBoard for a backing of $599 (41% discount). Expected MSRP will be $1199.
