The Dualo Du-touch, a unique keyboard instrument with 2 physical keyboards, and a unique note array, is in production and the first run has shipped, with more available for purchase with a November ship date. It's quite a wild, grass-roots project, done by a bunch of keen amateurs, yet the product just might shake up the musical world. 

In one light, compact and very portable device, you have a complete keyboard (albeit split over two physical sub-keyboards). What is impressive is what they have packed into it; it's "basic" features are, well basically everything: 

5-octave controller

  • 166 “Pressure sensors” – not just keys – with velocity sensitivity
  • Dynamically lit keys, both for performance and training
  • 3 dimension inertial sensor unit – pitch, yaw and roll - this is a real crowd-pleaser
  • Slide controls near the keys – so that they can be accessed instantly during play


  • 112 instruments, 4 percussion kits
  • 8 effects: distortion, delay, chorus, compression, reverb, pitch modulation, expression, wah-wah


  • dynamically create, loop and overlay musical patterns
  • Looping can be triggered while playing
  • Can record and save your performances as files

A truly unusual note lay-out

Now, it has a rather novel note layout. Within an octave, two hands play alternate notes!  Here's why: in this instrument notes go up only a semi-tone side-ways, but go up a third in the "outwards from the body" direction. On one hand the notes go up on the odd notes:  root => thirds => fifths => sevenths => ninths etc. So on the other hand you must play the "even" notes, the Seconds => Forths => Sixths => octaves, etc. This may take a bit of time to understand but is worth the effort:

It makes an interesting musical sense: in lots of common music chords and notes are played in a odd-even, odd-even pattern. With this instrument, such common patterns will be about twice as easy / fast to play.  

Which finger plays what ...

Although the keyboard is physically symmetric, the instrument is not played symmetrically.This anti-symmetric system is interesting in light of recent discoveries concerning symmetry and keyboard learning.

The inventors are French, so the explanation of how it works is in French:

Things are definitely heating up in the alternate keyboard realm.
